Dynalite 4-Piston Forged Caliper Kit

The Wilwood Forged Dynalite Rear Drag Brake Kit offers a true bolt-on solution for enhanced braking performance on popular muscle car rear axles and custom aftermarket setups. Engineered specifically for drag racing, this kit provides robust four-wheel disc brake capability. At its core, the kit utilizes Wilwood's forged Dynalite calipers, which are known for their strength and reliability. These calipers house four pistons and feature a Type III Anodize finish for durability. They work in conjunction with 11.44-inch diameter solid steel rotors, finished with a black oxide coating. These rotors are mounted to the axle via machined aluminum hats, specifically designed as Drag Hats. The kit includes standard solid face rotors, but optional drilled rotors are available for classes where reducing driveline weight is critical. Key specifications include a caliper piston bore of 1.75 inches for both pistons, a combined piston area of 4.80 square inches, and stainless steel piston material. The brake pads included are Wilwood's BP-10 compound, offering a balance of stopping power and pad life suitable for drag racing applications. The hat features a standard drag style with a black E-coat finish and includes multiple bolt circle options (5 x 4.50, 5 x 4.75, and 5 x 5.00) with a 0.520 stud diameter. This kit is specifically designed for applications using a Big Ford New Style rear end axle with a 2.50-inch offset. It is compatible with 15-inch wheels, but users should consult the provided wheel clearance diagram to ensure fitment with their specific wheel design. The system utilizes a lug mount style for caliper attachment. For more detailed fitment information or custom inquiries, Wilwood recommends contacting their sales or technical support team directly.
