TSP utilizes a PowerBond Race Series SFI-approved 10 percent underdrive balancer pulley (PN 25-PBU1480-SS10; retail $199.99). The balancer is put over the crankshaft hub and pressed on with an LS-specific tool. Once the balancer is fully seated, a new GM crankshaft bolt is torqued to 37 ft-lb, followed by an additional 140 degrees of rotation with a torque-angle gauge. View Related Article
