I put a "budget lift" in my '99 XJ. 2" spring spacers and with the kit came extended bump stops. I installed those as well. I thought it peculiar at the time, if I'm lifting the truck, why do I not want to replace the old bump stops? Doesnt that mean I'm not going to have anymore travel than when I started? Now when I'm hitting anything more than a roller, my bump stops are slamming into the frame, and chattering my teeth.
Anyone install a similar lift with the bump stops and have the same problem? what did you do? I can't go back to stock because I had to modify the post to install the new extended stop. Could I just cut it?

The bump stop its just doing its job, the only problem seems to be that you use a larger than lift bump stop , you either have two choices , or you get a higher lift or you just will have to cut the bump stop.

it happened to me once and i had to go taller that's it..

Hey guess off topic here sorry but honestly is it bad if you don't have bump stops?
like what's the worst that could happen

I guess other than limiting uptravel they're a kind of fail-safe for suspensions to help against spring damage due to an overload on the spring (suspension bottom-out)

They also keep you from damaging your shocks, springs, and they keep the diffs out of the body and oil pan.

I just hacked about 2" off the bottom of the bump stop very carefully with the sawzall between the coils. Worked great, the toughest part was trying to get the hacked off chunk of rubber out of the inside of the coil. Took a little prying with the jack handle to spread the coils, but it's all good now.

I don't have mine I ripped em off when I went wheelin a while back

Overall , limiting uptravel , damage to the shock , spring , and oil pan, basically thats their job , but you wont have any trouble if you have a 4 up lift ...

Negative. Bump stops are relative to tire size.

The factory stop is sized so that you prevent the ~27" tire from contacting the inner fender. When you lift a vehicle, you typically pair that with larger tires. THAT is where the conflict happens. Lifting a vehicle does not allow you to move the axle higher in compression.

Its a simple concept guys, don't post misinformation. You NEED them done correctly; bottom line.

Edit:

(where is the facepalm smilie when you need it)

completely incorrect. It has EVERYTHING to do with tire size; that's it.

preppye

what you said is completely right , it also has to do with tire sizes , but remember that the more turns the coil spring have the stiffer it will be to compress them , and the larger the travel the harder will be to the tire to hit the fender (if its not cut ).

Bossokee

Yes, also more turns in a coil makes the compressed length longer, requiring longer bumpstops to compensate. This way the you wont have to worry about the coil being completely compressed which isnt good for it. Usually the tire would hit the fender before this though, which is even more of a problem

Agree!!
