Description:

Those spinning plates whirling around on the front of your engine don't just power your water pump and turn your crankshaft-they steal away the raw power your motor is generating. Take back your lost horsepower with a BBK Underdrive Pulley Set.

Your water pump and alternator eat up the energy that would otherwise turn your tires. BBK Underdrive Pulley Sets reduce the unnecessary speed of these engine accessories, stopping them from siphoning off power. This easy upgrade translates into an average boost of 8-15 horsepower!

BBK has spent the last 2 decades souping-up street machines, and they forge their experience right into your Underdrive Pulley Set. Each piece is custom designed to maximize your performance. And, BBK uses computer-driven CNC lathes to carve your Underdrive Pulley Set with precision.

Balancing strength and weight, BBK Underdrive Pulley Sets are made from either polished aluminum or black powder-coated steel. They're direct factory replacements that mount in about 30 minutes and come with a 1-year warranty.

great performance

These pulleys did exactly what they were supposed to do. They look great too. Better gas mileage and more low end torque. Excellent
