Bolt On OBS C-Notch Kit (1988-1998)

Gain the clearance you need without sacrificing strength with the NBI Bolt-On Frame Notch Kit for 1988-1998 Chevrolet and GMC OBS 1500 trucks. Designed specifically for single cab, extended cab, and regular cab short bed applications, this kit allows increased rear suspension travel for lowered trucks while maintaining the structural integrity of your factory frame.

Unlike weld-in kits that require extensive fabrication, the NBI notch kit utilizes a precision-engineered bolt-on design for a straightforward installation with basic shop tools. Each notch is CNC laser-cut from heavy-duty steel and engineered to fit the contours of the factory frame rails for a clean, professional appearance.

Whether you're building a street truck, autocross project, drag truck, or simply want to achieve a lower ride height without axle-to-frame interference, the NBI Bolt-On Frame Notch Kit delivers the clearance needed to keep your suspension working properly.
