Peterbilt Fenders can be specially ordered up to 4″ deeper than the stock Peterbilt fender. Front fenders can be ordered with SHIFT’s advanced rubber lining or a stock Peterbilt fender liner can be installed to protect from rocks and debris. Shift front fenders weight approximately 23lbs per fender including the fender liner. Front Fenders come untrimmed and require a body shop for proper fitment. Compatible only for a Peterbilt 389 Product is sold per fender. Please note: Order processing time may take up to 3 weeks to complete orders as these are custom orders. We appreciate your patience.
