The RaceQuip U-Style Dragster SFI 16.1 Rated Camlock Harness set provides the best value in a purpose-built rail dragster seat belt set. Sometimes called a 4-point configuration, the shoulder harness is one continuous 3" belt that wraps around the belt bar behind the driver's head in a rail type dragster chassis. The lightweight aluminum alloy cam buckle provides precise spring pressure for a positive feel when rotating the lever to the 45 degree (right or left) unlatch movement. The cam buckle stays connected to the crotch strap to keep it out of the way when not in use. This motorsports seat belt system also features a "pull up" lap belt design which means you pull the lap belt ends toward the cam buckle to tighten the belts. This auto racing harness is manufactured with premium 3" polyester webbing and double-adjustable ends to help ease installation. Mounting of the lap belt and crotch strap is either wrap around or bolt-in with the included drop-forged steel hardware ends. Shoulders adjust from 20" to 40" and lap belt adjusts from 20" to 60".
