2010+ Camaro SS LS3 V8 Powerbond 25% Underdrive Pulley


Model Number: PBU1190-SS25

Powerbond’s new 25% underdrive balancer for LS3 2010+ Camaro’s! 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.


  • 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
