2021+ Ram TRX Supercharger Parts

If you want more boost, you just need to drive the supercharger faster. This is done by changing the pulleys and belts. You can switch to a smaller drive pulley on the supercharger and/or a larger crank pulley on the motor. Stock, the TRX puts out 11 psi of boost. Here's a few notes for reference, but as always, talk to your tuner first!

• Gates K100594HD belt is often paired with 2.75/2.85" pulleys with the ATI crank pulley for 17-18 psi.
