Product Details

This Dynamite Friction brake service kit is intended for rear brake maintenance on Dodge Ram heavy-duty trucks. The DFC GEOSPEC coated rotor line focuses on protecting non-friction surfaces from rust while maintaining a clean rotor appearance, and the heavy duty pad specification supports demanding pickup-truck braking use.
