    Product Description

    Our specially designed and engineered S85 underdrive pulley kit is a great addition to the M5/M6.  This is done by improving power through reducing parasitic drag on the engine from slowing the speed of the alternator, water pump and AC compressor components. Hp Gains are approx 10-20hp depending on condition of car, climate, and other preformance products.

    For maximum performance we also suggest pairing our full exhaust system with our specially designed performance software

    Features: 

    -CNC hard anodized S85 crank pulley.  Precise and measured belt groves and bolt holes.
    -Serpentine belt
    -Power steering & AC belt

    CAN NOT BE COMBINED WITH SUPERCHARGER SYSTEM!
