    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. Other unique underdrive pulley design strengths include 100% steel contruction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads. SLP Harmonic Balancer/Underdrive Pulleys include a new balancer bolt and detailed installation instructions.


    Features:
  • Extra-tall belt-retention walls = no more thrown belts
  • No aftermarket tensioner required
  • 100% steel construction
  • Lighter than the stock balancer
  • Integral timing marks and puller-mounting threads
  • Keyed for high-RPM or supercharged applications
  • Does not cause false knock, retard or erratic power-curve dips
  • GM balancers include a new balancer bolt
