2007-2018 Chevrolet Silverado / GMC Sierra 1500 Extended/Crew Cab Welded Underbed C-Notch
This Trekline Motorsports welded underbed C-notch is engineered to create additional rear axle-to-frame clearance on lowered trucks while keeping the notch structure tucked under the bed. It is intended for serious rear drops and axle-flip combinations where factory frame clearance becomes limited.

- Weld-On Frame C-Notch Kit
Vehicle Fitment:
- 2007-2018 Chevrolet Silverado 1500 Extended / Crew Cab
- 2007-2018 GMC Sierra 1500 Extended / Crew Cab
Important Fitment & Installation Notes:
- EXTENDED CAB / CREW CAB APPLICATION. Do not substitute the Standard Cab underbed notch.
- Weld-on installation requires cutting the frame and welding; professional fabrication is recommended.
- Confirm cab configuration and body style before ordering, especially during GM body-style transition years.
- After installation, verify axle clearance, bump-stop contact, brake-line slack, driveline clearance and all fastener torque before road use.
