These are great keeps my truck level both loaded and unloaded more control while pulling a horse trailer. SD Truck Springs has great pricing and easy to follow installation instructions will use them in the future for all my truck needs
We loved the Helper Springs part # 987 that we used on our Chevy 1500 in May to tow our 30' sailboat from North Florida to Homestead for a trip to the Bahamas. Would hate to think what the ride would have been like without them. Thanks again SD Truck Springs
Good quality but a little bit of a tight fit with the plastic fenderwells hanging down from the bed. Installed pretty easily
Great product but they are a little noisy next time I would step up to the next model which are are quieter. Handles the trailer a lot better and very easy install
Great product, I can haul a pallet of water 2000 Lbs yet the truck height isn't to high when empty,
I added these springs to my 1/2 ton 2011, Crew Cab, 2 wheel drive, Chevrolet Silverado. I also added a fifth wheel to my truck and have been pulling around a 32 foot fifth wheel travel trailer with no problems. I will say that my motor, gearing, and tranny aren't equipped to haul a 10,000 lb trailer but my suspension sure is. As a matter of fact the camper sits better on my truck then it does my fathers F-250. Easy install and they look good too.
