SLP's new 25% Underdrive Balancer - Pulley for LS2 engine 2005+ C6 Corvette. The pulley incorporates a number of high-quality features you won't find on any other aftermarket unit. Among them are a pair of extra-tall belt-retention walls that eliminate the belt-slippage issues common to other balancers. Other unique design strengths include 100% steel construction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads. Kit includes a new balancer bolt and detailed installation instructions. Gains of up to 10 horsepower can be expected.
NOTE: Requires new serpentine belt (Dayco #5060780 or equivalent, not included).
