Metal Axle Upgrade Kit for 1/10 RC Crawlers, CNC Aluminum Front and Rear Straight Axles, SCX10 90046 90047

CNC Aluminum Front and Rear Axle Upgrade for 1/10 RC Crawlers

Stock plastic axles are usually the first thing to flex or break once a crawler starts taking on real technical lines. This kit replaces them with front and rear straight axle assemblies machined from CNC aluminum alloy, paired with a 45# steel drive shaft built to take sustained torque and impacts. The assemblies are cut to tight tolerances with void-free construction, so they fit the 1/10 scale Axial SCX10, 90046 and 90047 platforms directly. At 620 g (about 21.9 oz), the kit also adds weight low in the chassis, which lowers the center of gravity and puts more bite on the tires over rocks and off-camber ground. Available in black or gray, and intended for builders ages 14 and up who are comfortable pulling a crawler apart.

Key Features

• CNC machined aluminum alloy: Tight tolerances and a clean, void-free finish for accurate fitment.
• 45# steel drive shaft: A high-carbon steel shaft chosen for strength and wear resistance under crawling loads.
• Front and rear straight axles: A complete pair of assemblies rather than a single-end upgrade.
• Platform-specific fit: Designed for 1/10 scale Axial SCX10, 90046 and 90047 chassis.
• 620 g added mass: Weight down low that lowers the center of gravity and improves traction on technical terrain.
• Black or gray finish: Two colorways to match a scale build.

Frequently Asked Questions

Which crawlers does this fit?

1/10 scale Axial SCX10, 90046 and 90047 platforms. Check your model number before ordering to confirm you are on one of those chassis.

Why upgrade from stock plastic axles?

Aluminum axles resist the bending and breakage that plastic suffers under technical crawling loads, and the tighter machining keeps the drivetrain better aligned.

What is 45# steel?

It is a medium to high carbon steel valued for strength and wear resistance, which is why it is used here for the drive shaft rather than the axle housings.

Does the extra weight help or hurt?

On a crawler it generally helps. The 620 g sits low in the chassis, lowering the center of gravity and increasing traction on rocks and uneven ground.

Is installation straightforward?

It is designed as a direct-fit upgrade for the listed platforms, but you will be disassembling and reassembling the drivetrain, so basic RC tools and some building experience are needed.

Is this suitable for a complete beginner?

It is aimed at intermediate and advanced hobbyists ages 14 and up who have worked on their crawler before.
