Gates Polychain Rear Drive Belt For Harley Dyna 2000-2006
Gates Poly Chain: The Carbon Fiber Standard for Twin Cam Dynas
The Gates Poly Chain® Rear Drive Belt for 2000–2006 Harley-Davidson Dyna models is the most advanced final drive solution available for the early Twin Cam era. As Harley-Davidson moved away from the wider 1.5″ belts to the 1-1/8″ profile, the need for stronger materials became paramount. Gates met this challenge by integrating Carbon Fiber reinforcement, creating a belt that is narrower yet significantly stronger than the original equipment.
Patented Carbon Tensile Cord Technology
The heart of the Gates Poly Chain is its carbon fiber cords. This material science breakthrough provides critical advantages for high-performance V-Twins:
- Zero Stretch: Carbon fiber is dimensionally stable. Once initial tension is set, the belt will not stretch, keeping your rear wheel perfectly aligned and eliminating the need for frequent adjustments.
- Unmatched Strength: Provides nearly double the horsepower capacity of standard aramid belts, making it the essential choice for 88″, 95″, or 103″ big-bore builds.
- Maintenance-Free: Resistant to the “set” or “shrinkage” that can occur with traditional rubber belts during seasonal storage.
High-Modulus Polyurethane Construction
Unlike standard neoprene belts, the Poly Chain is constructed from a unique high-modulus polyurethane compound. This material is virtually immune to tooth shear and offers:
- Chemical Resistance: Superior resistance to oil, grease, and road chemicals that can degrade standard rubber.
- Precision Engagement: The 14mm pitch teeth are jacketed in a low-friction fabric that reduces heat and “belt whine.”
- Debris Ejection: The tooth geometry is specifically designed to help eject road grit, preventing punctures.
