AIMROCK Aluminum Differential Locker Spool for Traxxas 1/10 2WD Slash, Rustler, Stampede, Bandit

This aluminum differential locker spool from AIMROCK replaces the factory differential in the transmission gearbox of your Traxxas 1/10 2WD truck. Designed to fit Slash, Rustler, Stampede, and Bandit (VXL/XL-5 variants), it locks the front differential to drive both front wheels equally. CNC machined from aluminum for durability, it suits off-road use where maximum traction is needed.

What does the locker spool do?

It eliminates the differential action, forcing both front wheels to spin at the same speed. This prevents one wheel from spinning freely when traction is lost, improving forward bite on loose surfaces. The result is more predictable power delivery during acceleration and climbing.

Construction and Fit

The spool is machined from a single piece of aluminum on CNC equipment. Aluminum is lighter than steel but still wear-resistant, making it a solid upgrade for rugged terrain. The part weighs just 0.458 ounces and measures 2.95 x 2.64 x 0.51 inches in its package. It requires no modifications to install on the listed Traxxas models.

Compatible Vehicles

• Traxxas Slash 2WD (VXL and XL-5)
• Traxxas Rustler 2WD (VXL and XL-5)
• Traxxas Stampede 2WD (VXL and XL-5)
• Traxxas Bandit 2WD (VXL and XL-5)

Note that this spool replaces the front differential. For vehicles with rear differentials, check compatibility before ordering.

Frequently Asked Questions

Will this fit a Traxxas Slash 2WD VXL?

Yes, the spool is specifically compatible with the Slash 2WD (VXL and XL-5) along with the other listed models.

Is it made of plastic or metal?

The spool is made from CNC-machined aluminum, not plastic. Aluminum offers better durability and wear resistance than stock plastic parts.

Is it recommended for on-road driving?

The manufacturer recommends off-road use only. On pavement the locked differential can cause handling issues and increased tire wear.
