I waited a long time before purchasing these because I didn't want my front end to be too stiff. These are quite the opposite. Now on bumps I used to wince before hitting, the front stays composed and settles quickly. I run Bilstein 5100 on the truck, and it did have a smooth ride, but some bumps on these trucks, you just feel. This greatly reduces that jarring, reduces roll during turning, and quieted down some front end noises I just couldn't figure out.

These work great. Really help with sway with a camper on truck corners and handles better.

Product shipped fast and was extreamly easy to install. The springs came with great instructions and was a perfect upgrade to the front suspension to my truck. I have an 8 ft HD fisher plow on the vehicle and with these springs installed the nose of the truck only dropped about 3/4 of an inch (a great deal better than the 3 1/2 to 4 inches it used to drop). It does ride a bit stiffer than stock but not bad enough that I would want to remove them for spring and summer. These springs let me keep the 285/75/16's on my sierra without any rubbing when the plow is up. Would deffinetly reccomend these to anyone with these trucks that plow or have any sort of aftermarket winch bumper set up.

They look solid but time will tell. These trucks eat these up every couple of years.

Never would I have ever imagined that such a small part could make us such a big difference on my 2500 HD ride quality. no exaggeration makes it ride as smooth as my Trailblazer. I immediately ordered them for the rear.

Since the OEM ones literally crumbled away, I decided to give these a shot. They are paired with Fox OEM Reservoir shocks and a 4" rancho lift with 315/75/17 tires and so far I've put about 1000 miles on them. I can certainly feel a difference in the way the front of the truck rides, it's smoother and more controlled. Shocks and bumps went on at the same time though, so I can't say it was one or the other. So far so good

Old ones were the factory bump stops and were extremely wore out was concerned of fit with the lift on my truck. I will say amazing difference helped reduced a lot of the issues with the truck hitting so hard on the smallest of bumps and dips. checked it after install and with the lift they are close with the LCA's well worth the cost
