Moose Offroad 29-5081 Upper Shock Bearing Rebuild Kit — 2015-2024 Beta Xtrainer 250 / 300

Moose Offroad — Restore Rear Suspension Plushness, Updated Bearing Technology, and Precision Sealing

Eliminate rear-end stiction and restore the smooth, progressive feel of your suspension with the Moose Offroad 29-5081 Upper Shock Bearing Kit. Specifically engineered for the Beta Xtrainer 250 and 300 models from 2015 to 2024, this kit targets the upper mounting point of the rear shock. As one of the most high-load pivot points on your chassis, the upper shock bearing is constantly subjected to vertical impacts and environmental contaminants. When this bearing fails, it creates a "notchy" feel in the rear end and can cause play that compromises your bike's handling and traction.

Moose Offroad has updated older bearing and seal designs in this kit to incorporate the latest in bearing technology, ensuring a longer service life and better resistance to the elements than standard OEM replacements. Each kit is a complete rebuild solution, featuring a premium-grade bearing, high-performance seals, and precision-machined spacers and pins. By utilizing high-tensile steel and specialized elastomers, the 29-5081 kit provides a low-friction interface that allows your shock to react instantly to trail chatter and technical obstacles.

• Complete Upper Rebuild: Includes the high-quality shock bearing, seals, spacers, and pins required for a total refresh.
• Advanced Bearing Tech: Updated designs improve upon original specifications for better durability in extreme off-road conditions.
• Precision Sealing: Specialized seals prevent water and trail silt from entering the bearing race, extending maintenance intervals.
• Restore Performance: Eliminates pivot-point play to return your Xtrainer to its factory-plush suspension characteristics.
• Direct Fitment: Engineered specifically for the upper rear shock mounting position on 2015-2024 Beta Xtrainer models.

Moto-House MX Pro Tip:

The upper shock bearing is often overlooked during routine maintenance because it is tucked away under the seat and tank area. If you notice a "clunk" when lifting the bike onto a stand, this bearing is a likely culprit. When installing the Moose Offroad 29-5081 kit, we recommend a thorough cleaning of the shock eyelet before pressing in the new bearing. Use a high-quality waterproof grease on the needle rollers and the seal lips to create an additional barrier against moisture. Properly maintaining this pivot point ensures your Xtrainer remains the ultimate technical trail machine.

FAQ Questions

Q) Does this kit include the lower shock bearing?
A) No, this kit is specifically for the upper shock mounting point. The lower bearing/linkage bearings are typically sold in separate kits.

Do I need a press to install this?
A) While a bearing press is the preferred tool, many riders use a large C-clamp or a bench vise with appropriate-sized sockets to carefully press the old bearing out and the new one in.
