This is a set of (4) Tube Fenders. River Raider tube fenders are world-renowned as the best fenders for your JK Wrangler! These monsters are not simply stitched together on the inside like many cheap tube fenders, which allow rust to develop quickly. No, our River Raider fenders are fully welded the entire length of the outer tube and are made from 1.5" DOM steel tubing and heavy gauge steel with reinforcing gussets, making them the strongest tube fenders available for the JK Wrangler. These also do not bolt to the flimsy outer Jeep skin like other fenders, instead they use spacers where needed to tie into the sub-frame for superior strength. These are available in narrow and factor widths, and 2" or 4" wider than stock fenders! Our 2" Extra Wide Fenders should provide full coverage for a 4.5" backspace wheel fitted in a 12.5" wide tire. If you are running 15.5" tires on a 4.5" backspace then you will need the 4" Extra Wide Fenders for full coverage.
