Harmonic Balancer/Underdrive Pulley, 2004-2006 GTO

SLPs new 25 percent underdrive balancer for LS1 GTOs incorporates a number of high-quality features you will not 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 percent 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 (Dayco # 760K6 and # 405K4 or equivalent, not included). For GTOs only.

100 percent steel construction

Integral timing marks and puller-mounting threads
