- Rear lift kit for leaf spring suspensions
Choosing a rear lift height
Rear lift height affects tire clearance, ride feel, and how the rear suspension travels over bumps. A small lift changes the geometry less than a large one, but any height change alters shock length and brake hose reach. Measure your current ride height and tire clearance before you decide how much lift suits the way you use the vehicle.
Riser blocks raise the rear axle without changing the springs themselves, so the ride can feel firmer or the rear may track differently on uneven ground. Keep the mounting hardware tight, since the U-bolts hold the blocks against the leaf packs. Re-check the installation after the first drives and whenever tires or loads change.
- Measure ride height before and after
- Check tire-to-fender clearance
- Review shock length for the new height
- Confirm the lift height before ordering
