The HKS Fine Tune Timing Belt for the Toyota 1JZ-GTE engine fits JZX90, JZX100, and JZX110 JDM chassis (HKS 24999-AT003) and is supplied as a special-order item. HKS Fine Tune belts use heat-resistant H-NBR grade tooth rubber and a strengthened construction that holds stable tension under heat expansion and high RPM, reducing cracking, stretch, and tooth skip versus an OEM belt. Designed for tuned, high-output engines and suited for use with the HKS Slide Cam-Pulley.
