Compiled 80 series suspension component spec thread... shocks, coils & more. (2 Viewers)

[GW Nugget]

J from @TRAIL TAILOR just replayed with these specs for the:
1" Tough Dog Suspension
Stock height coils are NLA, The 25mm is a more common item I usually stock.
1" Coils
FRONT:
TDC948SL ~ LH-480 RH-490 ~ (16.5 wire) ~ 200/250# ~10 wraps
REAR:
TDC949SL ~ LH-470 RH-490 ~ (17mm wire) ~ 220/280 ~ 8.8 wraps


Thanks J

With these free height they will be able to play with the low lift long shock theory I have.
​

 

[GW Nugget]

I have this thought to get the least amount of lift with the longest shock possible without the coils falling out.
For the longest time folks have been running the OME 850/860 with the longer L shock with much successes.
I ran 850/862+30mm coil spacer & L shocks for over a year without issues.

Lets starts with the specs:
2.5" lift OME 850 free height = 19.49/19.88" (220# rate)
2.5" lift OME 860 free height = 18.89/19.29" (220# rate)
L shocks are 26.5" extended
Above specs are the bar to compare to.
Below are coils with low lift that can run OME L shock equivalent length of 26.5".

Stock OEM
Shortest OEM stock front coil free height = 18.5" +25mm= 19.5" (170# rate) ~ 1" lift.
Shortest OEM stock rear coil free height = 18.5" +25mm= 19.5" (170# rate)~ 1" lift.

Old Man Emu
Stock height OME 861 free height = 18.89/19.29" +30mm= 20.07/20.47" (170/250# rate) ~ 1.5" lift.
Stock height OME 862 free height = 18.11/18.50" +25mm= 19.11/19.5" (170/260# rate) ~ 1.25" lift

Dobinson
Stock height Dobinson C59-210V free height = 18.7/19.09" +30mm= 19.88/20.27" (160/239# rate)
Stock height Dobinson C59-221V free height = 18.11/18.5" +25mm= 19.11/19.5" (160/239# rate)
40mm Dobinson C59-269V free height = 18.89/19.29" (160/239#)

Tough Dog
Stock height coils are NLA, The 25mm is a more common item I usually stock.
1" Front TDC948SL ~ 18.89/19.29 +15mm= 19.48/19.88" ~ 200/250# ~ 1.6" lift
1" Rear TDC949SL ~ 18.5/19.29" +10mm= 18.9/19.69" ~ 220/280 ~ 1.4" lift

~~~~~~
To sum it up you can run the longer 26.5" shocks that give more down travel for better traction off road with a little as 1" of lift.
As long as the front coil is at least 19.5" & rear is 18.9" the coils will stay retained.

In short you now have a choice of spring rates in a low lift long shock option.
Front:
170#
170/250#
160/239#
200/250#

Rear:
170#
170/260#
160/239#
220/280#​

I recently installed a Dobinsons C59-222/223V kit on my LX450. Now that I am looking at the info on page 1, this kit is listed as the "flexi 2". The FH on this is around 3.5" less than the 2/2.5" variable rate coils (C97-146/147VT) that use the same shock. This seems odd no? I did notice when installing the rears were actually shorter than the OEM coils..

 

[TYM4FUN]

For TJM, you listed that the 50mm progressives are a 2" lift, but the XGS 50mm (not progressive) I installed are a 4". I called and had a couple conversations with them before purchasing because the 50mm title didn't seem right?

Here are the part numbers I ordered at the time:

TJM 4" SPRINGS #770FRC480B, 770RRC480B
TJM XGS LONG TRAVEL SHOCKS #650GEL280B, 650GEL180B
TJM STEERING DAMPER #651048
TJM ADJ PANHARD RODS #658ADJPR008, 658ADJPR007

I have had the springs and shocks installed for 7 years and they have held up well to all the added weight while still providing 4" of lift.

Before and after TJM 4" lift pics with 285/70r17 and driven 4 miles to to settle the suspension and NO spring spacers....

Measurements before F-20 1/8" R-20 1/8"

Measurements after F-24 7/8" R-24 7/8"

(Measurements taken from center of axle hub to bottom of fender flare)

I use MM to Inches to convert Millimeters to Inches

 

[TYM4FUN]

I use

<a href="https://mm-in-inches.com">MM to Inches</a>

to convert Millimeters to Inches

The conversion is not the issue. It is how TJM lists some of there products.

The other day i had a rare opportunity to get under a stock 80 & saw some thing that came on like a light.
Looking at the rear bump stops & cone bumps the are same height.
So from now on i will be suggesting to lower the reat cone bumps the same as the frame bumps. Here is a pic.

I did lower my cone bumps, but didnt lower the same as frame bumps, because i didnt have the correct bolts.

 

[B Todd]

Has anyone ever tried a 2851 front and 2862 Rear + 1" spacer combo? Wondering if that might give a level stance for someone who has no weight other than spare tire in back.

If the cone bumpstop was simple to drop, we would all be doing it. Actually, the cone bumpstop should be an inch, or maybe more, closer to the axle because it’s the one that would touch and compress easing the impact that is felt when coming down in the frame stop abruptly.

My solution was to install bumpstops like these that offer some compression cushioning affect as the axle heads up toward full stop.

I did that combo, but had more stuff in back ... look at the 1st 3rd of my thread.

Hey ya’ll, I’ve been searching for a while but I haven’t found an answer. Do we agree that the factory 80 and 100 rear coils are essentially the same? I just find it really hard to believe Toyota would put the exact same springs under the heavier 100.
The eventual question I’m trying to answer is what will these old 1991 LC springs do in the back of my Sequoia for lift? I’ve heard that 100 springs net 2”, I’m hoping these will be an inch or less. If they are actually (tested?) identical to 100 springs I’ll just save myself the hassle and install some short spacers instead.

For an inch or less? A simple spacer will satisfy.

 

[GW Nugget]

80 to 100 series does fit, but what i see is different color dots. 80s are 2 pink 1 yellow & 2 green 1 green. Your coils are 2 white 1 blue & 2 green 1 orange. This would mean a different spring rate.

Doe anyone know what the spring rate of 100 series stock coils are? If answered, ill post on page #1.

@GTV will you give specs on those coils? Turns, thickness of wire & free height. Also a better picture.

Thank you for your time

The cone bump pad on the axle sets up higher on the axle so the cone bump does hit 1st...

Yes, I’m certain spacers will satisfy but I’ve got these in stock so I might as well try them out unless someone can verify that they will not give me what I’m after.

I’ll post specs later today.

You could probably try them out and then educate us.

So we agree then.....

Ok, so as I mentioned before these coils were recently removed from a 1991 80 series. The truck was purchased a few months ago in stock form by a buddy of mine. He lifted it and gave me the old springs.

Drivers side measures 18” tall (2 white, 1 blue), passenger side is 17 1/2“ (2 green, 1 orange). Both coils have about 6 1/4 turns and the wire diameter is about .605-.610” according to my calipers

I would expect that the 91 springs are lighter duty than 93 plus due to the later models having a full float rear axle assembly which can carry more weight.

Ok these are 3FE 80 series coils, i misunderstood the previuos post...
Well then just put spacers under your current set up.
