Select Your Car to Verify Fitment
Constructed of light weight 6061T6 aluminum, the ALTA SC pulley body decreases rotational inertia of the supercharger adding response to your engine.
Holes are cross drilled through the pulley and over each groove, to increase belt grip and reduce belt slippage as your belt stretches. Also incorporated into the design are oversized belt retainers, which reduces belts from jumping off.
15% Reduction
- This reduction size is the market standard and produces smooth, safe power increases of around 20WHP.
