Bilstein 24-196468 24-253161 Set of Front & Rear Monotube Shocks fits 2011 2024 Silverado Sierra 2500 3500 HD with 1.5" Front Lift & 0-1" Rear Lift

Left front is the most difficult, 21 mm wrench and socket , then a 3/4 wrench and socket.

The shocks were a great fit for my 2015 Duramax GMC truck! The difference in the ride was more than I had hoped for, it rode so smooth compared to the old shocks. I would recommend these to anyone looking for a better ride!

I have a 2018 Denali HD 3500 SRW short bed with a 60 gallon aux tank in the bed, airlift bags in the back... That being said, I have a 24' pontoon boat, a 24' enclosed trailer for my RZR/ATV, an open deck car hauler, 30' bumper pull toy hauler, and an equipment trailer. I tow a lot. My truck pretty much always has a trailer on it or a couple thousand lbs payload of fuel and stuff/tools. The truck came with the Rancho deals and has ~70k miles. I proactively swapped these in because the old shocks were irritating and ride was fading.So install was a breeze. You need a pair of 21mm to take all of the factory stuff off and a 19mm or 3/4" to put the new fronts on. Install was for me, very very straightforward. Everything was very easy to access. The old shocks had ZERO signs of not being any good. They pressed out when unbolted, no leaks, no holes in the body, etc.Once they were installed, there seemed to be a bit more initial jounce/harshness, but it's just a more precise road feel which was nice in hindsight. The ride is more consistent and precise than the old shocks. These trucks just do not have much up-travel in the back. Speed bumps can find the bump stops pretty easily in the stock Rancho configuration, but the new setup has a much more progressive valving, which alleviated this issue for me. As the suspension compresses, there is more resistive force applied. The old shocks feel like there's a set valve rate and it just does it's consistent thing. These ones apply more valve as they stroke through the motion. This feeling is VERY comforting while towing the boat because the tongue tries to fly around. The new shocks bring the boat trailer under control where bouncing turns used to be pretty wild. I've not put the heavy (10k+) trailers on yet so no feedback on those, but those are usually tamed not by shocks, but more around the bags. The big trailer runs 40-60PSI in the bags which takes away all of the bounce. I will update the review if the heavy trailers change anything.All in all in summary, these shocks might not be worth the extra $ over anything else, but they're really good. There's no stunning-remarkable difference from the factory Rancho shocks I took off, but they seem more stable, better light-feel, better jounce control, better compression progressive control.

Great service and product

Being the owner of a Silverado 2500 HD, I upgraded the tires and wheels, and did a leveling kit. The shocks that came with the kit were "ok". I had researched Bilstein 5100 series and made the decision to buy all 4. What a difference! Install took me about an hour, and the first test drive was such an improvement. No more sloppy bounce and the ride was back to normal. I run 35x12.50-18 tires so the unsprung weight is significant. They are no problem for the 5100's. Just get some and forget the others!

Fits a 2025 Silverado / Sierra 2500 perfectly. Highly recommend over stock for a much smoother ride.

Product showed up missing nuts for one of the front shocks, boxes were also open when they arrived. I’m sure the shocks themselves are great but I wouldn’t order them from here.

They have improved the ride immensely towing 18k and a pin weight of 3800lbs.Yes, I'm running AirRide 5000lb bags as well set to 20psi.
