Wilwood Forged Dynalite Internal Brake Caliper, Black, 1.98-Square-Inch Piston Area

This Wilwood Forged Dynalite Internal is a 4-piston brake caliper with a black finish for a nominally 0.81-inch-wide rotor. Its 5.25-inch lug mounting centers and 1.12-inch piston bores must match the brake assembly. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components, including calipers, rotors, master cylinders, valves, fittings and brake lines for motorsport, street-performance and specialized applications.

This four-piston Dynalite uses internal fluid transfer in a spacerless body. Its 5.25-inch mounting pattern is only one compatibility dimension: rotor position, body clearance and hydraulic area also need to agree.

Fitment & Compatibility

Check mounting-center spacing and bracket offset together, then confirm the pad sits fully on the rotor friction surface. Piston area must suit the master cylinder and front-to-rear brake balance.

This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
