Rated 4 out of 5 by They helped a little I tried this before getting new leaf springs for my camaro. They help but i still get a sag. August 21, 2016
Rated 4 out of 5 by useful Ok so the 2,000 lb is a stretch. You're not going to change a 1500 into a 3500 for 50 bucks. They are great for bringing life back to my 24 year old springs. I installed them by myself in about 3 hours, even though the instructions were less than helpful for my truck. July 17, 2016
