Maxtrac Suspension 301960C Rear Frame C-Notch Kit for 2019-2025 Silverado Sierra 1500

The Maxtrac Suspension 301960C is a precision-engineered rear frame C-notch kit designed for 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks (2WD and 4WD). This essential component provides the additional suspension travel needed when lowering your truck by 4 inches or more, preventing axle-to-frame contact and harsh bottoming out.

Key Features:

• Bolt-in design allows for more clearance on 6-inch and 7-inch rear drops
• Hand-fabricated from laser-cut materials for precise fit and superior strength
• Reinforces frame while providing 2-3 inches of additional upward axle travel
• Made in the USA with durable construction
• Includes pair of C-notch supports and all necessary installation hardware
• Recommended for use with rear flip kits and aggressive lowering applications

The C-notch (also called frame support or C-section) is cut and welded or bolted into the frame directly above the rear axle, creating a notched clearance area that allows the axle to move upward without hitting the frame. This modification maintains ride quality and prevents suspension damage when running lowered configurations. Professional installation is recommended as frame cutting is required.

Compatibility: Fits 2019-2025 Chevrolet Silverado 1500 and GMC Sierra 1500 models with 5.80-foot short box and 6.50-foot standard box. Can be modified to fit 8-foot bed models (see installation instructions). Does not fit models with Adaptive Ride Control or monoleaf springs.
