Jacked up the front end of the dually (see sig) Saturday morning to change the oil before I park it in the barn for the winter. I guess I got some more maintenance to do.The driver's side front bumpstop fell out! It resembled a cube of stale sponge candy. Rotten after only 14 years... They don't make things to last anymore!!!Looks like it needs new shocks too.There's aftermarket/improved rear bumpstops for days... Is there anything for the front?

I replaced mine last year but after reading multiple forums it seemed the factory yellow progressive stops (aka jounce bumpers) were the favorites among users. I'm not sure if the 3500 uses the same jounce as the 2500 but the GM PN is 15835667. They can be found for about $20 each if you shop around.

Here is a manufacture who makes "better" replacements.
