ES085TS 85T Harden Steel Spur for Trail Drivetrains

The ES085TS is a single-unit replacement spur engineered for Enduro Sendero trail trucks and offered as a direct aftermarket upgrade. The 85-tooth profile alters final drive relative to the factory 87T, providing a higher achievable top speed without requiring a pinion change.

Material and engineering: produced from Harden Steel #45 to improve tooth hardness, wear resistance and torsional stiffness compared with softer OEM materials. This construction reduces deformation under load and extends service life in trail conditions.

Installation and setup: the spur is installed adjacent to the motor pinion. Replace the existing spur, then set and verify proper gear mesh and backlash. Confirm free rotation across the drivetrain and retorque retaining fasteners to specified values to avoid preload or misalignment.

Included item: Spur Gear - 1pcs

What tolerances should I check after fitting ES085TS?

Inspect axial and radial play in the spur and pinion bearings, confirm parallel shaft alignment, and set backlash to the minimal clearance recommended for your chassis to avoid premature tooth fatigue.

Are there any gearbox changes needed to run ES085TS?

No gearbox changes are required if mounting and tooth profile match. Ensure bearing health and correct mesh; damaged bearings or bent shafts should be addressed before fitting hardened steel gears.

How does Harden Steel #45 behave compared with common alloys?

Harden Steel #45 provides higher hardness and fatigue resistance than many soft alloys and plastics, improving wear performance under cyclical trail loads, but it requires correct alignment to avoid accelerated wear on mating parts.
