1997 Jeep TJ Bump Stop Mod

So i got a 3.25″ lift from rough country for my 1997 Jeep TJ Wrangler. As I was installing the kit i noticed that the rear didn’t have bump stops cups! But I was in a hurry to get it done, i had to drive it to work the next day. So i opted to come back to it another day.

That day has come…..

Now because i was missing the cups in the rear, i had to fab something. I did some digging and saw people using hockey pucks. I thought that was a great idea….but i was still missing the cups.

So i bought polyurethane “short” bump stops and decided to just add on to it to make it work for me. Still needed to add some beef to it, i used hockey pucks as spacers, and long bolts, to make the assembly longer.

Now the diameter of the puck was too large for the top of the coil spring. I used my CNC machine to mill out a 2″ round chunk with a hole in it. I quite possibly could have used a 2″ hold saw. But it would have made a BIG mess, been ugly and quite frankly it would not have even been notable here. My CNC machine used a single flute carbide bit, and cut through the puck like it was butter!

Pucks: $1 ea
Bump Stops: $13 pair
Hardware: $3-ish
