80 series coil & shock specs

A few years back 80 series suspension was fairly easy to figure out & purchase since there was only a few of options to chose from. Recently there has been a few suppliers stepping up to play in the USA 80 series market offering more options. Now with a plethora of options, it has become confusing to figure out.

I compiled a bunch of specs on suspension components that I have researched & I wanted to get it all in one place for reference. Enjoy.

(If you see any info wrong then please PM me to get corrected.)

Links that I have resourced specs & info from.

If you like you ride & handling of the stock coils but want to use a longer shock like the L shock then one can just add a 30mm coil spacer on top of the stock coil to get enough free height to prevent the coils dropping out at full extension of the longer L shock of 26.5"

AS basic as I can tell you is the L shock was made for an 850J coil which the free height = 20.27"/20.67" The shortest OEM coil stands at 18.5" then add the spacer 30mm/ 1.18=19.68". I ran a 850 equivalent free height coils of 19.48" with the L sock without any issues of coils falling out, so it is safe to say as long as your free height is at least 19.5" you can run a shock the extends to 26.5" like the OME L shock without coil falling out. Does this make since?
GW Nugget's Family Haulin Lx450 build page #12 post #224
If you add a 30mm coil spacer to stock coils one can run the longer OME L shocks.
The OME L shock suits the 850J coil which is 20.27"/20.67" in free height.
If any other coil with same free height or taller can run a OME L shock which extends out to 26.5" measured at the collars.
So, if you add a 30mm to a stock coil of 19" then it comes out to 20.18"
Even the shortest replacement coil (48131-6A570) at 18.5" will work.
I have ran 850 coils with L shocks no problems... they are 19.49"/19.88"
See picture below.
OME shock length just doesn't make sense!

What is my lift height?
I found this.

Another I found... its very close to the above, but shows where to measure the rear.


Also the general consensuses is 20" from center of hub to bottom of flare (COHTBOF) is were 20 year old spring generally net. So, if you have a 23" COHTBOF it is a good indication it is approx. 3" of lift front & rear.

@TRAIL TAILOR posted in one of his threads this:
A few years back we put new Toyota springs on Andrea's 97 from the dealer. After the new springs, the front was at 20.375" and the rear at 21.125" I just measured it and my 92.

97- 3 year springs and 24,680 miles on them-- Front 20.00 Rear 20.625"
92- guaranteed these are original with 206K on them-- From 20.00 Rear 20.50"

King and TD say their coils are based on lift over factory "showroom" heights.

My actual measurements.
My measurement of the 60070L is .25" longer than spec. 15.25"/26.5"

Pics below is of front 6007L shock

The hybrid or level combinations are as follows for lightly loaded rigs.

One can use the longer L shocks (60070L/60071L) to keep coils captive.

(Rec BS 1.5")
GS59-685 rear - 17.00" - 28.74" (Rec BS 3")

Yellow shock Bump Stop Recommendation
(As per David Otero @ Dobinson)
4" lift shocks:
GS45-912 needs about .5" of bump stop extension with a minimum of 525mm/20.67" coil length
GS59-687 needs 2” of bump ext. with a 505mm/19.88" minimum coil free height to stay trapped
6" lift shocks:
GS59-684 needs about 1.5” bump stop spacing with a minimum coil length of 570mm/22.44"
GS59-685 needs a 3” extension and minimum of approx 555mm/21.85" coil length to stay trapped

The 4" lift Dobinson yellows are a bit longer than a OME real L shock.
(Hmm... Also notice there is a little play room to stack additional washers to change shock length)

I have been told the Dobinson yellow shocks are softer on compression & slower on rebound compared to the OME L shocks.

Dobinson 4" Flexi Coils

@Nay added these comments in post #92:
Hopefully adding something useful this time. First @GW Nugget is right - the color scheme is meant to be:


It’s like adding teenage girl nail polish to toxic sea foam.

Second, the free height of the 4” Flexi rear coils is almost 23” - that spec was missing in the original post. Having seen the rears in person now I have also ordered the fronts.



@Nay added these comments in post #139
Dobinson’s front 4” Flexi installed. This coil is shorter than the rear, about 22.5” free height. Way more coil than the front can use in any case - I dropped the whole front end on both sides to the stretch point of the brake line, leveraged out the old coil with a 4’ bar and kick method, and then used compressors again for the Flexi.


As compared to the FOR Gen II it replaces.


I’ve picked up about an inch of lift at all four corners. I’m right about 25.5 hub to fender (no flares), wrapped around the tire. I’ll measure more carefully tomorrow in the daylight.

Ride quality for my relatively light rig with the Fox 2.0 remote reservoir shocks is outstanding. The front feels pretty much the same outside of what I think was some coil damage from my accident - the front driver’s got torqued pretty good with frame bend and a bent radius arm and it had lost about a half inch of height.

It’s the rear that feels like it has more control - there is a lot of extra coil and it feels extremely well dialed. This seems a shift in rear coil design philosophy, more than just “longer shock”.

Definitely a clean 4-4.5” lift and seems very well thought out and executed. My 37’s are going to look a little bit small now. The coil color, OTOH, is perfect.

  2. OME L shock compared to 41mm Tough Dog...


    Obligatory coil comparison. OME 863J and Tourflex 3".


    41mm foam cell shocks are made by either Gabriel or Tenneco (Monroe) in the US or Mexico. Then sent to AUS for QA/QC, batch testing and final assembly/packaging.

    Mine have Gabriel on the bushing.

  3. And, done with the front...


    OME L front shocks are a bit longer than the 41mm Tough Dog.


    And, the springs side by side. Tourflex 3" vs. OME 850J.


    Very pleased with @reevesci 's excellent service, great communication, and quality product. Look forward to my next purchase from him, the redneck skid plate.

With such a low COG and tall free height that allows the longer 28" shock, I believe this to be a true little hidden jem.

Slinky vs OME 850J

Slinky rear bump stop is 30mm taller than stock. (this would equal a 30mm bump stop extension).

Resourced from:
80 shock thread - familiar territory could use update

Our slinky coils front AC7498 are 260 lb [SNOWY has these]
rim to fender is 800-825mm, and because the last 2 5/8" thick coils are completely dead, it allows us to trim heights to suit by removing a coil if we need to.

We also have a 290 lb front for fully loaded diesels. This is a linear coil for the 670mm shock length, but not Slinkies. Its an 810 - 820mm rim to fender height.

Our AC7501 rears are 270lb intermediate, 810-830mm rim to fender and AC7511 320 lb HD 810-830mm rim to fender.

330 lb longer lineear coil 30mm higher AC7511E extra HD 830-850mm rim to fender.

We also have a 495 lb rear coil for big heavy extended chassis tourers 830-860mm rim to fender.

All our slinky coils are 160 lb on the tapered wire section.

We normally try and work to a 30mm [1 1/4"] rake when vehicle accessory fitted but unloaded as we see it to install.

Our intermediate coils drop approx 12mm [1/2"] per 100kg [220lbs] of load.

Our HD drop approx 8mm [.315"] per 100 kg [220lbs] of load.

How we measure those, rim to fender, for 80 we talk 16" rim, and add 12mm for 17s, 24mm for 18s, etc.

This makes it easier with deep dish wheels, than centre of hub, and removes tyre pressure variants.

TJM 2" Progressive
80 Series Coils | TJM USA
Shock Absorbers | TJM USA

(Contribution of specs by @Shoredreamer from the thread Where to buy TJM progressive springs?)

TJM Front 50mm- 770FR80C: 21.2”/20.8” free ht. 16.5mm coil, 10.2 winds
TJM Rear 50mm - 770RR80C: 20.27”/19.8” free ht. 17mm coil, 8.8 winds (145/250lbs)
They are a taller coil with more winds vs. OME medium/heavy which likely means a more supple ride and lower spring rate. Very good on an unladen 80.

TJM Tiger 9 way adj shocks-
Front 14.6”/24” 9.4” stroke
Rear 15.15”/24.25” 9.1” stroke





After a lot of reading I have found that most people who have stock to light rigs really love the suspension it's really great but once you start putting heavy thing's in your rig like armor and bumpers and drawers and stuff these rear coils just can't handle the weight. @Shoredreamer had this set up till his 80 got fat.
@Heckraiser posted this about his 2" TJM 50mm lift.

For reference, this is TJM 50mm progressive with 315's no extra weight in rig. No 3rd row = pretty level, very minor stinkbug. 2nd and 3rd row out = slight stinkbug. Squats just a little bit with my trailer hooked up (about 120# tongue weight?) No bump stop spacers and no issues with 315's *as long as you keep the weight down*

SOF4FM 4" Medium front is for plus 150 lbs
Driver Side 505mm/Passenger Side 515mm ~ wire size approx. 19mm ~ 12.5 turns

SOF4RHP 4" Heavy is for plus 300 lbs
Driver Side – 510mm/20.08"/Passenger Side – 520mm/20.47" ~ wire size 21.5mm ~ 10.25 turns

As per @baldilocks post:
The heavies are a 4” lift spring if your rig weighs something like 7k pounds. Mine lifted my rig almost 6” empty and what I call a full load only mashed them maybe an inch to 1.5” inches so I still had at least a full 4” of lift with my version of a heavy load. And they don’t ride harshly unloaded. A high quality product.

Slee 4" or 6" Suspension Upgrades

Photo Gallery

The Slee lift kits were designed to give you the ultimate in off-road ability yet retain great street manners. Offered as a direct bolt on or DIY kit.

These kits consist of all the parts necessary and recommended to lift the 80 Series correctly while addresses all of the drive line and steering geometry changes when going to a 4" or 6" lift. Using proper spring rates and adjustable rods and arms, together with caster correction methods that does not require drop brackets, you achieve the maximum under carriage clearance without sacrificing driveability.

Slee 6" Lift Kit

* Subject to change

The 6" lift kit was develop as the ultimate off-road kit available for the 80 Series Land Cruiser. This kit approaches the maximum possible lift for a 80 Series Land Cruiser before one enters the world of custom fabrication and redoing the link system due to excessive angles and possible damage/binding when articulating. Although the truck is still 100% drivable and has handling, this is the kit that we recommend for the people that want to run 35" or larger tires and want to play hard.

The Slee 6" coil springs are a heavy spring rate to accommodate most accessories commonly fitted to off-road trucks. The SOF5FM and SOF5RM Medium Load springs are set up to handle 250 lbs in the front and 400 lbs in the rear and still yield a 6" lift. For extra heavy applications the SOF5RH Rear springs can be installed.

The stiffer spring rate were chosen for minimal body roll on-road, yet still retain good articulation off-road. This offers a much improved ride over using a softer spring with spacers to achieve the same lift height.

Caster is addressed by custom Slee front control arms that machined as a single piece from 1.75" plate. The arms are ready for installation with Toyota OE bushings installed. The arms correct both caster and the positioning of the front axle.


Panhard rods (sometimes called lateral rods or track bars) are supplied with custom machined adjustable joints ensuring that the axle tracking can be dialed in 100% for each vehicle, no matter the lift height.

Vibrations are addressed by a double cardan front drive shaft to ensure smooth operation. The rear drive line angles are adjustable by using the rear adjustable upper control arms. In most cases the pinion can be rotated down to correct the rear drive line angle changes. In rare occasions, this is not possible and a rear double cardan shaft must be installed to ensure smooth drive line operation.

To prevent over stretching of the brake lines, a set of direct replacement Slee DOT approved lines are supplied. These lines come complete with clips, and feature a sheath covered woven steel braid. The lines are 4" longer than stock length.

The necessary drop brackets and spacers are supplied to return sway bar close to stock positions. Bump stop drop blocks are supplied to ensure that the supplied OME Nitrocharger Sport Series Shocks are not over compressed and damaged. The kit is supplied with longer direct bolt in OME shocks to ensure proper articulation. Slee Shocks can be substituted for additional performance.

1991-97 Land Cruiser / LX450
Slee 4" Lift Kit


The 4" lift kit was put together for people that want to run up to a 35" tire, have good handling yet still use the vehicle on a daily basis for commuting or long overland trips. The spring rates were chosen to give a stable on-road ride, even for heavily loaded trucks.

As with the 6" kit, the spring rates of the SOF4FM and SOF4RM springs are chosen for 250lbs additional weight on the front and 400 lbs in the rear.

This kit contains all of the same parts as the SOF 6" Kit, except the springs yield 4" lift.

Instead of the front control arms, this kit corrects the caster with the Slee Caster Plates. These plates provide caster correction by using the stock front control arms but rotating the mounting points. Minimal cutting is required to fit the plates and a small amount of welding is recommended on the fitment.
Slee has theirs published as:
Front SOF1227: EXT: 18.0" COMP: 12.5" (STROKE: 5.5")
Rear SOF1230: EXT: 25.2" COMP: 15.2" (STROKE: 10.0")

Shock specs & info

Screenshot_2017-12-09-11-36-31 (1).png

Shock manufacturers give specs without bushings & collars like pic above. You must add the height of the bushings & collars to get accurate mounting measurements.


1 bushing & 1 collar = approx. 1"


No coils sitting on stock bump stop info:

My compressed measurements for the shocks without coils sitting on OEM bumps measured from mount to mount (metal to metal) front is 18.5" & mount to eye bolt for rear is 16.5"

Collapsed shock minimum length question
Also here’s the rear axle sitting on bump stops +30mm (1.2”). Notice the coil bucket cushion touching at the same time. Take what you will from it.


OME shock length just doesn't make sense!


Both of my compressed measurements of the OME "L" shocks are 15.25"


(This is just a rule of thumb for bump stop spacing to protect longer shocks)

Since 1 bushing & 1 collar = approx. 1" you must add 1" to the shock on each stud end shocks.
The eye bolt end does not.
Plus add 1" for safety crush.

Look below, we have 15.25" OME L spec shock plus 2x1" plus 1" for crush = 18.25" mount to mount surface.
So from above we know the 80 series mount to mount measurement is 18.5" so the OME L shock below will fit without needing any bump stops.
So, now we know once a front shock specs out past 15.5" compressed it most likely will need a bump stop unless the manufacture gives a recomendation.
Does this help?

For the rear the 80 series mount to mount surface is 16.5" So a max spec shock length with out a bump stop is 14.5".
This is why a 15.25" rear OME L shock needs a minimum of .75" bump stop to protect it.

King 2.5 specs
Compiled 80 series suspension component spec thread... shocks, coils & more.
From @@Qball post
Won’t have my kings 2.5 3-4 inch lift shocks till next month but I finally was able to get some specs. They are NOT yet making 2.0 shocks for the 80 because the 80s are so heavy they don’t think 2.0 shocks will be sufficient at least not to their standard.

All kings current make are 2.5 with remote and the 2 models are with or with out compression adjust, I think the one with compression have additional feature of internal 1 inch bottom out bump assist. Both version have flutter valves to creat 2 zones/stages of damping. I didn’t find out about the bump assist or I would of coughed up the extra money for the adjustable version, maybe during my first rebuild. They are custom shock place so they can be order however valving you want and as many extra features as you want.

The King’s current 80 specific 2.5 shocks valving profile is developed on @@jtwopark 's 80, they had it for 2 months. So they definitely spent a lot of time refining valving for a heavy fully armored 80. They do have soft, medium and hard valving however to suit your needs, or just go full custom.

Kings 2.5 for 0-2 inch lift
Front 16.119 - 26.144
Rest 15.679 - 25.709

Kings 2.5 for 3-5 inch lift
#25001-351 Front 17.181 - 27.206
#25001-352 Rear 17.044 - 28.301

These are called the Active Offroad Bumpstops by Timbren.

Active Off-Road Bumpstops - Timbren Industries Inc. Suspension Products

The front ones are working well for me without modification. The rears come with a very tall steel tower. Proper height can vary from one truck to the next, but in checking for accurate height on my truck I removed ~1.75" from the tower to get them to the right height for my lift and 37's.
I take back the "no modification" comment. These come with a round cup that goes between the rubber bumpstop and the frame bracket. I trimmed the sides off the cups so that they don't make contact with the coils in the front and with the tire in the rear.

Good work Nugget! Might be cool to upload an image of individual rigs outfitted with each suspension setup so others can determine stance when considering options.

It's about time you did this!! haha
So those 2'' lifts don't require caster adjustment right?? From your experience (anyone) what 2" springs would you go for...light wheeling, not loaded up much

Some great info in here. I sent you some other info to add if interested. There’s a lot of decent springs out there (depending on setup) and it is unfortunate that not all supppliers provide rate information to the consumer.
