Product Description:
Camaro/Firebird 98-2002 LS1 Pulley Kit, 25% Crank/ 15% Alternator, shipping is not included
ASP LS1 underdrive pulley kit reduces parasitic power losses associated with high accessory speeds, freeing up additional HP. It also reduces the rotating inertia on the front of the crankshaft allowing for faster revving. ASP has seen just over 13 rear wheel hp increase with this kit installed on stock LS1s.
