The FAS Predator Lower Pulley is the easiest power adder available for the 6.2L supercharged platform — a true slip-on design that increases boost by 1.5–2 psi and delivers 40–70+ whp over stock with absolutely no tune required. No removal of the OEM harmonic balancer. No belt issues. No warranty headaches.
With 25+ years in serpentine belt pulley manufacturing, FAS Motorsports engineered the Predator to be the definitive no-tune pulley — lighter than the competition, properly designed for zero belt squeak or slip, and backed by a patent-pending design that keeps your factory dampening intact.
