Wilwood 140-5771-BD Forged Dynalite Drilled Rear Drag Brake Kit 2.91

Forged Dynalite Drag Rear Brake Kits

Forged Dynalite Drag Rear Brake Kits are easily installed kits available for all popular muscle car rear axles and aftermarket rear ends with custom axle ends. Kits in this group are purpose-built for stock class drag racers and other vehicles with fully functional four-wheel disc brakes. Depending on specific housing end style and axle offset, the bolt-on kits securely mount the four-piston Forged Dynalite caliper over 3/8” thick, axle-mounted steel rotors with an aluminum hat. Standard kits include solid face rotors, with the option for drilled rotor kits to further reduce unsprung weight in classes where every weight advantage is crucial.
