Magnum’s 4600 Series rear disc brake kits have been designed as the perfect complement our 4100 Series front disc brake kits for vehicles weighing between 2,000 and 3,000 lbs. Not only does this kit look great but it provides superior stopping power too. Our 4600 Series rear disc brake kits use 4-piston Wilwood calipers (sold separately or included in our complete CR-Series kits). 4600 Series rear kits are available for popular Ford rear axle ends including, early big bearing, small bearing, 8.8, and late big bearing flanges (kits are supplied with parts to fit both 2.375" and 2.500" axle flange offset spacing). These kits come complete with premium 11" x .812" grey iron vented rotors in duel bolt circles (either 4.50"/4.75" or 5.00"/5.50"), caliper mounting brackets, all necessary hardware and detailed installation instructions.
