Rated 4 out of 5 by from 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.
