Important Notes

Comes with self-tapping grease fittings.
Bushings do not come pre-greased. Synthetic or lithium grease is required during installation.
Requires bed rib or seam to be notched.
Applications with a bed rib directly above the shackle may require loosening the bed bolts and lifting the bed to remove and install the leaf spring mounting bolt.
MaxTrac does not recommend using wheels wider than 9" or wheels with less than 4.5" backspacing. Doing so will void all manufacturer warranties.
