Two tough black poly fenders (mounting brackets and hardware sold separately). This set does two wheels (a single axle). Two sets are required for tandem axles. Fits trucks with 16" to 17" dual rear wheels. SEE DISCLAIMER BELOW. IMPORTANT. PLEASE READ: Please check measurements to make sure these fenders will fit your truck prior to purchase. These fenders measure 37 inches end to end. They are 19" wide. When placed on the ground they measure 15 inches from the ground to the top of the fender. They fit most but may not fit all trucks with 16 to 17" tires. Pay particular attention to fender width. If you purchase the fenders and they do not fit you can return them for a refund, but we do not pay return shipping.
