Note: Requires two new belts; Dayco belts p/n 760K6 and 405K4 or equivalent (not included). For GTOs only.
- SLP's 25% underdrive pulley balancer for GTOs incorporate 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 GTO balancers.

SLP Harmonic Balancer/Underdrive Pulleys include a new balancer bolt and detailed installation instructions.
