Mr. Gasket Starter Bolt Kits for GM LS Engines

Mr. Gasket Starter Bolt Kits are purpose-built to solve one of the most common frustrations in GM LS engine work — sourcing the correct metric starter fasteners. OEM-spec metric starter bolts for LS applications are notoriously difficult to find through traditional channels, and using incorrect hardware risks improper starter alignment, mounting failure, and costly rework. Mr. Gasket eliminates the guesswork with kits engineered specifically for the GM LS platform.

Key Features:

• Engineered specifically for GM LS engine starter installations
• Zinc-plated steel construction for corrosion resistance and long-term durability
• Knurling on bolt shanks improves starter alignment during installation
• Replaces hard-to-find OEM GM metric starter bolts
• Multiple kit configurations available to cover both GM LS starter mounting styles, as well as a universal option
• Legal for use on emissions-controlled, non-emissions-controlled, and race-only vehicles

GM LS engines use two distinct starter configurations — one requiring a long and a short bolt, and another using two long bolts. Mr. Gasket offers kits tailored to each style, as well as a universal option that includes three bolts and covers all GM LS starter applications. Whether you're performing a routine starter replacement, completing an LS swap, or building a custom LS-powered project, these kits supply the correct OEM-replacement hardware to get the job done right the first time.
