A modification component designed for Chevrolet C10 trucks manufactured between 1973 and 1987, the “C-notch kit” allows for a lowered rear suspension. The modification involves cutting a “C” shape into the truck’s frame, providing increased clearance for the axle during suspension travel. This alteration prevents the axle from contacting the frame, particularly when the vehicle is lowered.
The lowered stance achieved through this modification offers aesthetic improvements and can enhance handling characteristics. Lowering the center of gravity improves stability and reduces body roll during cornering. Historically, lowering kits, including the C-notch, have been popular among truck enthusiasts seeking a custom appearance and performance enhancements. The C-notch addresses potential clearance issues that arise when lowering a vehicle’s suspension.
