HKS Fine Tune High-Performance Timing Belt | 4A-GE & 4A-GZE 16V (AE86, AW11, AE92)

HKS Fine Tune Timing Belt

For Toyota 4A-GE & 4A-GZE 16-Valve Engines | AE86, AE92, AE101 & AW11

Overview

The HKS Fine Tune Timing Belt is a performance-oriented replacement timing belt for Toyota 4A-GE and 4A-GZE 16-valve engines using the 113R19.1 belt size. It is designed for applications including the AE86 Corolla Levin and Sprinter Trueno, AE92 Levin and Trueno, AE101 4A-GZE, and 1st Gen AW11 MR2.

Developed for high-power and high-RPM engine use, the Fine Tune Timing Belt uses application-specific belt strength to help maintain stable tension as engine temperatures change. Its molded-tooth manufacturing process forms the belt teeth without the external compression used in conventional production methods, helping preserve tooth strength and reduce the potential for belt skipping under high engine load.

High-strength H-NBR tooth rubber provides additional durability for demanding street, track, naturally aspirated, and supercharged 4A applications.

• Designed to pair well with adjustable cam gears and HKS Slide Cam Pulleys

H-NBR & Molded-Tooth Construction

Conventional timing-belt manufacturing can form the teeth by applying pressure from the outside of the belt, placing additional stress on the tooth structure during production. The HKS Fine Tune Timing Belt instead uses a mold shaped around the finished tooth profile, allowing the teeth to be formed while preserving more of their structural strength.

The tooth section uses H-NBR rubber for additional strength, while the belt itself is tuned for the intended engine application to provide stable operation during thermal expansion and demanding high-RPM use.
