At TIMEK, we often receive insightful feedback from our aftermarket partners. Recently, one customer tested a sample of our Timing Kit TK1386 for Subaru Forester 2.5L (2015–2020) and noticed a slight color difference between our Cam Sprocket 13024-AA360 and the OEM gear. He wondered if the surface treatment was different and that’s a great technical question.

The truth is, the OEM gear only hardens the tooth tips through localized high-frequency heat treatment, leaving the rest of the surface untreated.

At TIMEK, we apply a comprehensive heat treatment to the entire gear — from tooth to hub — resulting in:

• Uniform hardness across the entire surface;
• Greater wear resistance;
• And longer service life than OEM.

Because in our philosophy, “durability begins with detail.”

The TIMEK TK1386 Timing Kit is designed for:

Subaru Forester (SJ) FB25 2.5L (2015–2020)

Subaru Outback FB25 2.5L (2015–2020)

Subaru Legacy (BN/SJ) FB25 2.5L (2015–2020)

These vehicles are among Subaru’s most popular models across North America, Japan, Europe, Australia, New Zealand, Southeast Asia, and the Middle East. Each region has distinct aftermarket demands, and TIMEK ensures every kit meets consistent standards of precision and reliability.

We utilize precision-ground gears, high-strength alloy materials, and heat treatment verified through digital hardness testing. Every timing chain, chain tensioner and guide rail is designed for precise fitment and durability under extended use — from cold starts to long-distance drives.

Therefore, TIMEK has implemented a digital inspection system and a strict double-check process before shipment. Each Timing Kit is packed in reinforced protective packaging, and undergoes two rounds of inspection — one before final warehouse  release and another before transportation — ensuring every delivery perfectly matches the customer’s order, with no missing or damaged components when customer receiving goods. 

From production to shipment, every step reflects TIMEK’s commitment to precision and customer trust.

TIMEK — Precision. Durability. Trust.
