so about 8 months ago i bought 4 Rancho rx9000 xl's, i bought them through 4wheelparts, all of this was in Austin, TX. Now i am in Montana going to school and my buddy and i were looking under my truck and i saw something very odd

The piston of the shock has come out of the shock tube and is doing nothing.

I am very confused by this because the truck has not changed its level or anything, why has it not changed? is there coils on the front end?

I'm calling rancho tomorrow and if they dont send me a new shock, im going to raise hell, this is a serious safety issue.

i will put a picture on my profile

Thanks

rancho should have the life time warranty, i had two of them blow out on me and rancho replaced them no problem

 

do you have any idea why they blew out? the only thing that i have done in the last month or so is been driving up this road filled with potholes to go skiing twice a week

 

either the shock is defective or you hit a very big hole which caused the shock to "top out" very hard. the reason it still sits at the same height is because the torsion bars are your springs. Shocks do not affect ride height.

 

well does this happen often? on theses types of shocks, i would expect them to not do this

 

its definatly not common, do they have a warranty? if so use it.

 

im pretty sure they do, it hasnt even been a year so they have to replace it, if not, im gonna raise hell and i know for a fact now that i am going to buy a procomp lift after this

 

Rancho RS9000s have a lifetime warranty, so you shouldn't have any trouble getting a replacement part. You can either go through the shop that sold your shocks to you or to Rancho directly, their # is 734-384-7898.

 

under carriage of the truck looks pretty muddy. were you four wheeling?

oaw

 

last time i bought a pair they had lifetime warranty, and mine blew out cause they were on a expedition that was constantly be loaded very heavy, even then they made it to 50k miles or more

 

that mud was just from driving up to the local ski area. i have only really carried one heavy load but it was fine after that, but these shouldn't be blowing out like this

 

There must have been some extreme flex of your suspension that ripped the shaft outa the body. That probably means the shocks aren’t long enough for the amount of travel you have. Lift the truck up with no shock on. Measure between the two mounting surfaces for the shock, that is your extended length. The shock will need to be atleast that long or you will "top out" as was previously mentioned. Also compress the suspension to get the compressed distance so that they aren’t too long.

 

Obviously they pulled apart, probably from being over-extended. Are your torsion bars cranked? Because that will cause the suspension to top out very hard. The shocks could also be the wrong part # (too short).

 

well i was told they were the right ones for my truck but obviously 4 wheel parts doesnt know what my truck needs

 

Wow!! I've never seen that.
