Heavy-duty C-Notches that are unlike anything else on the market. The C-Notches are significantly longer than other design and feature reinforcements in multiple planes. They provide ample axle clearance while maintaining frame strength, both torsionally and longitudinally — even when carrying a load. C-Notches use a “bolt-in” design and include Grade 8 hardware, template and installation instructions.
