FAS 900 Package | RAM TRX

The FAS 900 Package for the RAM 1500 TRX represents the ideal middle ground between all-out race performance and a refined, street-drivable build. Targeting a verified 900 wheel horsepower, this package is engineered specifically for the 6.2L supercharged HEMI engine in the TRX and includes a precisely selected combination of hardware and professional calibration to achieve that goal safely and reliably. The build includes a custom pulley upgrade to raise supercharger boost pressure, high-flow injectors to support the increased fuel demand at higher power levels, and a pinned crankshaft to ensure the rotating assembly remains secure under the elevated torque and RPM. A thermostat upgrade helps manage engine operating temperatures during spirited driving, and a supporting cooling system modification further reduces heat soak risk. Once all hardware is installed, the vehicle goes through a comprehensive custom dyno tune by the F.A.S. Motorsports team, calibrating all engine parameters to maximize power delivery while maintaining safe operating margins. This package is ideal for TRX owners who want significantly more performance than the 800HP build without committing to the full 1000HP build level, and it remains daily drivable thanks to careful component selection and professional tuning. Every FAS 900 TRX Package is assembled and tuned in-house at F.A.S. Motorsports.
