NOTE: These instructions for installing Master Multi-Mount are intended to be a general
guide to help the installer. Because of the large number of possible mounting configurations,
the installer is responsible for the installation design and for providing adequate clearance
around the tire carrier (i.e. tire clearance, 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.
1) Place a Nord-Lock washer first, then the Master Multi-Mount
casting washer (the side with the bevels facing away from the
bolt head) onto a 5/8” x 6 1/2” bolt.
2) Insert the bolt and assembled washers through the slot in the
Master Multi-Mount, matching the side with the bevels to the
bevels on the washer.
3) Slide the Master Multi-Mount Frame Spacer over the bolt, making sure that the serrations of the two parts engage.
NOTE: If additional distance from the frame is needed, it can be
gained by using the 3.5” extension set (part #031-01299)
4) Insert the bolt through the selected hole in the frame, then
install a second Nord-Lock washer and a nut onto the bolt, but
only finger tight.
5) Put a 3/8” lock washer on a 3/8” x 1-1/4” bolt and thread it into
the clamp portion of the Master Mount.
6) Slide the Master Multi-Mount Tube through the clamp. Make
sure that at least 1/8” of the tube protrudes out the other side.
7) Make the desired adjustment for offset and rotational position
of the Master Multi-Mount. Then tighten the bolts to the proper
torque, 180 ft. lbs. for the 5/8” bolt and 236 in. lbs. or 19 ft. lbs.
for the 3/8” bolt.
8) Install an end cap into each end of the Master Multi-Mount tube
per directions supplied.
9) Now you can install the Spray Master fender onto the Master
Multi-Mount.
