SLP's new 25% Underdrive Harmonic Balancer / Underdrive Pulleys for LS1 F-Bodies 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. Other unique design strengths include 100% steel construction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads. Includes a new balancer bolt and detailed installation instructions.

NOTE: Requires 2 new belts (Gates #K060763 and #K040378 or equivalent, not included). For LS1 F-Bodies only.
