AERO4-DS Big Brake rear axle kits replace the factory disc brakes and use the OE parking brake assembly as a compliment to front big brake upgrades on late model trucks and SUV’s. High capacity braking from the Aero4 Dust Boot calipers incorporate an exclusive dust wiper seal that further protects the piston bore from dust and corrosion.
