FASS Fabrication is our in-house line of heavy-duty, custom-built parts for diesel trucks — designed, welded, and finished by the FASS Motorsports fab shop. The lineup covers traction bars, radius arms, extended and rear control arms, dual steering stabilizers, coilover conversions, bed-mounted transmission coolers, battery hold-downs, and bolt-in hood mirror kits, with fitments for Ram 2500/3500 and Ford F-250/F-350 Super Duty. Built to hold up to hard-driven towing and high-horsepower diesel use.
