2013 Chevy 2500HD. Installation is pretty straight forward on what to do. Pry out the old stops and press in the new ones. However it is difficult to press in this new stop. I tried oil and used jacks and blocks of wood to press them in but had a hard time getting them in. I ended up putting them in the best I could and hooking up my skid loader trailer and loading the skid loader on it to get enough weight to press them in. Once installed I loaded my skid loader and went to work, I was really impressed with how it road down on these overloads. Once the weight is off there is an inch gap between the axle and stop so your ride never changes with zero weight. Overall a great product, my truck doesn't squat anymore and I can haul heavy loads with a decent ride.

I couldn't see paying over $200 for these, so I went with the Chinese Timbrens. They seem solid. I installed using WD-40 and a pry bar. I used my travel trailer to raise the rear end up, and the weight of the trailer was good enough to press them in against the rear end. I did not use wooden blocks.

I have a 2021 Chevy Silverado 2500HD LT. I was a little skeptical of these just because the price is so substantially less expensive than their brand name counterparts but if you think about it… it’s just rubber. I was able to install both of these in about 45 minutes. Took me a few times to drop my truck on some 2x4’s underneath these bump stops to push them into the cup because these things are super heavy duty. Finally, I lowered my 5th wheel into the bed and they definitely got seated after that. Only 2 days prior, I replaced my absolute trash rancho shocks with some Bilstein 4600’s and it stiffened up my back end a lot and made the ride so much better. I figured I would put these on now that I know I’m not floating all over the place and after a test drive I couldn’t tell they were even on except maybe when I hit a speed bump. With bad shocks, you likely will feel it though. My truck still squats with the 5’er on but not nearly as much. Had to have saved me a good 2-3”… I forgot to measure and I’m not about to install these things again just to see but it’s noticeable. I have yet to tow, but we’ll see how it goes and I’ll report back if anything negative but I suspect these will really make it better. So far so good!UPDATE - 12/15/24 - Well, we took the 5’er on about a 4 hour drive from FL to New Orleans… I knew the roads west of AL were bad, but my god… especially in Louisiana the roads are an absolute nightmare. Anyway, to the bump stops… Wow! What a game changer. I could immediately feel these engaging within about 5 minutes of driving and its night and day difference. It made the trip there SO much smoother, although I will say that if you get into a bunch of bigger bumps, you can feel the rebound on these, however it is a much less puckered up feeling than without them. I ride substantially higher, the truck doesn’t look squatted really at all and just looks exactly how you’d want your truck to look with a massive load like I have… I’ve got about 3k in pin weight, and probably pulling around 14k or so gross. Anyway… I was highly impressed with these. I am tempted to still try the Roadmaster Active Suspension and swap back out with some smaller bump stops (don’t know that I’d ever use the OEM…) and see which I like better. The Roadmaster has a few things that I don’t think these really help with, like axle wrap and wheel hop and so forth, because these definitely still have some wheel hop just because the rebound is so strong. I feel like if they were the same size but rated more for like 4K, it would have been a perfect ride. Either way, these were great and substantially smoothed out what would have otherwise been a very sketchy ride. Totally worth the price to at least try these!

2013 Chevy Silverado, easy install, nice ride, I didn't know what the originals are like but for the price I'm sold. Trailer weight in photo 5,000#s with 6,000#s of trash in it

Easy to instal and they fit perfectly, but it absolutely made suspension solid. There is no spring action. Every bump was felt in the truck and the trailer I towed. I removed the Maxspeedingrods suspension and threw them away after 500 kilos. I am sure that every screw in my rv was hammered loose by the rock solid ride
