Product details
This DH4 service kit contains two square-section seals with listed inside diameters of 1.300 and 0.740 inch. Wilwood’s nominal DH4 piston designation is separate from these physical seal dimensions. The two different ring sizes must be matched to the correct locations in the appropriate stepped-piston caliper arrangement. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.

Fitment & Compatibility
Confirm the exact DH4 or other manufacturer-listed caliper reference before choosing the pair. Check both seal IDs and the 0.099-inch thickness against the service specification. Neither the nominal piston diameter nor a generic hydraulic parking-brake description is enough to establish the correct groove and seal combination.
