Angry Ass | M60 Underdrive Pulleys
Fine tune your build with our underdrive pulley options. Underdrive the power steering to reduce steering assist and free up some power. Or add in BMW’s own Euro E34 M60 water pump pulley P/N 11511733429 to free a bit more power. Either way we have you covered.
ATTENTION: Underdriving the water pump means you are reducing the flow of coolant, which can lead to increased coolant temperatures depending on your region, engine output, and general cooling system state of health. BMW specified this larger unit on many European-delivery cars, which typically operated in cooler climates than some regions of the U.S.
Additional Information
Angry Ass power steering pulley is machined from 6061-T651 and hard-anodized to MIL-A-8625 Type III, all right here in the USA
Power steering hardware is OEM BMW
Water pump pulley is straight from the OEM parts bin in Germany and underdrives the water pump as much as certain competitors’ aluminum water pump pulleys; costs a fraction of an aluminum part; and is lighter to boot
Water pump bolts are OEM, but the washers are equivalent to OEM quality, sourced from a U.S. supplier. We didn’t think you’d want to pay $5+ each for OEM washers
Includes new serpentine belt and Loctite 243
