This Factory Links kit is assembled to match original equipment tolerances while adding heavy-duty sealing and lubrication designed specifically for the harsher stresses of motocross, enduro, and dual-sport riding. The kit supplies every component needed to service the rear wheel—reducing play, restoring smooth rotation under load, and keeping contaminants out of the bearing cavity.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit handle the extra torque at the rear hub?\u003c\/h3\u003e\n\u003cp\u003eThe bearings use precision-ground races and load-appropriate internal clearances to resist deformation under sustained chain tension and sprocket forces. Pre-packed marine-grade grease and a robust seal design keep lubrication stable even when the hub heats up under heavy use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-capacity deep groove ball bearings sized to OEM tolerances\u003c\/li\u003e\n  \u003cli\u003ePrecision internal clearance for consistent load distribution\u003c\/li\u003e\n  \u003cli\u003eGrease formulation resistant to shear and high temperatures\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the seals keep out water, mud, and chain grime?\u003c\/h3\u003e\n\u003cp\u003eYes — the kit uses double-lip NBR oil seals intended to repel moisture, sand, and lubricant contamination while retaining grease.
