I have this in sealed box as I went with supercharger and will not need this now but a very wise insatall for others. I will sell this $185 shipped to your door. SLP's new 25% underdrive balancer for 2010 L99/LS3 Camaro, 1999-2009 4.8/5.3/6.0 Silverado/Sierra/SUV and the 2006-09 Trailblazer SS incorporates a number of high quality features you won't find on any other aftermarket unit and makes up to 4.9 additional rear wheel horsepower and 6.1 ft-lbs of rear wheel torque. Among these features are a pair of extra tall belt retention walls that eliminate the belt slippage issues common with other balancers. Other unique design strengths include a 100% steel construction (other brands use aluminum), integral timing marks and built in puller mounting threads. Includes a new balancer bolt and detailed installation instructions.

NOTE: Balancer requires two new belts ARE included.
