Whipple Supercharger Kit W185RF Gen 6 3.0L (20142018 GM Truck 6.2L / 20152020 GM SUV 6.2L) WK-1201-30
Gen 6 Twin-Screw Supercharger System for GM 6.2L Direct Injection
The Whipple W185RF Gen 6 3.0L Supercharger Kit is the most advanced, highest-output intercooled twin-screw system available for GM 6.2L direct-injected trucks and SUVs. Backed by over 34 years of GM twin-screw supercharging expertise, this complete bolt-on package delivers massive power with OEM-level drivability, cooling, and emissions compliance.
At the heart of the system is Whipples Gen 6 W185ax 3.0-liter (3000cc) twin-screw supercharger, featuring record-setting, championship-proven rotors that push positive-displacement performance further than any competing design. The front-feed architecture and oversized 112mm inlet maximize airflow while minimizing rotor cavitation, supporting nearly any performance throttle body.
Cooling is handled by Whipples patented dual-pass, dual-core air-to-water intercooler system. Intake air passes through two intercooler cores twice, delivering nearly double the effective cooling area of conventional designs. A massive dual-pass heat exchanger and the highest-flowing intercooler pump in the segment keep IATs in check under sustained load.
This system is 100% complete and engineered to bolt onto stock engines with no internal modifications required, yet it offers ample headroom for heavily modified builds. As always, Whipple delivers more power per pound of boost than any other positive-displacement supercharger on the market.
