The DFC 370-48006 is a parking brake hardware kit that replaces the springs, hold-down hardware, and adjuster parts for the rear drum-in-hat parking brake used on GM full-size trucks and SUVs. Sold as a complete axle set covering both sides rather than per wheel, one kit services the entire parking brake assembly. DFC builds the parts from premium spring materials to maintain consistent shoe tension, which helps prevent premature wear and reduce noise and vibration.
