8. Remove the crossmember and drop
the 3/8” U-bolt through the holes.
Reinstall crossmember and tighten with
3/8” nylocs and flat washers.
Shown below:
9. Bolt the lower axle bracket to leaf
spring plate on the bottom of the axle
using the new 7/16” nylocs supplied. Do
not tighten until the lower bar is in place.
10. Install the lower arm (the longer one)
into the oem leaf spring hanger using the
factory hardware. This is a polyurethane
bushing and is lubricated at the factory
with lithium grease. Any future
lubrication can be done with any non-
petroleum based lubricant.
11. The other end of the lower bar will
attach to the axle bracket using 5/8” x 2
3/4" bolts and nylocs. This is a rubber
bushing and does not require lubrication.
Do not tighten the bar bolts yet.
12. The lower Shockwave mount is
bolted to the lower two holes of the axle
bracket with two 5/8” x 1 1/2" bolts and
nylocs The U shaped portion of the
bracket will face toward the inside of the
vehicle.
13. Bolt the axle tabs to the upper bar
as shown in the picture. Then bolt the
other end to the upper bar mount.
Do
not weld the tabs yet.
14. Before welding the tabs you must
center the axle and set the pinion angle.
This must be done at ride height. Raise
the axle until the is 14 1/2" from center
eye to center eye on the Shockwave
mounts, this is ride height. One trick that
we use to maintain the settings are to
tack weld a 4” spacer between the axle
and the frame.
