Powerbond 25% Underdrive Balancer Pulley
2010-2015 Camaro LS3 / L99, 99+ 4.8 / 5.3 / 6.0 Silverado / Sierra / SUV, 06-09 Trailblazer SS
Powerbond’s new 25% underdrive balancer for 2010-2015 Camaro LS3 / L99, 99+ 4.8 / 5.3 / 6.0 Silverado / Sierra / SUV, 06-09 Trailblazer SS incorporates a number of high-quality features you won’t find on any other aftermarket unit. Chief among them are a pair of extra-tall belt-retention walls that eliminate the belt-slippage issues endemic to other LS1 balancers (see photo). Other unique design strengths include 100% steel construction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads. Includes detailed installation instructions.
