Installation Instructions

through full suspension travel.
If any part of the Shockwave touches
the frame at anytime it will damage the
unit. This is not a warrantable
situation.

spacer on both sides of the eye will
center the Shockwave.
Note: There are holes on the lower
arm near the ball joint to mount the
factory bump stop. Although, it is not
needed unless you are having tire
clearance issues.

spindle and secure w/ castle nut and
cotter pin.
