Name:
Powerbond 25% UD Corvette/G8 Balancer Pulley
Item#:
25-PBU1117SS25
Powerbond 25% Underdrive Crankshaft Pulley, 1997+ C5 & C6 Corvette Underdrive Pulley, as well as the Pontiac G8 GT and GXP! TSP has seen dyno gains of up to 12 RWHP with the installation of this easy bolt-on! You will be able to reuse your factory air conditioner belt on the C5 Corvettes and G8's, so you will only need to purchase the new serpentine belt!
Powerbond has recently changed the amount of underdrive for the air conditioner belt on this pulley. It used to be the stock size so your stock a/c belt would work, but they have recently made the change to 10% underdrive for the a/c side. They are shipping both models, so you will need to verify which a/c belt you will need once you receive the pulley. The main serpentine belt side of the pulley remains at 25% underdrive!
