For stock rear frame bump stops, I conservatively recommend to lower bumps 1.5" for 35s & 2.5" for 37s.
Also knowing a stock frame bump will be approx. 2.5" tall when compressed.
We also now know how tall the Timbren AOR bump stop is when compressed is 1.5" compressed.
Now we do simple math... for the AOR bump stop to equal the OE stock bump would need a bracket 1" tall.
I know the 80 series front AOR bracket is 1.25" tall.
@Shoredreamer how tall is the Timbren 100 series rear bracket. (looks like 1.5" to me)
I got Timbrens on my 470. I can measure tonight if Shore doesn’t respond first.

This gets back at my original post. Stock rear bump stops are not all the same height. One appears to be about .75" longer

Can we all assume the 91-92 is different from 93-97.
When I make statements about bump stops I am referring to the 1FZ-FE fzj80 series suspension.
Pic below suggest the 3FE crowd is different to the 1FZ-FE crowd.
I would guess the bump stops were taller in the rear...
What is heavier a 3-FE or a 1FZ-FE?

Looks like the 100 rear Timbren is also 1.25” (def not 1.5”) and about 5” altogether (metal bracket and rubber bump). I got the Timbrens from Nitro Gear Just Differentials 2 years ago for reference. Sorry pics aren’t great and tape measure slipped (the tip is actually slightly above the bottom of the vehicle’s frame).

Does anyone have any direct comparison between the 70series bumpstops and the timbren's? 70 series bumpstops are longer and should have more compaction resulting in a softer "bump" than the stock bumpstops. The timbrens look to be an awesome solution but there's a $136 difference between the two solutions $89 (partsouq) vs $225 (just differentials).

Found a pair of 70 series bumpstops for $66 and bought them.
 
Please report back fitment and functionality.
These are 79 series.
Fitment & functionality... The holes have to be notched out & bolt hang on half way, advise a large washer to sandwich them. They are softer then stock, but not much though. They do stop 1" more than stock. The shims are .25" each... so your looking at 1.5" taller than stock set up in the picture.

Thanks! I figured with the physically taller block of rubber, they would be more forgiving that stock. I actually want the taller bumpstop since my factory bumpstops are spaced too far down at the moment and limit my travel.

Great, thank you. This is all is going into the Compiled suspension thread ASAP.
Sad thing is Timbren AOR bumps are going up to $297


Sidebar question, as I dig deeper on these Timbren AOR & SES rubber springs, I'm learning there are a bunch of sizes they have with different load capacities.
My question is when hitting pot holes, going through very rough
terrain to absolute hitting a wash out to catching a few inches to feet of airtime... how many pounds of force do you think is pounding a bump stop. If an 80 series is 6000lbs then divide by 4 equals 1500lbs per corner just sitting under it own weight then hitting something at speed would be 6K-10K range.

So, @Shoredreamer @Box Rocket @woody & whoever has the 80/100 series Timbren bump/springs, have you ever hit anything hard enough & think that those bumps could be a bit firmer or do you think Timbren "Nailed it" with the correct bump/spring rate for the 80 series with the A515-55 2,400# AOR bump/spring?
I have 2 sets of 2,400# AOR on order... found them on the cheap before they went past the $300 per price point.

Kong extreme are about 5in extended after mounting. There are other sizes of kongs also.

The base extension can be made at any size mine are at 2in.

You can also buy a pair for $32 Amazon prime.


I also have bump stop extensions for any other bump stops, these are also stackable.

I’m seeing 3 options for our 80s, maybe more, on the rear axle department with Timbren Aeon springs

ABSTORLC1, Active Off-Road bumpstop with the super tall metal tower and additional metal cup, using the A515-55 spring, 2,400# bump capacity

TORLC1, SES (towing application) with super tall metal tower, using the A535-65 spring, 6,500# bump capacity

TORSEQ, 100 series rear SES (towing app) with short metal tower, using the A550-65 spring, 11,500# bump capacity

Not sure how this translates into function exactly, other than the fact that the TORSEQ seems like it can take a harder hit than the AOR bump TORLC1.

Yep & to add, these are the bolt on non welding "KIT" options:
FRONT:
80 series front AOR #ABSTOFLC1A uses a A00515-55P30 - 2,400 lbs. AEON spring.
80 series front SES #TOFLC1A uses a A00515-65P30 - 4,000 lbs. AEON spring.
REAR:
100 series rear AOR #ABSTORSEQ uses a #A00515-55F60 - 2,400 lbs. AEON spring.
100 series rear SES #TORSEQ uses #A550-65 spring, 11,500# bump capacity AEON spring.

I asked this question earlier... maybe you all missed it. Calling on @Shoredreamer @woody @Box Rocket @Kabanstva or whoever.
 
Installed some Timbren bumps (100 series version) to my existing 2" bump stop spacers. Left out the circular isolator plate due to the clearance with coils. I may consider changing out the spacer with a 1.5" but I'll test this for now. These will easily compress under pressure.

So you must have the Active Bumpstop model ABSTORSEQ if yours compress easily and yours came with the steel cup. Have you gotten to try them out much? Is the softer rubber and compression hood for your setup?

I have pretty much the same spacing setup but I’m on their harder rubber TORSEQ model. I have a very heavy 80 so it’s working great for me.

Slight diversion off topic, but who are those turn-buckle style sway bar links made by. Much neater solution than what I have for lifted trucks.
Timbrens on the rear for me as well. Pretty sure I took the idea from @Corbet :cheers:Used the 100 series model and spaced it down with @Hitit66 frame bump spacer. Matches well with the 17.5” compressed shocks and 35s I run. The Timbrens basically are replacing both the stock frame bump and coil bumper. Waiting to get the Dobinsons rear hydro bumps when they are available.

LCP @ LandcruiserPhil makes those & they are very nice addition to the rear swaybar.
