EBMX Competition Jackshaft for Surron Ultra Bee

Built for high-performance racing and extreme off-road riding, the EBMX Competition Jackshaft is the ultimate upgrade for Ultra Bee riders pushing the limits. Designed in-house and tested in E-Xplorer and global race events, this jackshaft was engineered to withstand the power and punishment that the stock system simply can’t handle.

Why Upgrade?

The stock Ultra Bee jackshaft was never designed for 50+ kW power, 90-foot jumps, or aggressive off-road abuse. When upgrading to a chain drive for increased power and reliability, the original jackshaft becomes a weak point—suffering from secondary sprocket bolt failures and bearing issues. The EBMX Competition Jackshaft eliminates these failures with a race-proven, ultra-durable design.

Key Features:

• Solid Steel Construction – Replaces the stock aluminum body, keeping bearings secure and significantly increasing strength.
• Larger Diameter Design – Provides greater durability and longevity under extreme loads.
• Eight Hybrid Bearings – Upgraded from four stock roller bearings for increased support and reliability.
• Spline & Sprocket Upgrade – Eliminates the common failure of 12.9-grade bolts shearing under heavy load.
• Fully Serviceable – Designed for easy disassembly, maintenance, and part replacement.

Maintenance Notes:

For peak performance, EBMX recommends removing the jackshaft and repacking the bearings with grease every six months, depending on usage. All replacement parts and bearings are stocked by EBMX, ensuring long-term serviceability.

Who Needs This?

If you’re racing, hitting big jumps, or even doing mild track work, this jackshaft is a must-have for reliability and performance. Upgrade today and ride with confidence.
