Factory Links Rear Wheel Bearing Kit RWK-T-039 — OEM-spec bearings, double-lip NBR seals & marine-grade grease

Factory Links OEM Series Rear Wheel Bearing Kit RWK-T-039 is a complete rear-hub rebuild kit with OEM-spec deep groove bearings, double-lip NBR seals, and marine-grade grease engineered for off-road torque and contamination protection.

When your dirt bike rear hub faces chain-driven loads, heat, and mud, standard replacements can fail sooner than expected. 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.

How does this kit handle the extra torque at the rear hub?

The 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.

• High-capacity deep groove ball bearings sized to OEM tolerances
• Precision internal clearance for consistent load distribution
• Grease formulation resistant to shear and high temperatures

Will the seals keep out water, mud, and chain grime?

Yes — the kit uses double-lip NBR oil seals intended to repel moisture, sand, and lubricant contamination while retaining grease. The dual sealing lips add a secondary barrier so debris swept off the sprocket and chain has less chance of reaching rolling elements.

• Nitrile Butadiene Rubber (NBR) construction for abrasion resistance
• Double-lip profile to reduce ingress and preserve grease life
• Close-fit dimensions to maintain proper sealing under hub movement

What does the kit include and how does it simplify a hub rebuild?

Each RWK-T-039 package contains the bearings, oil seals, and any model-specific spacers required to restore correct axle alignment and wheel spacing. Providing all necessary parts in one box avoids guesswork and ensures components are matched for proper installation and long-term performance.

• Complete set of rear wheel bearings matched to applicable models
• Double-lip NBR oil seals pre-installed or supplied loose for fitment
• Model-specific spacers where applicable for correct wheel centering

Which motorcycles is this kit compatible with?

The RWK-T-039 fits a broad range of KTM, Husqvarna, and Gas Gas models spanning small-displacement youth bikes through larger enduro and motocross platforms across many production years. Check the model fitment list before ordering to confirm compatibility for a specific year and variant.

• Covers multiple KTM models from 85 SX up through 530-series bikes across many years
• Includes Husqvarna TC, FC, FE, FX, TE, TX, and FS series models where specified
• Model fitment varies by year—verify against your bike before installation

Who is this for? Riders and mechanics who need a dependable rear hub service solution for off-road motorcycles will value this kit: shop owners and home wrenches rebuilding wheels, racers seeking reduced downtime, and adventure riders who require a durable bearing and seal package that stands up to water crossings, mud, and heat. If you want an OEM-quality replacement with enhanced sealing and lubrication specifically tuned for rear-hub loads, the Factory Links RWK-T-039 delivers the parts and protection needed to get your rear wheel back to precise, reliable operation.
