8-94161-860-0 Isuzu 4JA1 TFR54, D-MAX

Product Details:

1. High-Strength Material and Manufacturing Process: Made of 20CrMnTi alloy steel, treated with carburizing and quenching, the tooth surface hardness reaches 58~61HRC. The gear shell body has high strength and can withstand the impact load during synchronizer engagement, preventing deformation or fracture of the gear shell.

2. Precision Synchronizer Design: The internal teeth of the gear shell precisely mesh with the synchronizer cone ring, with a tooth side clearance tolerance of ≤0.03mm, ensuring smooth synchronizer engagement, reducing shifting shock and noise, and improving shifting feel.

3. Synchronizer Core Component: As the "toothed outer shell" of the gearbox synchronizer, it works with the synchronizer cone ring and slider to synchronize the gear speed during shifting, and is one of the key components for smooth shifting in manual transmissions.

4. Gearbox Repair and Replacement: Used for replacing faulty synchronizers in Isuzu 4JA1 model gearboxes (such as gear shell tooth surface wear and internal tooth deformation), restoring the smooth shifting function of the gearbox and avoiding problems such as shifting jams and gear grinding.

5. Commercial Vehicle Gearbox Parts: Suitable for Isuzu TFR54, D-MAX and other commercial vehicles/pickup trucks, meeting the needs of frequent shifting in freight and engineering operations. It is one of the core wear parts of the gearbox for these models.
