From mild to wild, let KRC complete your front engine.

  
 

 
KRC's modular pulley kits provide several options when building your serpentine belt system. Our pulley kits weigh only 1.8 lbs. including all hardware, while the average billet aluminum V-belt set weigh almost 5 lbs. With a lighter pulley system you can free up rotating weight, giving you additional horsepower gains. Between using a KRC serpentine pulley system, power steering pump and bolt-on reservoir tank, you can save around 9 lbs. on the front of the car. Kits are available for Chevrolet, Dodge and Ford.

Pulley Ratios
KRC offers our pulley kits in 15%, 30% and 1-to-1 water pump reductions. Choosing the right pulley ratio for your application is critical. Turning the water pump to fast, or too slow, will result in engine damage. Under racing conditions water pump speed must be kept between 5,000 and 6,500 RPM for proper cooling. Adjusting the speed can be done with the crankshaft pulley. A smaller crankshaft pulley will reduce the water pump speed. Check with your engine builder for their recommended pulley reduction percentages.

Pro Series Pulley Kits
Our Professional Series kits come with a 4.0" aluminum water pump pulley, with a 6-groove main drive and 3-groove accessory drive, an aluminum crankshaft pulley, R-LOK crank adapter, belt (most kits) and the appropriate hardware. Professional series kits will also clear cartridge style water pumps.


All kits are designed to fit a 4.2" serpentine pulley power steering pump. Additional accessories and/or a different power steering pump pulley size may require a different belt length. Click here to view the KRC Belt Chart.
