Wilwood 140-5771-BD Forged Dynalite Rear Drag Brake Kit Drilled 2.91
Forged Dynalite Rear Drag Brake Kit
FDL Rear Drag kits are true bolt-on kits available for all popular muscle car rear axles and aftermarket rears built with custom axle ends. Kits in this group are purpose built for sportsman category door cars and others with full functional four-wheel disc brakes. Based on the specific style of housing end and axle offset, mounting kits securely install the four-piston forged Dynalite caliper over 3/8” plate steel rotors that are mounted to the axle with an aluminum hat. Standard kits include solid face rotors, with optional drilled rotor kits available to further reduce driveline weight in classes where every weight advantage is necessary.
