Sulastic Shock Absorber Shackles for REAR Leaf Spring Suspension model SA-06 - Compatible with 1980-2016 Ford F-250 ; 2011-2023 Chevrolet/GMC Silverado/Sierra 2500HD, 1992-2016 E-350

These are an absolute game changer! They seem a little pricey but believe me they are worth every penny. These were my 2nd set.Installation is a little difficult without a lift but my daughter helped me and it was 3 hours.GMC 2025 AT4x HD 2500.

Without a lift or high (tall) jackstands, the install was an absolute bitch and a half. But I stuck with it because of the payoff.Took a good day of working on it to get my parts out, grind a little metal to encourage the spring to seat and then pay attention to the number of washers and orientation when putting the new ones in.With all of that said, I've definitively felt a softer ride in my 2500.I take bumps smoother and the road is a little kinder now.Also did Fox 2.0 all the way around afterwards, and I ride like a new 1500 now.Very satisfied. Let's hope they last a while.

Installed on a 2005 F250 4WD standard cab. Truck rode terrible before the install. No noticeable improvement after the install. Tried adding an additional 325 lbs of wight in the bed to improve ride.After the install the truck was all over the road with rear end sway. Once removed drive ability improved.A waste of money now sitting in a box on the parts shelf.

Probably most noticeable upgrade I’ve ever put on a truck! Absolutely gave it a better ride!

Very easy install, with simple hand tools it only took me about 2 hours from start to finish. You do need to raise the bed about an inch and a half to get the bolts out of the springs but it is simple. I have a 2016 crew cab 4X4 Duramax. Day and night difference in ride quality. My only regret is that I didn't do this sooner.

These are great, takes the harsh jolts out of the rear springs, makes the ride like a 1500. Best thing I've added to my truck. Will provide updates in 6 months for how they hold up. So far, so good!!

Very noticeable difference in suspension smoother ride. These do settle after time I had also bought the lowering kit for a nice stance but after 6 month I started to hear a squeak turns out my truck bed was rubbing on the leaf spring caused by the shackles reduced compression. I removed the lowering kit adapters the company also provides and there was actual wear and metal shavings from my truck bed. I own a 2015 GMC and do not recommend purchasing the lowering kit adapters, not sure how long these shackles will survive since I already experienced decompression. As of now the ride is still very smooth (w/o lowering kit ).

Got it for my f350 diesel. It helped with a smother ride! I didn't tell friends that I installed it, and I asked them if the truck felt different. They said it is allot smoother.
