Regina Quad Z-Ring 520 Chain/Sprocket Kit (13/38) Honda TRX250X / TRX300EX

  • Specifically designed to withstand the high demands of ATV riding or racing, the 520 QUAD chain is our best chain for the considerable stresses an ATV drive line must transmit. Patented “spring effect” Z-Rings guarantee constant lubrication, providing long life of the chain. Pins manufactured from a special alloy steel hold up to repeated shocks and resist wear.
  • The ultimate ATV chain, developed to withstand the severe stresses of ATV riding, yet lightweight with maximum performance
  • QUAD chains feature the patented Z44 sealing rings, which greatly improve performance and wear life, making previous X-rings obsolete
  • 50% reduction in friction compared to traditional O-rings
  • Constant lubrication from special high-temperature grease in the critical pin/bushing area provides long life
  • High-carbon alloy pins to minimize wear and increased roller thickness to prolong durability
  • Thicker outer plates and quad-riveting for greater tensile strength
  • All parts are shot-peened for maximum fatigue resistance, and all chains are pre-loaded for superior performance and minimal adjustment
  • Suitable for ATVs up to 750cc
  • Includes clip type connecting link
  • 7,868 lb. tensile strength
  • Kit comes with pre-cut chain and front and rear sprockets

It is essential that all components of the final drive system (front sprocket, rear sprocket & chain) are replaced together to prevent accelerated wear from worn components mixed with new components.
  • Chromoly Steel Front Sprocket
  • High Carbon Steel Rear Sprocket
  • High carbon rear sprockets are heat treated for maximum durability and long life
