Timing Set GM LS2 3-Bolt 9 Keyway Double Roller

The Timing Set GM LS2 3-Bolt 9 Keyway Double Roller from COMP CAMS is engineered for builders and enthusiasts tackling LS engine swaps and performance builds where precision camshaft timing is non-negotiable. This component synchronizes crankshaft and camshaft rotation, establishing the critical relationship that governs valve events, intake charge density, and overall engine efficiency. Whether you're restoring a classic muscle car with an LS powerplant or building a street machine, selecting the correct timing set ensures reliable operation and maximizes the potential of your cam profile.

The double roller design eliminates slack and reduces frictional losses during chain articulation, a critical advantage over single-roller configurations in high-rpm applications. The 3-bolt mounting pattern and 9-keyway interface are OEM-spec for GM LS2 blocks, ensuring drop-in compatibility without modification. COMP CAMS' proven manufacturing standards guarantee dimensional accuracy—critical because even minor timing variance will shift the power band, affect fuel economy, and compromise engine longevity. The double roller chain runs on hardened sprockets, resisting wear during extended duty cycles common in street and competition environments.

This timing set serves builders working with LS2 6.0L engines—whether in original Corvettes, Camaros, or transplant projects into non-GM platforms. Installation is straightforward for mechanics experienced with LS architecture; proper cam indexing using the keyway ensures cam timing matches specification and prevents piston-to-valve contact risk. Pair this with quality gaskets, quality oil, and a methodical first startup procedure to confirm correct timing marks alignment. For anyone running a performance cam, upgraded valvetrain, or high-boost forced induction, this COMP CAMS timing set delivers the precision and durability your build demands.
