Bump Stops are a critical part of your vehicle's suspension - they prevent damaging over-compression and eliminate harsh bottoming of the suspension. Daystar's Bump Stops are designed and tested under the most rigorous conditions imaginable to deliver positive stopping power without deflecting.
I did a 4 link in the rear of an XJ with coils and in the initial build I used a short 2" bump stop with a 3/8" studs. To use the full travel of the shocks I needed longer bumps. I found these, and although 4WP doesn't list the size of the stud, other sources showed it to be 3/8". They turned out to be 7/16" so they obviously wouldn't fit. I ended up pressing out the 7/16" stud and replaced it with a 3/8 bolt with a 1/2" nut welded on the bolt to prevent it from spinning in the bump. I then pressed the modified bolt into the bump and it works fine.

Great TJ replacement bump stop
I installed these on my 2000 Tj. I removed the rear tires, one end of the trackbar, bottom shock bolts and lifted my jeep up from the rear bumper to remove the coil springs. You might also need to remove the back end of your rear drive shaft for more flex and mabye one end of your control arms.To remove the stock bump stop just wrap your hands around it and work it back and forth while pulling down and it comes out, its pressed in. Remove the bolt that is in the center of the cup. I put a light coat of lube on the new bump stop around the top edge to make it easier to install and get the bolt started in the threads. I then used a pipe wrench on the metal part to get it snug.

Didn't fit 93XJ
According to the Daystar info it was supposed to fit an XJ also. Maybe a later model, but not a 93. I machined them down to fit in the 93 XJ with a mini lathe.

They just work
Great fit, can be trimmed for smaller lifts, so far they are standing up to some pretty good abuse. Installed in my 04 Rubicon with a three inch lift. Trimmed about 1 1/2 inches off with no adverse effects. Would purchase again.

Fit the stock, front bumpstop cups perfectly on my 2008 Dodge Ram 3500 4x4.

Look good, work good
These are high quality pieces, look good, and work as intended. My only beef is that they are difficult to install, they are hard to press into the cups! I used a floor jack to bottom out the suspension and push them in. I suppose they have to be stiff so they won't squirm out of the cups. They work as intended, and could be cut if you wanted a little more travel.
