Fitment & Compatibility
Identify the installed brake conversion before choosing this hat for Dodge Magnum and Challenger brake conversions. The offset, center register and attachment hardware must agree with the rotor and hub in that assembly. The parking-shoe diameter, anchor arrangement and complete drum-in-hat mechanism must match. A bare hat is not a complete parking-brake assembly.
