What is a fender roller?

A fender roller is a tool used in automotive repair and modification to reshape the wheel arch or fender to accommodate wider wheels or tires. It is commonly used in car tuning and modification scenes where increased performance or aesthetic improvements are desired.

The fender roller consists of a metal frame with a rolling mechanism and an adjustment knob. The rolling mechanism typically consists of a rubber roller or a metal roller with a rubber coating to protect the surface of the vehicle's fender.

To use a fender roller, the tool is usually bolted or clamped onto the vehicle's wheel hub. The adjustment knob is then turned to extend the roller outward, which puts pressure on the inside lip of the fender. This pressure gradually rolls or flattens the lip, creating more clearance for wider wheels or tires. The process is usually done incrementally, with multiple passes and adjustments, to achieve the desired shape and clearance.

Fender rollers are often used when installing aftermarket wheels and tires that have a wider offset or larger diameter than the original factory specifications. By rolling the fender, it helps prevent contact between the tires and the fender, reducing the risk of tire damage or rubbing during suspension travel or turns.

It is important to note that fender rolling is a skillful process and should be done carefully to avoid damage to the fender or paint. Improper use or excessive rolling can cause cracks or dents in the fender, requiring expensive repairs.

In addition to providing clearance for wider wheels and tires, fender rolling can also enhance the aesthetic appearance of the vehicle by creating a more flush and aggressive stance. Many car enthusiasts use fender rolling as a way to achieve a customized and unique look.

Overall, a fender roller is a useful tool for automotive enthusiasts and professionals who want to modify their vehicle's wheel arches to accommodate larger wheels and tires.
