Acdelco Specialty 519-30 Rear Spring Assisted Shock Absorber

Pour gmc sierra bien satisfait

Quality part. Installs just like a regular shock. It is a REAL coilover that uses factory mounts. Dampens very well in my 2006 GMC Sierra Ex. Cab 2wd. These coilovers are fairly large in diameter. If you have 2.5in dual tail pipes like I do, it is a VERY close fit depending on how your pipes are bent. Looks custom. I run BFGoodrich All Terrain ko2's in 270/70/r17 on stock 17in wheels. I run a Rough Country leveling kit, shocks, and springs up front. I run these coilovers on the rear. The ride is FANTASTIC. SO STABLE in the rain, dirt, and on the terrible streets where I live. Like its on rails. Super stable. Me and my family feel safe in all weather conditions. Great upgrade for any GM truck.

They were not the easiest to install BUT with some ingenuity, I was able to get them on. The shock along with the spring are pretty stiff so they were hard to compress enough to get the bottom bolt in. All in all though, they are WELL worth the price and installation time. They look good and raised my truck, about 1.5 to 2 inches..

2011 GMC Sierra reg cab LB 4x4, I used Readylift 3” rear lift kit 66-3003 and AC Delco519-30 rear coil over shocks.Use 22 mm deep socket. Everything fit good. Ride is excellent. Would buy both again.

Excellent looking shock! Ride quality is excellent. Will update ina few weeks on how they handle pulling a camper. I have a 2014 Chevy Silverado Z71 with the rocky ridge altitude package that has a 6 inch fabtech lift. These shocks are 24.5 inches from eye center to eye center so anything with more than a 3 inch lift will require shock extenders.
