Help for tired springs

I have a 1998 Jeep Cherokee with 53K miles, but tired rear springs. These helper springs are an easy fix.

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.

I've used these before on another truck. They are great. They not only help with weight bearing but it improves the ride even when truck is empty.

    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.

            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.

            installed quickly by lifting the truck up and installing over the bump stops, U bolts needed to be about 1/2" bigger but I just forced them over the axle. It makes your truck ride a little rougher when unloaded but helps when loaded.

                      No, these will only raise 1-2 inches.
                       Call a Jeep dealership by you. (I tried calling, but since the weekend, there's only 1 guy and he's busy.)That'd be your best bet, though.

                      Glad to assist, Ron! You need to jack the truck up by the frame on each side to make room to install the springs between the axle and the frame and make sure you do not leave the steel brake lines underneath the u-bolts.
