Harrop TVS2650 Supercharger Tuner Kit (99-KSM66K53) - 2019-2026 RAM 1500 5.7L HEMI
Unlock serious performance from your 2019-2026 RAM 1500 5.7L HEMI with the Harrop TVS2650 Supercharger Kit. Engineered around Eaton's large and highly efficient TVS2650 rotating group, this complete supercharger system delivers immediate boost response, substantial low-rpm torque, and advanced charge-air cooling for powerful, consistent performance.
Harrop's Front Drive Front Inlet (FDFI) configuration provides a short, less restrictive intake path for excellent throttle and boost response. Combined with an advanced dual-pass intercooler, large front-mounted heat exchanger, and high-flow Bosch intercooler pump, the system is designed to manage intake temperatures during demanding street, towing, and off-road use.

TVS2650 Supercharger Technology
At the heart of the system is Eaton's TVS2650 rotating group featuring a 170-degree lobe helix angle. The positive-displacement design produces immediate boost from low engine speeds and maintains strong airflow throughout the rpm range, delivering the broad torque curve that makes a supercharged 5.7L HEMI exceptionally responsive on the street.
Advanced Intercooler System
Harrop's cast aluminum intake manifold positions a large dual-pass intercooler core directly beneath the supercharger discharge port to maximize available cooling surface area. A large front-mounted heat exchanger and high-volume Bosch electric water pump circulate coolant through the system to support consistent charge-air temperatures under demanding conditions.
Built for Towing & Off-Road Performance
The instantaneous response of the positive-displacement TVS2650 provides substantial torque from low rpm, making the system especially effective for trucks used for towing, hauling, off-road driving, and performance street use. Power remains responsive throughout the rev range without sacrificing the everyday usability expected from a RAM 1500.
Integrated Bypass Valve
An integrated bypass valve reduces drag from the supercharger rotating group during light-load and off-boost operation. This reduces unnecessary parasitic loss during normal cruising and helps maintain excellent everyday drivability.
