Installation Instructions
Installation Sheet #INS-07034
Patent Pending
NOTE: These instructions for installing Spray Master fenders are in-
tended to be a general guide to help the installer. Because of the large
number of possible mounting
configurations, the installer is
responsible for the installa-
tion design and for providing
adequate clearance around
the tire carrier (i.e. tire clear-
ance, trailer clearance, etc.)
This product may not fit all
truck models or types of
suspensions. Check truck
or trailer manufacturer for
suspension travel specifications. Modifications to the brackets and/or
the fenders may be required. Any modifications are at the discretion,
responsibility and risk of the installer and may void warranty.
1. Position the fender up-
side down, making sure
to protect the top side
from getting stratched,
etc. Take two center con-
nector clamps and, with
the square holes facing
outward, slide over the
fender center cap. Align
with the holes in the fender
and secure with 2” bolts
and lock nuts. Torque
to 16 ft. lbs.

3. Insert two T-nuts into each hidden end mount clamp from
inside clamp tube hole. Hold T-nuts in place while sliding over
the mounting tube. Do not slide hidden end mount clamp over
ribs on fender.
3A. If installing a double radius fender, do step three to both
fenders.
The figures below show the general locations of mounts on half
tandem and double radius tandem fenders (E = end mount / C =
center mount).

Half
Tandem Fender
Note: The Spray Master® half tandem fender is not universal;
there is a left hand fender (roadside) and right hand fender (curb-
side). The “hidden pocket” opening is always positioned towards
the vehicle frame.
1A. For Double Radius Fender
Only (if mounting half
tandem, go to step two).
To make a Spray
Master Double
Radius Fender,
two Half Tandem
fenders sets are
required. Take both
a roadside and a curbide
tandem fender and position
them upside down, making sure
to protect the top side from get-
ting stratched, etc. Both hidden
pockets must face the same way
- if not, you have either two road-
side or two curbside fenders. Align
the holes of the center caps of each
fender together and slide the two
center connector clamps into position over the two sets of
holes on the fender center cap surface. Secure the connec-
tor clamps with 2” bolts and lock nuts.
Torque to 16 ft. lbs.
2. Slide a hidden mount tube
with the threaded insert end
first, through the hidden
pocket opening
over to the center
rib support.
Attach to the
center rib support with a 1.5”
bolt and washer but do not
engage thread locking compound
yet, just start bolt up for positioning
purposes.
2A. If installing a double radius fender, do
step two to both fenders.
