Product details
Check the 5.25-inch mounting centers before fitting this anodized Wilwood Dynalite Internal-ST brake caliper. The component is sold individually and uses 1.38/1.38-inch bores in its 0.81-inch rotor-width configuration. Dynalite Internal-ST combines a forged body and internal fluid routing with Thermlock insulated pistons. It is a four-piston caliper for a measured lug-mount assembly; rotor centering, pad sweep and clearance must be verified before the hydraulic system is commissioned. For motorsport, street-performance and specialized braking applications, Wilwood Engineering designs and manufactures disc brake systems and their individual components. Founded by Bill Wood in 1977 and based in Camarillo, California, Wilwood supplies a range encompassing calipers, rotors, master cylinders, valves, fittings and brake lines, all selected to match the complete system.

Fitment & Compatibility
This caliper requires the measured 0.81-inch rotor-width configuration and the matching lug bracket on 5.25-inch centers. Axle placement is determined by the engineered brake package, not by a generic caliper designation. Confirm the 1/8-27 NPT hydraulic inlet, pad outline and total piston area with the rest of the brake system before assembly.
