Position fender over tire(s). Use a 2”x4” block tor other
suitable spacer to achieve desired clearance areound
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.
Figure 1 shows general locations of mounts on various
tandem fenders (E=end mount, C=center mount). Place
bracket against fender and frame, mark the location of
the mounting holes on the frame.

Be sure to follow truck manufacturers recommended
procedures for drilling any required holes in the frame.
The mounting support
brackets and tandem
fenders are pur-
posely 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 unneces-
sary holes.
