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.
FEATURES:
- Extra-tall belt-retention “walls”—no more thrown belts!
- No aftermarket tensioner required
- 100% steel construction
- Lighter than the stock balancer
- Integral timing marks and puller-mounting threads
- Keyed for high-rpm or supercharged applications

NOTE:
Requires a new Crank Bolt, Serpentine Belt, and A/C Belt.

Great product
Right product just had to go to machine shop to get it honed out to the right size as it is made to fit many other aftermarket cranks.
Almost like stock just underdriven
