This SLP under-drive balance will add up to 9 horsepower and 10 ftlbs of torque to the rear wheels of your 2005-2008 5.7L or 6.1L HEMI LX or LC. Additionally, this main drive pulley features taller retention walls to prevent belt slippage or loss cause by high powered motors, integral time marks, and built in puller mounting threads.
