Single/Double Radius Fender
& Bracket Installation Instructions
Step 1
Determine proper fender position for your application.
Position fender over tire(s). Use a 2"x 4" block or other
suitable spacer to achieve desired clearance around tires. For
optimum performance, the fender should be 3" to 6" from tire.
(S.A.E. recommendation is 3" minimum) NOTE: If you have
an air suspension, make sure there is tire clearance when the
suspension is deflated.
The figure below shows general locations of mounts on various
fenders (E=end mount, C=center mount). Place bracket against
fender and frame, mark the location of the mounting
holes onE

the frame.
The mounting support
brackets and fenders are
purposely not pre-drilled
because of the many vehicle
variations and side frame
clearance problems. Drilling
to suit offers added flexibility
for mounting without
defacing the fender with
unnecessary holes.
