The REGINA 520 QUAD Drive Chain is an ultimate heavy-duty chain engineered specifically for ATV/quad use, where driveline shock loads, mud, and constant acceleration put extreme stress on the final drive. Thanks to REGINA’s patented Z44 sealing rings, it delivers smoother running with significantly reduced friction while keeping lubrication where it matters most—helping the chain last longer and require fewer adjustments over time.
Built with high-carbon alloy pins, increased roller thickness, thicker outer plates and quad-riveting, this chain is designed to resist wear and fatigue in harsh off-road conditions. Each chain is shot-peened for maximum fatigue resistance and pre-loaded for superior performance from the first ride.
Key features:
✅ Patented Z44 sealing rings for improved performance and extended wear life
✅ Up to 50% friction reduction compared to traditional O-ring chains
✅ Constant lubrication using special high-temperature grease in the pin/bushing area
Benefits of use:
🔹 Longer service life in demanding ATV/quad riding conditions
🔹 Smoother power transfer with less friction and heat build-up
🔹 Strong, durable construction that helps reduce stretching and adjustment needs
