Fall-Line Motorsports E39 M5 / E52 Z8 (S62) Underdrive Pulley Kit
SKU: FLM-S62-7UDP
MADE IN THE USA.
Finally an underdrive pulley kit for the S62! Underdrive pulleys reduce parasitic crankshaft drag from running certain accessories (in the case of the S62: the power steering pump, water pump, and alternator) while allowing others to remain at their same efficiency.
The specified accessories are underdriven to an acceptable extent as to not affect vehicle drivability at lower RPMs while less parasitic drag at higher RPMs results in slightly higher HP output at the wheels.
