Can I just use my stock belt?
You could get by with your stock belt with our 3.4" pulleys. You won't however, be doing yourself our your car any favors.

We highly recommend the Goodyear Gatorback® belt for the added traction and performance you desire! The pattern on these belts help minimize slippage and MAXIMIZE your supercharger's boost levels. These belts have a strong, stretch-resistant tension member, and rubber helical cogged ribs offer maximum cord support and wear resistance.

Get the facts about Gatorback belts straight from the Goodyear!
We sell Gatorback belts at the lowest possible price, passing the savings along to our customers.
All these belts ... same low price!
