6 Rib vs 8 Rib Serpentine Belt: What's the Difference?

What is the benefit of an 8-rib over a 6-rib?

8 rib belts provide 33% more surface area which results in more grip when your system is running at full strength. 6 Rib systems are a significant upgrade to a standard V-Belt System, but can still slip with high horsepower applications.

Why not use a 10 or 12-rib then?

We have found 8 rib to be the "sweet spot" when it comes to reducing belt slippage without going overboard. 99% of applications will be able to fit the additional 2 grooves of our 8 rib serpentine system in their engine bay.

When is a 10-rib necessary?

A 10 rib belt isn't required until you start talking about supercharged applications that increase your base HP and Torque by 35-40%. CVF's Supercharged Wraptor uses a 10 rib and 8 rib belt combo to get the most out of your supercharger.

Are 8-rib belts readily available?

Absolutely. CVF stocks all sizes of Gates Belts required to get your kit ready to run.

Your local auto parts store will stock a large variety of 8 rib belts from various manufacturers. If they do not have a belt in stock, they can typically order it for you and have it to you within 24 hours.

Why do other companies make 6-rib systems?

6 rib serpentine systems are cheaper to make as less aluminum is needed. 20 years ago all you were able to find was 6 rib belts when it came to serpentine, but as time goes on, so does the demand for increased horsepower.
