React Rear Frame C-Notch - 1988-1998 Chevy/GMC C1500

Running a big rear drop and need frame clearance to back it up? The React Rear Frame C-Notch is a precision-contoured notch built to give your 1988-1998 Chevy or GMC C1500's rear axle the travel room it needs once you've dropped low enough to run out of factory frame clearance. This is the part that keeps your axle housing from hammering into your frame rails at full compression on a serious static drop.

React builds this notch to match their own axle flip kit geometry, so if you're running a React flip kit, this notch is engineered to provide exactly the clearance your specific setup needs, not a generic guess. Quality steel construction and clean contours mean your welds go in straight and the finished product looks factory-clean once ground and coated.

Pair this notch with any of our rear axle flip kits, drop shackles, or de-arched leaf spring setups. If you're planning a serious static drop and haven't budgeted for a frame notch yet, this is the part that saves your axle housing from smashing into sheet metal every time you hit a dip in the road.

Fits: Chevrolet C1500 Silverado, 1988-1998.

Notes: Requires welding for proper installation. Recommended for static drops that reduce rear axle-to-frame clearance below stock spec.

Plan for a fabrication afternoon with this one, not a quick bolt-on job, but the payoff is a rear end that can travel through its full range without hammering your frame. Combine it with your drop kit of choice for a complete, clearance-correct rear suspension build.
