Kit uses a shackle drop as well as a longer shackle on the rear of the leaf spring to help relieve stress on the frame. A very long shackle will over time fatigue the frame and cause a popping noise under the floor board where the frame is sectioned together. We believe a 2 part design is the best solution.
Installation: Front hangers will directly replace factory hangers, removal of bumper is recommended. Support vehicle correctly, remove springs from hangers and shackle. Remove factory hardware and front leaf spring hangers. Install new hangers reusing factory hardware. Rear shackles are used in conjunction with placing the shackle hanger currently inside the frame under the frame. Simply remove the shackles, unbolt shackle hanger from inside position, place under frame, reusing factory hardware as possible. The 2 shackle hanger brace plates will be installed with 1/2 inch spacer on bottom. Use longer 3/8-3 bolts and nyloc supplied hardware on lower spaced portion. Upper bolts are 3/8-1 with nyloc. After repositioning shackle hangers, install new longer shackles, reinstall leaf springs to factory specs, check all hardware, re torque after 500 miles.
This is a hanger only kit, there are no provisions for drive line mods, brake lines, sway bars, steering. As with all lifts these factors will need to be addressed and is left up to the installer. Please make sure you have the competency to perform the needed mods.
Note: Factory crash bar is not reused with hanger kits.
