Traxxas Differential Spool Steel

Traxxas Differential Spool is a direct replacement that locks the axle so both wheels receive equal power. That locked setup gives predictable traction for straight-line sand drags, rock climbs, and pulling applications, and it can also change handling when used only in the rear.

Key Features

• Locks the axle to deliver equal power to both wheels for consistent traction.
• Install spools in both front and rear diffs for full 4WD traction during sand drags, rock climbs, or pulling.
• Fit a spool in the rear diff to let the rear end rotate and slide through tight corners for easier cornering on narrow tracks.
• Made from steel with a corrosion-resistant finish for long service life in off-road conditions.
• Recommended for off-road use only.
• Requires 5379X or 5379R ring gears.

Why Choose This Product

If you need consistent, locked-axle traction for pulling or straight-line performance, the Traxxas Differential Spool provides a simple, durable solution. Steel construction and corrosion resistance mean the spool stands up to harsh off-road environments while changing how your truck transfers power and handles corners.
