Installation
1. REMOVE REAR TRACKBAR AND
COIL SPRINGS
Raise and support vehicle chassis with jack
stands positioned in front of the rear lower
suspension arm brackets.
Raise and support rear axle housing with a
hydraulic jack to relieve tension from track bar
mounting hardware.
Remove rear track bar mounting hardware from
axle and chassis brackets. Retain original
hardware and remove track bar from vehicle.
Remove rear stabilizer bar drop link mounting
hardware from axle housing. Disconnect drop
links from axle and retain original hardware.
Remove lower mounting hardware from shock
absorbers and disconnect shocks from axle
brackets. Retain original hardware.
Lower rear axle housing until the coil springs
are free from upper spring mounts. Remove coil
springs from vehicle.
2. REMOVE FACTORY SPRING
MOUNTS FROM AXLE
Inspect factory spring mount on axle housing.
Locate the areas that are welded to axle tube.
Cut factory spring mount off of the axle housing.
Use care to avoid cutting into the axle tube.
HINT: A die grinder with cut-off wheel is useful
for cutting off the factory spring mount.
Remove any remaining spring mount material
from the axle housing until surface of axle tube
is smooth. HINT: A grinding wheel is useful for
removing remaining spring mount material.
Locate the long factory weld on front (driver
side) of rear axle tube.
On outboard side (closest to tire) of weld, grind
off 2” of material until smooth and flush with
surrounding area.
With the factory spring mounts removed and the
long factory weld shortened, paint bare metal
on axle tube to prevent corrosion.
