Michigan Motorsports 1-to-3 Bolt Cam Gear Conversion Kit with Timing Chain for LS Engines

Overview

The Michigan Motorsports 1-to-3 Bolt Cam Gear Conversion Kit with Timing Chain provides a complete upgrade path for LS engines that began life with a 1-bolt cam gear. By enabling a 3-bolt timing setup, it opens access to a wider range of aftermarket cam designs while preserving a compact, front-of-engine drive system. The kit is tailored for both Gen III and Gen IV LS platforms and covers many engine families in the LS lineup, including LS1, LS2, LS3, LS6, L99, LS4, LS9, LSA, and LQ4. Whether you're swapping in a new cam, rebuilding a motor, or replacing worn factory components, this solution adds flexibility and durability without requiring major chassis changes.

What’s included and how it helps

Coupled with precision engineering, the kit pairs a 3-bolt cam sprocket with a high-strength timing chain to deliver reliable drive performance and improved valvetrain stability in performance builds. Converting the existing 1-bolt setup to a 3-bolt arrangement unlocks a broader selection of cam profiles, helping you match lift, duration, and ramp speed to your goals. The construction emphasizes durability, designed to withstand higher valve spring pressures and higher RPM operation in street and track applications.

• Converts 1-Bolt LS Camshaft to 3-Bolt Timing Set: expands upgrade options and adds durability for upgraded cams.
• Includes Premium Timing Chain & 3-Bolt Cam Gear: precise fitment with improved valvetrain stability.
• Compatible with Gen III & Gen IV LS Engines: supports 4.8L, 5.3L, 5.7L, 6.0L platforms including LS1 through LQ4.
• Durable Construction for Street & Performance: built to handle higher spring pressures and elevated RPM use.
• Simplifies Camshaft Upgrades: avoids hunting for limited 1-bolt options and expands upgrade paths.

Why this kit matters for your build

For street enthusiasts, LS swaps, and race-inspired projects, having a wider cam upgrade path can simplify planning and sourcing. The kit’s compatibility with Gen III and Gen IV families reduces guesswork when selecting a cam profile, while the robust components offer confidence during regular driving and spirited sessions. Real-world builds often benefit from easier installation and a straightforward path to higher-quality valvetrain parts, all without redeveloping the engine’s timing system.

• Broad cam compatibility supports diverse upgrade goals without redesigning the engine.
• Gen III/Gen IV LS compatibility minimizes sourcing challenges across common platforms.
• Durable timing components help maintain reliability during higher-load driving and testing.

Notes on installation and use

Designed to align with standard timing system tolerances, this kit supports straightforward installation by shops or skilled DIY builders. It integrates with existing front-end components and factory timing chain routing, making it a practical choice for those who want a cleaner upgrade without a major redesign. While outcomes vary with each configuration, many LS projects report smoother transitions between cam choices and more predictable valve train behavior after upgrading to a 3-bolt setup.
