    Comments about AutoCraft HD Rear Helper Spring:

    I solved the problem of lift in my minivan 2002 Town & Country with leaf tired. So now I can put my family and luggage to travel quietly.
    It supports the weight of people in the back seat and maintains regular lift.

    Not needed any extra adaptation for installation in my car.

        Comments about AutoCraft HD Rear Helper Spring:

        Site said this would fit my 1997 Ford Explorer XLT. While the springs fit beautifully, the U clamps were 1/2" too narrow and would not go around the axle. I had to buy a separate set of clamps to complete the job.

        It won't fix sagging springs but if your looking for a band aid until you can replace your worn out parts these will work to improve ride height

                Added to a 06 Silverado. I haul a lot of fire wood and other stuff. Add these to the back end of the leaf springs. They helped with the sagging and the truck handles much better. Keeps truck from rolling around turns. I would deffinatly recommend.

                      I'm glad to assist, Mike! This AutoCraft HD Rear Helper Spring (Part No. AC121500/12-150) is universal and not a vehicle specific. You would have to match one by size to what is on the vehicle that can be fabricated into its place. Its outside diameter is 4 inches and inside diameter is 3-1/8 inches. The bolts are 4 inches long and the U-bolts are 5.5 inches long and 3.25 inches wide at center. The overall length of the spring is 7.5 inches.
