🚙 Top RC Crawler Upgrades on AliExpress: Axles, Wheels & Essential Mods 🚙

RC crawlers continue to gain popularity among hobbyists looking for realistic performance and customisation potential. Whether you’re fine-tuning your Axial, FMS, or custom 1/10 crawler, these AliExpress upgrades offer both durability and value — perfect for serious builders and weekend trail drivers alike.

🔩 Aluminium Axles

Upgrade your rig’s drivetrain with CNC-machined aluminium axles. Stronger than plastic stock parts, these enhance rigidity, improve torque transfer, and deliver better precision when tackling steep climbs or rocky surfaces. Available for SCX10 III, Capra 1.9, and TRX-4 platforms, these axles also add a realistic metallic finish to your build.

🛞 Beadlock Wheels & Tires

Swapping to metal beadlock wheels and soft-compound tyres is one of the easiest ways to improve grip and realism. Beadlocks prevent tyre slippage under torque, while deep-tread tyres help conquer sand, mud, and uneven terrain. Choose between 1.9” or 2.2” sets depending on your crawler’s scale and clearance.

⚙️ Steel Driveshafts & Gear Sets

Steel driveshafts and upgraded gears provide better reliability during extreme crawling. Look for hardened steel shafts with universal joints to handle high torque setups. Upgraded gear sets reduce wear and improve throttle smoothness for longer-lasting performance.

💡 Scale Accessories

Give your crawler personality with functional LED lights, roof racks, recovery boards, and metal bumpers. Many kits include plug-and-play connectors compatible with most ESCs, adding both style and visibility during night runs.

🔧 Suspension & Shocks

High-quality oil-filled shocks or adjustable coilovers can completely transform your crawler’s articulation and stability. Aluminium-body dampers perform better and look fantastic with anodised finishes in silver, red, or titanium.
