Lift and Shocks????
 
So from the little bit of info I got from the previous owner who said he thinks the lift is a "Rubicon" and that the springs and shocks are silver I assume it is a rubicon express. It is the standard kit using stock arms. As it has a T-case lowering kit I assumed it was the 3.5" kit and not the 2.5" kit.

So I recently bought some Rancho 9000's which are awesome. But first thing down the trail they bottomed out. We tightened them up and made it the rest of the day. The shocks I bought were for a 4" lift and I am worried that maybe I bought the wrong length shocks.

I did some measurements. As it sits, the front springs are 13.5-14" in length, and there is about 3.5" of upward travel left in the shock. The bumpstop is about 8".

The rear bumpstop is about 4.5" and is yellow in color.

If anyone has a 3.5 or 4" lift does this sound about right? Should the shocks have more upward travel than this, or are they meant to have more downward travel?

Are these aftermarket bumpstop lengths or did the installer not put on new ones?

What model number Rancho shocks did you buy? The number is stamped on the side.

I got the RS999255 in front and the RS999256 in the rear. I guess maybe I should have gone with the 2-3" lift versions which are RS999239 and RS999241.

Will take bump stop pics tonight if I get a chance.

Here is the Rancho Shock guide.... I use this whenever I have questions on shock length...

Here are some bumpstop pics. I also attached one where I am pointing to the top of the shock can.

Considering that's all the lift you think you have, yeah, that probably would have been the better idea.

But hey, in for a penny, in for a pound, right? Throw some coil spacers in there and make your setup an honest 4" lift, and you'll be good to go!

You definitely need bump stops or the 239/241 shocks. You are bottoming you shocks out. Rancho has 90 day ride and return policy so you can take them back.

and those bumpstops in the rear are stock...get a kit to extend them and that might be most of your battle.

This is the info I was looking for. Jeez, why go to all the trouble of installing new springs and not throw in new bumpstops while you are in there....

its not that you need new bumpstops, its that you need BUMPSTOP EXTENSIONS.

RS999255 Front shocks have a compressed length of 15.875", so you'll need about 2.5" front bumpstop extension.
RS999256 Rear shocks have a compressed length of 15.125", so you'll need about 3.25" of rear bumpstop extension.

I have been out looking for bumpstop extensions. As soon as I double check these suggestions against some measurements I will be ordering them.

If you have access to round stock... just make your own and get longer bolts. Not much to them really... here is a pic of the front extensions...
