HKS Upgraded Timing Belt for RB20 RB25 RB26DET (T)

This upgraded timing belt from HKS is engineered to replace the factory belt on Nissan RB-series engines, providing reliable cam timing for RB20, RB25 and RB26DET applications. Designed as a performance-oriented service part, the belt helps maintain precise valve timing under high‑load and high‑RPM conditions typical of tuned RB platforms. Ideal for maintenance or power-upgrades, it supports long-term engine durability when installed as part of scheduled timing system service.
