The Eastwood Under Car Fender Roller is an essential DIY tool for custom body and suspension modifications. This tool gently flattens the inner fender lip, increasing the clearance between your fenders and the tires. By doing so, you’ll be able to lower the ride height without causing tire rubs. In the process, it eliminates the sharp edge so it won’t slice through your tires. Rollers also allow auto enthusiasts to run taller, wider tires and wheels by flaring the fenders to make them more accommodating. You can even use them when fixing damage to the wheel arch.
