Michigan Motorsports LS Cam Gear Conversion Kit — 1-Bolt to 3-Bolt with Timing Chain, Fits 4.8L–6.0L LS Engines

If you’re upgrading an LS-series engine and need the flexibility to run aftermarket 3-bolt camshafts, this Michigan Motorsports conversion kit provides a complete, drop-in solution. The package pairs a precision-machined 3-bolt cam gear with a high-strength timing chain engineered to meet tight tolerances, so you can swap cams or refresh worn components without complex machining or extensive modifications. It’s designed with Gen III and Gen IV LS platforms in mind, making it suitable for a wide spectrum of street, swap, and performance builds.

Will this kit fit my LS engine and which models are supported?

The conversion set is built to fit many common LS displacements and families used in performance and swap applications. It's compatible with 4.8L, 5.3L, 5.7L, and 6.0L engines and works with a broad list of LS variants, enabling straightforward installation on many Gen III and Gen IV blocks.

• Fits LS1, LS2, LS3, LS6, L99, LS4, LS9, LSA, LQ4 and similar platforms.
• No major block modifications required for most applications.
• Engine-specific fitment checks recommended for less-common variants or aftermarket blocks.

How does this conversion improve cam upgrade options and reliability?

Factory 1-bolt cam gears limit aftermarket choices to 1-bolt cam options or require costly custom work. By converting to a 3-bolt cam sprocket and supplying a matched timing chain, this kit lets you install a wider range of performance cams and offers a stronger clamping interface under higher valvetrain loads.

• Allows use of widely available 3-bolt performance camshafts.
• 3-bolt mounting distributes load more evenly than 1-bolt designs.
• Supplied timing chain is sized for OEM-style alignment and durability.

What’s included and what should I expect during installation?

The kit arrives with a three-bolt cam sprocket and a heavy-duty timing chain matched for correct pitch and length. Installation involves removing the factory cam gear and chain, fitting the new sprocket to the cam with the supplied chain, and verifying timing marks and tension per the engine service procedures.

• Precision-machined 3-bolt cam gear included.
• High-strength timing chain designed to OEM tolerances.
• Standard mechanical skills and basic tools required; follow torque specs and timing alignment steps.

Is this suitable for performance or high-RPM applications?

The components are designed to withstand elevated valvetrain loads encountered in many street and track builds. While it enhances robustness compared with typical 1-bolt setups, pairing with appropriate lifters, springs, and correct cam selection ensures the whole valvetrain meets your RPM and duty-cycle goals.

• Engineered for increased spring pressure and higher RPM environments.
• Compatible with typical street and race cam profiles when combined with matching valvetrain parts.
• Consult your engine builder for extreme high-RPM or endurance builds.

Who is this for: Owners and builders working on Gen III/IV LS engines who want to expand camshaft choices, replace worn timing components, or increase valvetrain robustness. This conversion is ideal for enthusiasts performing cam swaps, LS transplant projects, or performance rebuilds who prefer a practical, OEM-tolerance solution without significant block alterations.
