Description & Feature
This C-Notch kit is specifically engineered for 1999–2006 Chevy Silverado 1500 and GMC Sierra 1500 trucks, as well as the 2007 Silverado and Sierra 1500 Classic models. When lowering these trucks using aftermarket suspension kits, the reduced clearance between the rear axle and frame can severely limit suspension travel, resulting in a harsh ride and increased wear on suspension components. Our precision-fabricated C-Notches are designed to solve this issue by providing the necessary frame clearance to restore full axle movement.

Each C-Notch is carefully crafted to match the factory frame rail contours of your Silverado or Sierra for a snug, secure fit. This ensures proper alignment and strength without the need for any welding — though welding can be done optionally for those who prefer a fully permanent installation. The bolt-on design makes it ideal for DIY installations or professional builds, reducing installation time and effort.

Manufactured from heavy-duty steel for strength and durability, this kit includes both left and right C-notch sections and comes complete with all necessary hardware. Whether you're building a street cruiser, show truck, or performance-oriented lowered pickup, this C-notch kit is a critical upgrade to ensure proper rear suspension travel, improved ride quality, and long-term reliability.
