Rear bump stop extension

[LucasD]

I am putting on my rro lift. Its the spacer lift in the rear. Ive seen people put hockey pucks as new bump pads with a spring lift, but I was wondering what people do on the spacer lift like this?

I was thinking about taking it back apart and welding a plate over the top of the spacer for a bump pad. Is there a better way to go about this? Thanks

Most of us drill a hole in the lower spring perch and stack hockey pucks there, bolted down. A rule of thumb is one puck per inch of lift, because regulation pucks are an inch tall. You wouldn’t have to weld anything if the diameter of a hockey puck fits inside that hole in your spacer.

Seems strange RRO wouldn't address the bumpstop issue in the design of the spacer - would be so easy to make that solid instead of hollow like it is. I think welding a plate on top of the spacer would probably work fine (if it's cast iron that might be a challenge). Another idea might be to fill that cavity with polyurethane sealant - you could do that without having to disassemble anything although it would take a few days to fully set up. The 3M Window weld stuff sets up faster and harder than standard polyurethane sealant so might be better, but it's a bit more expensive.

I like trailer door bumpers https://www.ebay.com/itm/144017104850 better than hockey pucks - they're cheaper and the "countersunk" depression for the attaching bolt means your upper bumpstop isn't getting damaged on the head of the bolt when you bottom out. If you need more height than one bumper provides I guess you could stack them but probably better to have a hockey puck on the bottom and a bumper on the top.

I used hockey pucks with a similar spacer. They have a friction fit and I didn’t have to drill or bolt anything.

Do you actually use vulcanized rubber hockey pucks or is that just a name to reference something else? I don't know so I am asking out of curiosity!

It's actual standard regulation hockey pucks folks use.

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:

1. 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.)
2. I drilled a single hole right through the center of the lower axle spring plate (the metal cup).
3. 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..

I think I got a pack of six generic hockey pucks on amazon
