I ran into this exact same issue with my rear spacer lift!
Instead of stacking hard hockey pucks like everyone says, I found a much easier way. I bought a set of
Yukauto Polyurethane Rear Bump Stops for Ford F250 trucks on Amazon. They worked perfectly.
Here is what I did to make them work:
- I used a saw to cut top part of the new polyurethane bump stop. This leaves a wide, flat landing pad. (My spacers are 1.5 inch so if yours are 2 inch you would not need to do this.)
- I drilled a single hole right through the center of the lower axle spring plate (the metal cup).
- I bolted the new polyurethane bump stop directly onto the plate using a single bolt.
Because it is made of hard polyurethane, it can squash down a little to soften the blow if you hit a massive bump. Now, when the suspension compresses, your upper yellow factory bump stop hits a wide, flat pad on the bottom instead of going through the empty spacer hole and bottoming out your shocks! It keeps your factory rubber spring isolator quiet and runs flawlessly.
I actually have multiple Jeep Liberties in the family. We tried the standard puck setup on one of them, but I wanted a cleaner, more factory-finished look for this build. This polyurethane setup blends right in and looks great once it is bolted down..
