AOR Timbren Active Off Road Bump Springs for my 80 series Lx450

 Hello all, as you know I have been on a Low Lift/Big Tire phase with my 80 series Lx450.
To run a low lift with big tires I realized the sacrifice is up travel. The Lx450 has been running with approx. 3 to 4" of up travel which leads to hitting the bump stops on a normal basis. After a while it gets annoying though, the remedy is a bump stop upgrade. I decided to go with the Timbren AOR bump spring. I found a front set for $225 from Just Differentials, it took 8 weeks to get here, then found out they sent the "SES" version which are stiffer. I did try them out & they are a bit firmer than I wanted (SES is for constant load bearing). This sent me into a research frenzy. After few days research I learned what I needed to make a better choice on the next purchase. The current retail price for the Timbren AOR spring with brackets are $297...yeah, UGG.
 Through my online forum I learned about how much they compress etc... I decided I could DIY the rear brackets myself with 2" square tube & purchase the AEON spring separately for $99 per pair. The front bracket are offset, but still can be done DIY with 1.5"x3" square tube. 
Now you know the story here are a few of the specs with pictures.
The normal AOR spring from Timbren for the 80 series comes is an A515-55 which in a nut shell is 3.75" tall & compresses down to 1.5" tall. It has a total load capacity of 2,400#
The SES AEON spring that came to me has an A515-65 with same height & compression specs but with a firmer 4,000# capacity. 
After doing the research I decided to go with 2 sets of the A530-55 AEON springs that are taller with more travel. They are 4.75" tall with .5" more travel at 2.75" & compress down to 2" the load cap. is 2.800# (taller & more travel means MoBetter)
Here are some pictures.
The bump needs to go forward a bit more.
We as in me, myself & I need to do a we bit of grinding.


The A530-55s bolted on the 2" square tube.

I was going to mount them like this, but was able to get them further forward with the other brackets.

My axle is 1" further forward than stock, so I drilled a hole 1/2" forward & it landed dead center on the axle. I did grind on the passenger bracket to prevent coil rub, no coil rub so far.

39x12.5r17 Kanata Mud Hogs

In 2022, I did not have these yet, but I did get a set in 2024 here are some pics.





























 

Low Lift, Big Tires on a fzj 80 series is equals 2 to 3" of up-travel. (38"s, 39"s, 40"s)



A few years back I played a game to see just how low I could go with 37s on a 80 series. I learned a lot & will share it with you today. 37s will fit with 1" suspension & 1" body lift with 1" front/1.5" rear lowered bump stops. 
(If you have a 2" suspension lift then run 2"front/2.5" rear bump stops). 

When I fitted 38s on a 2" suspension/1"body lift, I used 1" front/2.5" rear bump stops after moving the axle forward 1". 

Just to note: the starting point...stock front up travel including compression is 3" the rear is 4.5".
Front bump stop gap is 50mm/2" for fzj80 series.
Rear bumps are hard... maybe .5" of crush if hit hard enough. 
Fronts crush 1.5 if jumping.
So under normal conditions if you add the 2" of up-travel plus 1" of crush the normal 80 series has 3" of up-travel in the front.

Now you know the spec, here are some 80s I found on the WWW.

@joez  3.5" lift
@Expo max has 4" total lift in the pic.
This rig lost a lot of weight so his up travel is more than stock.
