Product details
This six-piece square-ring pack uses the listed 1.620/1.250/1.250-inch inside-diameter sequence for the assigned Prolite 6 and Integra 6 service configurations. The mixed sizes distinguish it from other six-piston seal packs. Each hydraulic ring uses the manufacturer’s 0.099-inch section entry. Bill Wood founded Wilwood Engineering in 1977; the company is based in Camarillo, California. Wilwood designs and manufactures disc brake systems and components, from calipers and brake rotors to master cylinders, valves, fittings and brake lines, for motorsport, street-performance and specialized applications; selection depends on the complete brake system.

Fitment & Compatibility
Check the exact caliper and replacement-kit listing, including the intended larger and smaller locations. A six-piston count by itself does not identify the seal combination. Compare groove profiles and inspect piston, bore and other service components before deciding what else the repair needs.
