Compatibility

15% or 17% Supercharger Pulley

The ALTA Supercharger Pulley delivers up to 20 wheel horsepower with no additional engine or ECU modifications required. It features a stainless steel shaft coupler with an installation aperture and direct torque design for a secure fit. The lightweight aluminum body reduces rotational inertia, while oversized retainers and grooved teeth improve belt grip, finished with a sleek decorative end cap.

Tensioner Stop for R53 Supercharged Engine

Tensioner Stop

Why do you need an ALTA Tensioner Stop? Because when the serpentine belt fails, the OEM tensioner can overextend into the crank pulley, causing major damage. The ALTA Tensioner Stop limits tensioner travel to prevent this failure, saving you hundreds in repairs with one simple, affordable upgrade.
