Description

The Michigan Motorsports LS Crankshaft / Harmonic Balancer Bolt (SKU: MMHDBLS34) is a superior OEM-style replacement for GM LS engines from 4.8L up to 6.2L (excluding dry-sump LS3/LS7/LS9). Crafted from 180 ksi tensile strength chromoly steel, this M16×2 bolt outperforms factory one-time-use bolts with reuse reliability and extreme clamping strength. It comes with a thick load-spreading washer for even pressure distribution and fits all Gen III/IV LS engines (LS1, LS3, LQ4, LM7, LC9, L96). Torque to 215 ft·lb with 30-weight oil, providing exceptional durability during rebuilds or high-performance applications.
