can somebody please tell me what kind of bumpstops to get for my 97 xj with 3 inch RC with control arms and new rear springs. thanks for your help guys

 

Day star extended if you want to budget, speed-bumps if ya wanna get fancysmancy

 

daystar has two different kinds they have a 1.5 or a 2 inch, which one do I need for a 97 xj sport?

 

You need to measure for how much you need to bumpstop it. There is no specific amount bumpstops need to be extended for x amount of lift.
FWIW though, my fronts are extended 2", using hockey pucks inside the coils. Dont remember how much my rear bumpstops were extended before one of the brackets broke, I've gotta make some more for the rear. Thats at 1.5" lift with 33's, minimal trimming, and the tires didn't rub.
