HD Switch Front Wheel Bearing Rebuild Kit 2-Pack for 11x4-5 Wheels — 304 Stainless Axles & Sealed Bearings

HD Switch two-kit rebuild supplies premium sealed bearings and 100% 304 stainless steel axles to replace worn front wheel bearings on 11x4-5 wheels.

When front wheels wobble, make noise, or bind, worn bearings often get the blame—but a softer, pitted factory axle usually causes premature bearing failure. This HD Switch kit includes world-class sealed bearings, high-temperature synthetic grease, and hardened 304 stainless steel axles that resist rust and wear. The package is designed for Ariens and Gravely machines with 11x4-5 wheels (Ikon-X, Ikon-XD, ZT-XL and compatible ZTX models), providing a longer-lasting, maintenance-friendly rebuild compared with stock components.

How does replacing the axle with 304 stainless steel help my mower?

Factory axles are typically softer carbon steel that can score or rust over time, creating grooves that quickly wear new bearings. 304 stainless steel is harder, rust-resistant, and holds tighter tolerances, reducing recurring failures and extending service intervals.

• Harder material resists scoring and deformation under load.
• Stainless finish prevents corrosion that shortens bearing life.
• Improved tensile strength reduces bending and misalignment.
• Longer intervals between rebuilds and fewer downtime events.

What do the upgraded bearings and seals deliver compared to stock?

The bearings in this kit use robust steel shields and upgraded, wear-resistant grease to keep contaminants out and lubrication effective at high temperatures. That combination improves durability under heavy-duty lawn and landscaping use without changing fitment.

• Tough steel seals protect from dirt, grass, and water intrusion.
• Wear-resistant synthetic grease maintains film strength in heat.
• Precision-made bearings ensure smooth rolling and consistent wheel alignment.

Which mower models and wheel sizes does this kit fit?

This two-kit assembly fits tractors and zero-turn mowers that use 11x4-5 front wheels, including many Ariens Ikon-X/Ikon-XD and Gravely ZT-XL/ZTX series machines. Confirm your wheel dimensions and part numbers before ordering.

• Compatible with Ariens Ikon-X and Ikon-XD 42" and 52" models.
• Fits Gravely ZT-XL and ZTX models listed for 11x4-5 wheels (ZT42XL, ZT48XL, ZT54XL, and others in the ZT-XL line).
• Replaces OEM part numbers 00278500 and 05400726 where applicable.

What comes in the HD Switch two-kit rebuild and what should I inspect when installing?

The kit contains two complete front bearing assemblies with sealed bearings, 100% 304 stainless steel axles, and high-temp synthetic grease prepped for operation. During installation, inspect hubs, wheel studs, and the spindle bore for damage; replacing a damaged spindle or hub prevents early failure of the new components.

• Two sealed bearing assemblies with steel seals and upgraded grease.
• Two seamless 304 stainless steel axles, sized for 11x4-5 wheels.
• Installation best practices: clean hub bore, check spindle surface, torque to OEM specs.

Who is this for: Homeowners, landscapers, and professional technicians who maintain Ariens and Gravely mowers and want a durable, rust-resistant front wheel rebuild. Choose this kit if you want OEM-fit bearings with a stronger, corrosion-proof axle and grease engineered for higher temperatures—ideal for heavy use, wet conditions, or to avoid repeated bearing replacements caused by a worn axle.
