F250/F350 Rear 2" Leaf Spring Lowering Shackle Kit (1987-98)

Still the most popular way to get rid of that “stink bug look” trucks have from the factory. Drop Shackles have been around since the beginning of sport trucks and still rule if you just want to get that rear end down. 2″is the typical drop and that's exactly what you get on your F250/F350 with these DJM Shackles.

JACKING, SUPPORTING AND PREPARING THE VEHICLE

1. Open the hardware kit and remove all of the contents. Refer to the part list (Page 3) to verify that all
parts are present.
2. Park the vehicle on a smooth, level concrete or seasoned asphalt surface and activate the parking
brake. Block the FRONT wheels of the vehicle with appropriate wheel chocks; making sure the
vehicle’s transmission is in 1st gear (manual) or “Park” (automatic).
3. Using a properly rated floor jack, lift the REAR wheels of the vehicle off the ground. Place support
stands, rated for the vehicle’s weight, and in the factory specified locations. Refer to the vehicle
Owner’s Manual. Prior to lowering the vehicle onto the stands, make sure the supports will securely
contact the chassis.
It is very important that the vehicle is properly supported during this installation to prevent personal
injury and chassis damage! Make sure that the supports stands are properly placed prior to
performing the following procedures. We DO NOT RECOMMEND using wheel ramps while
performing this installation.
4. Slowly lower the vehicle onto the stands and, before placing the vehicle’s entire weight on them, again
check that they properly and securely contact the chassis as described above.
5. Check for possible interference with any lines, wires, cables, or other easily damaged components.

SHACKLE INSTALLATION
1. Block the front wheel and raise the back of the truck. Place jack stands under the frame just ahead of
the front spring hangers.
2. Position the rear end with a floor jack so there is no pressure on the leaf springs at the rear shackles.
Remove the spring eyebolts from the shackle and remove it from the leaf spring. CAUTION: Leaf
springs are under tension, use caution when disconnecting.
3. Lift the rear of the spring up and place the new shackle on the spring. Make sure you put the spring
eyebolt in from the inside out so the threads are toward the outside.
4. Lower the shackle into position, into the stock hanger on the frame and slide the spring eyebolt
through the spring into place. (Photo 3) Raise the truck with the floor jack just until the truck lifts off the
stands. Now tighten the four spring eyebolts on the shackles. Remove the jack stands carefully and
lower the truck to the ground. Your installation is now complete.
All hardware being fastened to the vehicle’s original fastening points should be torqued to the proper
specifications. To prevent chassis damage, never over-torque the hardware.
6. Check that all components and fasteners have been properly installed, tightened and torqued.
7. Check brake hoses, and other components for any possible interference.
8. Lift vehicle and remove support stands. Carefully lower vehicle to ground.
9. Immediately test-drive the vehicle in a remote location so that you can become accustomed to the
revised driving characteristics and handling. Be aware that the vehicle will handle substantially
different now that it has been modified.
10. Installation is complete. Check all of the hardware and re-torque at intervals for the first 10, 100, 1000
miles.
