STM Balance Shaft Removal / Delete Kit for 4G63 Evo DSM

Firstly, Buy STM 4G63 balance shaft delete kit for Evo and DSM applications. The STM Balance Shaft Removal / Delete Kit for 4G63 Evo DSM is a purpose-built solution for enthusiasts and engine builders looking to remove the factory balance shaft system from a Mitsubishi 4G63 engine. Designed for Mitsubishi Evolution I–IX and 1G/2G DSM applications, this kit provides the essential components needed to complete a balance shaft elimination setup while retaining the correct oil-control provisions. The kit includes a genuine Mitsubishi OEM stubby shaft, Mitsubishi balance shaft cap, and ACL bearing set, making it a practical choice for 4G63 engine builds, rebuilds, and performance-focused projects.

Balance shaft removal is a common modification within the 4G63 community, particularly on performance-oriented engines. Removing the balance shaft assembly eliminates the balance shaft components and their associated rotating mass, while also removing the balance shaft belt from the engine configuration. However, the modification must be performed correctly because the oil galleries associated with the balance shaft system need to be properly addressed during installation. Technical installation documentation for 4G63 balance-shaft removal specifically warns that improper oil-gallery blocking can result in oil leaks or severe engine damage.

STM Balance Shaft Removal / Delete Kit for 4G63 Evo DSM

The STM Balance Shaft Removal / Delete Kit for 4G63 Evo DSM is designed around the Mitsubishi 4G63 platform and provides components intended for a proper balance shaft delete installation.

Applications for Mitsubishi Evolution and DSM 4G63 Engines

This kit is applicable across a wide range of Mitsubishi 4G63-powered vehicles. For Evolution owners, the listed fitment covers Evo 1, Evo 2, Evo 3, Evo 4, Evo 5, Evo 6, Evo 7, Evo 8, and Evo 9. It also covers applicable 1G and 2G DSM vehicles, including the Mitsubishi Eclipse GST/GSX, Eagle Talon TSi, and Plymouth Laser Turbo.

That broad application range makes the kit useful for engine builders who work with different generations of the 4G63 platform. However, buyers should always verify their exact engine configuration and installation requirements before ordering, especially when working with an engine that has previously been modified.

Why Use a 4G63 Balance Shaft Delete?

Firstly, deleting the balance shaft assembly removes the balance shaft components and associated belt system from the engine. This can be desirable for performance builds where the engine is being simplified during a rebuild.

Secondly, the kit provides the dedicated stubby shaft and supporting components rather than requiring the builder to source every component individually. STM specifies the Mitsubishi OEM stubby shaft and balance shaft cap along with an ACL bearing set.

Thirdly, a balance shaft delete can be incorporated into a broader 4G63 engine build. It is commonly considered alongside other engine modifications during a rebuild, particularly when the engine is already disassembled and the balance shaft system can be properly removed and the relevant oil passages addressed.

It is important to understand that a balance shaft delete is an engine modification rather than a simple external bolt-on accessory. Proper installation and correct oil-gallery blocking are essential. Technical documentation for the 4G63 specifically notes that the oil gallery must be blocked correctly after balance shaft removal to prevent serious engine problems.

Ideal for 4G63 Engine Builds and Rebuilds

The STM kit is well suited to enthusiasts building or rebuilding a Mitsubishi 4G63 engine. It can be used as part of a larger engine project involving upgraded pistons, connecting rods, bearings, turbocharger systems, fuel-system upgrades, or other performance components.

Because the kit is designed for Evolution I–IX and DSM applications, it can be relevant to both classic Mitsubishi Evolution builds and DSM projects. It is particularly useful when the engine is already apart and the builder wants to address the balance shaft system before completing the bottom-end assembly.

For professional engine builders, the kit also provides a straightforward way to identify the primary components required for the conversion. Always follow the appropriate installation procedures and verify bearing positioning, oil passages, clearances, and component condition during assembly.

Buy STM 4G63 Balance Shaft Delete Parts Online

If you are looking for a 4G63 balance shaft delete kit for sale, the STM solution provides a dedicated option for Mitsubishi Evolution and DSM engine projects.
