Genuine Japanese OE-Manufacturer Components

Not all timing belt kits are created equal.

Company23 sources its timing components directly from established Japanese manufacturers that supply original equipment to Subaru. Rather than relying on generic aftermarket alternatives, Company23 carefully selects components designed to deliver the quality and reliability expected from OE parts.

Each kit combines genuine OE-manufacturer components with Company23's attention to detail.

Genuine Components. No Counterfeits.

Company23 works directly with trusted component manufacturers to maintain authenticity and consistent quality.

By sourcing directly from manufacturers, Company23 reduces the risk of counterfeit components entering its timing kits, providing additional confidence when maintaining your Subaru engine.

Component Manufacturers

Company23 believes in complete transparency about the components used in its timing kits.

• Timing Belt: Mitsuboshi, featuring Company23 branding.

• Timing Belt Tensioner: NTN.

• Idler Bearings: NSK, Koyo and NTN.

These manufacturers are established suppliers of Japanese automotive components and are recognized for their OE manufacturing expertise.

Engineered With Attention to Detail

Company23 develops its timing kits with Subaru enthusiasts in mind. From component selection to packaging, every detail is considered to deliver a reliable timing belt replacement solution.

Custom Protective Packaging

Company23 timing kits arrive in custom packaging designed specifically for their components.

Packaging dimensions and belt storage requirements have been developed with recommendations from the belt manufacturer to help protect the components during storage and shipping.

Model-Specific Components

Subaru used different timing belt and idler configurations across its SOHC engine applications.

Company23 offers application-specific timing kits to account for these differences, helping ensure the correct components are supplied for your vehicle.

OEM-Quality Black Timing Belt

Company23 deliberately uses a black Mitsuboshi timing belt rather than coloured alternatives.

Some coloured timing belts can leave unwanted residue on idlers and inside timing covers as their coloured coatings wear.

Company23's black Mitsuboshi timing belt provides proven OE-manufacturer quality without unnecessary cosmetic coatings. Each belt features additional Company23 branding.
