Upgrade
 

Consider GMRVUE SES kit. It replaces the bump stop with a rubber enhancement spring and claims better stability and capacity.

Hi there. I'm new to the forum and just reading through just familiarizing myself with stuff... But bumpers... There is something from the off-road world you could do if the metal parts are good. I ran a silverado like this for years.... Go buy a bunch of hockey pucks. Then use a hole saw to create disks the size of the I'd of your "cup" drill a hole down the center of them. Counter sink the top "puck" to accommodate the top of the bolt. Stack the pucks and bolt em down. If you have a bolt that goes up through them. I know guys who just welded a bolt in place and cut it off at the right height.
It seems sketchy. But off-road guys have been doing it for years. I did it to a pickup and it lasted prob 5 years till i changed over to air bags.

Just a thought.

Hockey pucks are pretty damn hard. I know. I've taken them in the shins.

I can see how off-road guys are not interested in the concept of comfort, but for a guy driving down the street, I would think it might be a bit spine rattling if one of the bumpers actually came into play with respect to stopping the motion.

But then again, I've never tried it.

On the subject of hockey pucks, they make similar shaped pucks out of hard rubber , with slots cut in them for stabilizing the pinch weld when you use a jack to lift up the car. The centers are mostly intact, and they would have some inherent give, being injection molded rubber that is more flexible than that used for hockey pucks. Just a thought.

Wasn't Don Rickles famous for calling people hockey pucks? LOL

Solution found...
 

For anyone who has the same problem, found for a work around using new parts for about $40.
Turns out 1997-2006 Jeep Wrangler CJ front bump stops use a similar style cup+foam stop, but the total assembly is about 3" too short. Also turns out that there are aftermarket bump stop extensions which mate with the original cups. They are polyurethane and much stiffer than foam, but the finished assembly with the extensions is 5.25" tall plus the bolt, which is only 0.25" shorter than the original. Also, the Wrangler CJ stops use the same bolt thread so the final product is a drop-in replacement.
Cup replacements are $13, and extension stops are $26. Part number for the cups is 52087635. The extensions I used were from Azumka. You can also buy the cups with the original yellow foam ($20) if you want softer (but shorter) stops.


I can post pictures later if it helps.

Thank you for providing a solution for our orphan vehicles. Much appreciated!
