ARP Harmonic Balancer Bolt Kit – ARP-234-2503

Keep your harmonic balancer locked in place under extreme load. As the crankshaft flexes at high RPM, the balancer absorbs massive amounts of torsional energy — and the last thing you want is it walking off the snout. ARP's balancer bolt kit is engineered to hold tight where factory hardware can't.

Features

• Chromoly steel construction for superior tensile strength
• Black oxide finish for corrosion resistance
• 12-point head accepts a deep socket — no stripped heads, no excuses
• Washer included
