Harrop TVS2650 Supercharger Tuner Kit (99-KSM55K36) - 2009-2018 RAM 1500 5.7L HEMI
Transform the performance of your 2009-2018 RAM 1500 5.7L HEMI with the Harrop TVS2650 Supercharger Kit. Built around Eaton's largest 2650 rotating group, this system is designed to deliver strong low-rpm torque, immediate boost response, and efficient charge-air cooling for street, towing, and off-road use.
The front-drive, front-inlet layout creates a short, direct intake path to help improve boost response, while Harrop's dual-pass intercooler system, large front-mounted heat exchanger, and high-flow Bosch intercooler pump work together to control intake temperatures under load. The kit retains factory ancillaries including air conditioning and is designed to install without cutting or fabrication.

Low-RPM Torque & Response
The positive-displacement TVS2650 supercharger provides immediate boost response and a substantial increase in torque from low engine speeds through the rev range. This makes the system especially well suited for towing, off-road driving, and street applications where strong response and usable torque are important.
Advanced Intercooling
The Harrop cast aluminum manifold incorporates a large dual-pass intercooler core positioned directly beneath the supercharger discharge. This layout maximizes intercooler surface area and works with the included front-mounted heat exchanger and Bosch electric water pump to improve thermal efficiency and maintain consistent performance.
Integrated Bypass Valve
An integrated bypass valve reduces supercharger drag during light-load and off-boost operation. This helps improve drivability and reduces unnecessary parasitic loss during normal everyday driving.
