Wilwood Dynapro Lug Mount Single Rear Dynamic Kit SA Drilled Big Ford New Style 2.50in Offset

This Wilwood Dynapro Lug Mount Single Rear Dynamic Kit includes everything you need to upgrade your rear braking system. It features a Big Ford New Style caliper with a 2.50-inch offset and a Dynamic Stainless Super Alloy rotor that is drilled for improved heat dissipation. The lug-drive rotor mounting system is a notable feature, eliminating traditional rotor bolts. Instead, a single internal snap-ring holds the rotor to the hat, which simplifies assembly and allows the rotor to expand and contract freely with heat cycles. This independent movement helps prevent thermally generated stress at the attachment points, keeping the rotors flatter and running truer over time.

The hats are protected from wear by spring-loaded, replaceable stainless steel inserts within each lug-drive slot. These inserts cushion the interaction between the stainless steel rotor and the aluminum hat, especially when brake torque is applied. This design is particularly beneficial for vehicles that experience high rear brake heat, such as drag cars or heavy-weight vehicles that rely significantly on their rear brakes for stopping power. The drilled rotor design helps to vent gases and heat away from the braking surface, contributing to more consistent performance under demanding conditions.

This kit is designed for the Big Ford New Style rear end with a 2.50-inch offset. Ensure this offset matches your specific axle housing for proper installation. The lug-drive system simplifies the assembly process, making it a more straightforward installation compared to traditional rotor bolt setups.
