MEUS RACING AR45 Brass Steering Knuckles for Axial SCX10 PRO & SCX10 III — Black Anodized, Direct-Fit Heavy Ballast

MEUS RACING AR45 brass steering knuckles are heavy, CNC-machined replacements for the factory plastic knuckles on Axial SCX10 PRO and SCX10 III 1/10 crawlers, improving axle weight and steering durability.

If your crawler needs tougher steering pivots and a lower center of gravity without changing suspension geometry, these AR45 knuckles offer a direct-fit brass upgrade. Machined from solid brass and finished in black anodize, they replace the stock AXI232060 plastic parts and add ballast to the axle ends. That extra mass helps stabilize the rig on technical lines, while brass construction resists wear from rocks and repeated impacts better than molded plastic.

How do these knuckles affect handling on rocky trails?

Adding 62.5 g per knuckle shifts weight outward and downward at the axle ends, which can reduce roll and improve tire contact on uneven terrain. The extra spoke weight smooths slow-speed crawling and increases traction without changing suspension links or geometry.

• Each knuckle weighs 62.5 g to add axle-end ballast.
• Lowered center of gravity helps reduce body roll.
• Smoother tire bite on obstacles and rock work.

Will these brass knuckles fit my Axial SCX10 PRO or SCX10 III without modifications?

Yes — the AR45 units are designed as direct replacements for the AXI232060 plastic knuckles used on those Axial models. They include the necessary fastener to secure one side and are CNC-machined to match factory mounting points for straightforward installation.

• Direct-fit replacement for AXI232060 plastic knuckles.
• Includes one screw for mounting; two knuckles supplied per package.
• No need to alter suspension geometry or axle shafts.

How durable are these compared with the stock plastic parts?

Brass resists cracking and deformation far better than plastic under repeated impacts and tight rock strikes. The CNC machining yields precise tolerances for snug bearings and consistent steering, while the black anodized finish improves corrosion resistance and appearance.

• Solid brass construction withstands impact and wear.
• Precision CNC machining ensures reliable fit and steering action.
• Black anodized finish enhances durability and visual appeal.

What else should I know about installation and compatibility?

Installers should inspect bearings, hardware, and axle hexes during swap to ensure smooth operation. Because these knuckles add unsprung weight, pairing them with appropriate shocks or tuning may be beneficial for optimal performance on different terrain.

• Check bearings and hardware when replacing knuckles.
• Consider shock tune for increased unsprung weight.
• Package contains two knuckles and one screw; verify you have remaining fasteners before installation.

Who is this for: Builders and hobbyists who run Axial SCX10 PRO or SCX10 III 1/10 crawlers and want a simple, durable way to add axle-end weight and strengthen steering pivots. These knuckles suit trail bashers focused on rock crawling, competitors who need repeatable steering geometry under stress, and anyone replacing damaged plastic knuckles with a longer-lasting metal alternative.
