Magnuson Superchargers High Speed Cartridge for the LS Magnum 2650 (PI)

Built for LS owners who routinely spin their Magnum PI 2650 beyond OEM limits, this upgrade input‑shaft cartridge assembly is a must-have for smoother, more stable operation at extreme supercharger speeds.

Why upgrade?

• Track‑oriented headroom – ideal for overdrive crank pulleys, smaller blower pulleys, and sustained high‑RPM use in drifting, drag, road‑race, or half‑mile events.
• Plug‑and‑play install – pre‑assembled, pre‑lubed, and designed to swap in on the bench or in vehicle.
• Reduced vibration & wear – engineered to keep loads in check when the blower is pushed hardest.

*Lead times are currently 4 weeks.
