RRM SX4 Underdrive Pulley Kit

This pulley and belt combo will breath life into your SX4 by unleashing up to 5 h.p. and drastically improving throttle response. The kit comes with CNC machined aluminum pulley and new matched UD belt. This pulley is lighter, stronger and smaller than stock. A true value and the perfect place to start modding. It also features a stainless steel reinforcement hub so it wont wear out and start to leak like the stock pulley will over time. Applies to the 2007-2009 HB and 2008-2009 Sedan.
