Product details
Wilwood Engineering of Camarillo, California dates to Bill Wood’s founding of the company in 1977. It designs and builds disc brake systems and the calipers, rotors, master cylinders, valves, fittings and lines used in motorsport, street and specialized brake installations. BP-40 brake pads in the .49-inch Bridge-Bolt Dynalite/Dynapro configuration supply four replacement pads. Individual parts must match the complete brake system and its operating requirements.

BP-40 provides an aggressive initial response and good low-temperature friction, followed by stable modulation under sustained racing heat. Wilwood lists steel, stainless steel, iron, Super Alloy and titanium rotor materials. This is a racing-only selection, not a street pad; temperature needs and system balance remain part of compound selection.
Fitment & Compatibility
The listed Dynapro, bridge-bolt Dynalite, Forged XRD and UTV4/6 configurations use this retaining outline. It differs from the cotter-pin Dynalite profile; inspect the pad tabs before ordering.
