F. 

Drill four 5/16” holes through the fender using the holes in bracket PB5071 
as a guide (Figure 8).   

 

a. 

Install the 5/16” x 1 ¼” bolts through the bracket and into the fender. 

 

d. 

Use 5/16” fender washers and 5/16” nuts provided with the kit on 
the underside of the fender. 

Recommended torque is 10-15 ft-lbs. 

 
 
 

Step 4 

 

If possible, position the mounting brackets so they are 
located within 15” of the bottom of the fender. This 
protects against wind blowing the leading edge of the 
fender back into the tire (Figure 9). 
 

Tip: 

If the front fender bracket is mounted higher 

than 15”, refer

itional support. 

 
 

STEP 5 

A.  Attach the bracket (PB5010) to the fender. 

 

a. 

Drill six 5/16” holes through the fender using the 
holes in bracket PB5010 as a guide.   

 

b. 

Install the 5/16” x 1” bolts through the bracket and 
into the fender.   

 

c. 

Use six 5/16” fender washers and 5/16” nuts 
provided with the kit on the underside of the fender.   

 

d. 

Tighten the bolts.  Recommended torque is 10-
15 ft-lbs.

  

 

e.  Make sure the fenders are square and aligned 

(Figure 10).  Twists or  
bows in the fender will fatigue the 
material over time. 

 
 
STEP 6 

A.   For trucks with air suspension, raise and lower the suspension one final time to confirm 

that there is adequate clearance between the fenders and wheels.   

B.  Recheck all brackets and bolts to ensure they are tightened to the recommended torque
