B4850BTPACF 

Fender Mounting Instructions for MIN4050, MIN950 & MIN1550 Fenders 

 

STEP 1 

 

A.  Unpack all cartons and lay out parts. 

 

B.  Compare the parts with hardware kit B4850BTPA as shown in Figure 1. 

 

     

 

 

 

 
STEP 2 

 

A.  Measure the suspension travel.  This measurement is used to determine the distance 

between the fender and the wheel.  
 

a.  For air suspension systems, let the air out of the air bags.  

 

b.  For spring systems, measure from the stops on the springs to the bottom of the 

frame.   

 
NOTE:

 

For air suspensions with travel exceeding 6”:

   

In some cases a travel stop may need to be installed to prevent such large gaps 

between the fenders & tires.  This will help with alignment and 5

th

 wheel plate clearance.
