Belt Styles

V-groove belts or V-Belts have a slim, triangular profile, while serpentine belts are flat and have longitudinal ribs. Both are considered types of friction drive belts.

For transferring greater amounts of torque, some accessory systems use belts with teeth or cogs. There are several types, including gilmer and HTD (High Torque Drive) belts. The belts used to drive superchargers are examples of toothed belts. In addition to length and width, you’ll need to know the shape and number of the teeth on a replacement belt.

Accessory Belt Maintenance

If your V-belt, serpentine, gilmer, or HTD belt starts to make noise, or it’s showing signs of wear, it might be time to shop at Summit Racing for a replacement! You can shop by belt size, or use the Make/Model search to find the stock replacement belt for your vehicle. Read this article for more advice on inspecting and troubleshooting your accessory belts. Summit also carries serpentine belt tools to help make installation and service easier.

Top Brands

A no-name belt could leave you stranded, so Summit only carries serpentine, V-belt, gilmer, and HTD belts from trusted manufacturers like Motorcraft, Goodyear, ACDelco, Continental, OMIX-ADA, Jones Racing, and more.
