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.
17% Reduction
- For those seeking a bit more power, the 17% is the ideal choice! Builds boost at a lower RPM giving you even more power down low where you need it, combined with another 1.5psi of boost at redline, it gives you the extra HP to conquer even the toughest challenge!
