Wilwood Forged Dynalite P/S Rear Kit Chevy 12 Bolt-Spec 3.15in Bearing

If you're upgrading the rear axle on your classic muscle car, especially one with a Chevy 12-bolt rear end, this Wilwood Pro-Series rear disc brake kit is designed to give you a significant boost in stopping power. This kit replaces your stock drum brakes with a modern, high-performance disc setup, offering better heat dissipation and more consistent braking, particularly important for heavier vehicles or those used in competition. It's a complete solution for the rear axle, assuming you don't need an integrated parking brake assembly on the wheels themselves.

At the heart of this kit are the forged billet Dynalite four-piston calipers, known for their strength and compact size, allowing them to fit within many popular 15-inch wheels. They work with a two-piece hat and rotor assembly, which helps manage heat and reduces unsprung weight. You get a choice of rotor styles, allowing you to prioritize show-car looks or heavy-duty durability for demanding, high-heat situations. The calipers come in a black powder coat finish for a clean, aggressive look that also offers corrosion resistance. This kit is engineered to balance braking performance front-to-rear, ensuring your new rear brakes work effectively with your existing front setup.

This kit is specifically configured for Chevy 12-bolt rear axles that use a 3.15-inch bearing with a 2.91-inch offset. It's important to verify these dimensions on your specific axle to ensure a direct fit. While this kit doesn't include an internal parking brake mechanism, it provides a robust disc brake system that will noticeably improve your vehicle's stopping capability. For installation, you'll want to consult Wilwood's specific instructions to ensure all components are properly mounted and bled.
