Big Brake Dynamic Lug Drive - Flared Bell - Product Description

Big Brake Dynamic Lug Mount Flared Bell hats are precision machined from premium aluminum alloys for high strength and attention to minimized weight. Hats in this category feature dynamic lug mount rotor slots and a corresponding snap ring groove for use with lug mount rotors.

Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the aluminum hat from wear that would otherwise be caused by loading of the stainless steel rotor against the hat when brake torque is applied. A large, single snap-ring retains the rotor in the hat, making assembly and installation literally a snap. There is no longer any need to torque or safety wire rotor mounting bolts. The already lightweight stainless alloy discs are additionally drilled to remove all unnecessary rotating weight from the driveline.
