| Powerbond's new 25% underdrive balancer for LS1/LS6/LS2/LS3 C5 & C6 Corvette, CTS-V, and G8 GT & GXP! 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.
