Description

By slowing the rotation speed of these accessories, the system frees up power that would otherwise be lost. The kit features black powdercoated aluminum construction and includes an SFI-approved fluid-dampened crank pulley for added reliability. Designed specifically for 1998-1999 Camaro and Firebird vehicles powered by the 5.7L LS1 V8 engine, this kit provides a straightforward bolt-on installation. It is calibrated to retain the alternator's ability to maintain a proper electrical charge even at idle, preventing common issues associated with underdrive setups. This product is not C.A.R.B. approved and cannot be installed on any emissions-controlled vehicle in California; it is not for sale or shipment to the state of California.

MIA's Description

The March Performance underdrive pulley set is a two-pulley kit designed to reduce accessory drag on 1998-1999 Camaro and Firebird models equipped with the 5.7L LS1 V8 engine. These pulleys allow accessories to turn at a slower rate to increase wheel horsepower while maintaining proper charging at idle.
