I'm currently doing up my old XJ, improving on it as a 4wd camper. As part of the renovation I've put in a 2" coil space and extended shackle lift which I need to get certified sometime. I spoke to a certifier a couple of weeks ago and he mentioned that the bump stops will need to be extended to pass. For the rear I have done this by adding some RHS steel between the stops and the chassis. But am unsure about what to do with the front.
I have been unable to find commercial extenders and everywhere I have searched recommends gluing 3" dia rubber on top of the coil spring seat as done here: http://go.jeep-xj.info/HowtoBumpstops.htm. I have done this by cutting a rubber mallet to size and gluing in with urethane sealant. Its solid as and the only way it is going to come loose is with a hammer and chisel, but I'm worried that the LVV certifiers won't think its good enough.
Have any of you guys done this and passed? Or is there an alternative method that is acceptable to the lvv?
Bump stop extensions
Re: Bump stop extensions
If you are only lifting 2" with a coil spacer and an extended shackle do you really need to bother with certification ? Upcountry Xjs came out stock with 1" more lift
You can attach a spacer on to the coil spring base by counter sinking a bolt thru the spacer and taping a thread into the coil spring base

Re: Bump stop extensions
Wouldnt even bother with certification. LVVC regs are on here someplace, but in short, as long as your springs and shocks remain in unmodified factory fittings, then its cool. You get into issues where the steering components have to be modified to accommodate high lifts. as soon as the steerin components are changes, a cert is needed, and with a 2 inch lift, your sweet. Ive lifted one cherokee to 2 inches and one to 3 inches and had no issues with steering geometry. I dont know anything about extended shackles though, that may be another kettle of fish, Ive not had any experience with them.
To follow on from shoes comment, our XJ sports are 1 inch higher from factory than our XJ Limited's. Not sure how the upcountry specs were applied in NZ.
try "justjeep" on trademe, he can sort you out with some rugged ridge or skyjacker extended bumpstops im sure....

Re: Bump stop extensions
Thanks guys. I didn't think it would need one either but I asked the WOF guy and he said he wouldn't pass it without a cert. Then asked a LVV guy who said "Yup it needs it" so probably should get it certified. Of course I could always find an easier WOF guy! (my normal one is a tough one).
Mines a '94 SE so no factory lift like the Sport or Upcountry unfortunately. From what I gather it the certification is needed because there has been a modification to the suspension mounts. If I had just changed the leaf and coil springs I probably could have got away with it. I made the mistake of not finding out the cert requirements before putting in the lift.
But despite the urge to drive over the top of boy racer cars, with the new shocks and lift the Jeep drives better then it ever has. I haven't taken it off road yet but on road it is noticeable improvement. "Justjeep" has done me well for parts so far but his catalogue doesn't list bump stop extensions even though the instructions in the Sky Jacker kit mentions them. I was thinking of Shoe's suggestion of drilling and screwing into the coil mounts but want to avoid having to remove the coils again if at all possible.
