ARP GM LS1/LS6 5.7L/6.0L Balancer Bolt Kit (1997-2015 Cadillac/Chevrolet/Pontiac) 234-2503

Fits select 1997-2015 Cadillac CTS-V, Chevrolet Camaro, Corvette, SS, SSR, Trailblazer, and Pontiac Firebird, G8, and GTO (5.7L / 6.0L).

Secure your harmonic balancer with confidence using the ARP 234-2503 Balancer Bolt Kit. Designed specifically for GM LS-based engines, this high-strength fastener is a critical upgrade over the factory torque-to-yield (TTY) bolt. Unlike the OE hardware, which stretches during installation and must be discarded after a single use, the ARP bolt is reusable and provides significantly more clamping force to prevent the balancer from spinning or backing off the crankshaft.

Forged from premium 8740 chrome moly steel and heat-treated to a 200,000 psi tensile strength, this bolt features an extra-tall hex head that accepts deep sockets to prevent slipping during high-torque installation. The kit includes a 1/4-inch thick, wide-faced washer to distribute the load evenly across the balancer hub, ensuring a precision fit and long-term durability.
