GReddy Extreme Timing Belt for Nissan RB20DE(T)/RB25DE(T)/RB26DETT Engines
The GReddy 13524500 Extreme Timing Belt stands as the ultimate replacement for stock belts in Nissan RB-series engines, engineered with high-saturation H-NBR rubber and specialized tooth construction to prevent cracking from heat, stretching, skipping, or snapping under high-RPM abuse or extreme conditions. This belt maintains precise valve timing across the full rev range, ensuring consistent performance and engine protection in tuned or racing applications where factory belts fail prematurely.
Designed specifically for RB20DE(T), RB25DE(T), and RB26DETT engines, it fits R32/R33/R34 Skyline GT-R, GTST, and related models with direct OEM bolt-on compatibility. The innovative rib design absorbs stress and resists deformation, extending service life beyond 60,000 miles in demanding street or track use while supporting modifications up to 800+ HP without timing slip.
For RB engine owners demanding reliability in high-stress environments, the GReddy Extreme Timing Belt provides the durable, heat-resistant solution that keeps your build synchronized and safe.
