Key Features
- Traxxas Pro Built Assembly — This rear axle arrives fully assembled by professional technicians at the Traxxas factory, meaning it has been built to factory tolerances and quality standards, eliminating any risk of incorrect assembly and ensuring it will work perfectly right out of the box.
- Metal Half Shafts — The axle incorporates metal half shafts, which provide superior strength and durability compared to plastic alternatives, making them ideal for high-stress trail driving and preventing breakage during aggressive off-road manoeuvres.
- Complete Assembly Package — Unlike partial axle kits, this assembly includes everything you need: metal half shafts, bushings for smooth rotation, wheel hubs for secure wheel mounting, and wheel nuts for secure fastening, so you have a fully functional rear axle with nothing else to purchase.
- M2.5x0.45 NL Thread Specification — The M2.5x0.45 metric threads ensure compatibility with all TRX-4M models and guarantee precise fitment with OEM Traxxas components, eliminating any guesswork during installation.
- Two Axles Included — This package contains two complete assembled rear axles, giving you a spare or allowing you to have a backup system ready, which is invaluable for competitive racers or frequent trail runners who need peace of mind.
- Wide Compatibility — This rear axle works across the entire TRX-4M family, including the Ford Bronco 1/18 RTR in all colours (Blue, Red, Orange, Black, White, Area 51), Land Rover Defender 1/18 RTR (Green, Light Blue, Pink, Silver, Tan, Black), Chevrolet K10 High Trail Truck (Blue, Red, Black), Ford F-150 High Trail Truck (Blue, Black, Brown), and the TRX-4MT Monster Truck variants (K10 and F150 in Red and Black), making it an essential spare for any TRX-4M owner.
- OEM Genuine Part — As an official Traxxas factory part, this axle meets all original equipment manufacturer specifications and quality standards, ensuring it performs identically to the factory axle installed in your RC crawler.
- Ready to Install — No assembly required means you can have your TRX-4M back on the trail within minutes of receiving this part, minimising downtime and getting you back to driving faster than ever.
Technical Performance
The Traxxas TRX9744 rear axle assembly represents the pinnacle of drivetrain engineering for 1/18 scale RC crawlers and trail trucks. Built to handle the specific demands of TRX-4M models, which are engineered for technical off-road driving over rocks, roots, mud, and challenging terrain, this rear axle features a robust construction using metal half shafts that resist bending and breaking under load. The bushings provide smooth, low-friction rotation, allowing the wheels to turn freely whilst maintaining structural integrity during climbing, descending, and lateral manoeuvres. The wheel hubs are precisely engineered to maintain perfect alignment with your RC car's frame and suspension geometry, critical for maintaining traction and steering response. With an M2.5x0.45 NL thread specification, the fastening systems are designed to remain secure even during extended off-road sessions with constant vibration and impact. The professional factory assembly ensures that all components are correctly torqued, aligned, and functional, eliminating the variability that can occur with home assembly. This is particularly important for the bushings and half shaft tolerances, where even slight variations can cause binding, noise, or premature wear. Whether you're running your TRX-4M on rock-crawling circuits, trail courses, or backyard terrain, this rear axle provides the reliability and performance required for consistent, trouble-free operation across a wide range of driving conditions.

Frequently Asked Questions
- Will this rear axle fit my specific TRX-4M model? — Yes, the TRX9744 is designed to fit all TRX-4M variants, including the Ford Bronco, Land Rover Defender, Chevrolet K10, Ford F-150, and all TRX-4MT Monster Truck models in any colour. If your RC crawler is a TRX-4M, this axle will be compatible.
- Do I need to assemble this rear axle myself? — No, this is a Traxxas Pro Built assembly, meaning it arrives completely assembled, tested, and ready to install directly onto your vehicle. Simply remove your old axle and bolt this one on—no tools or technical knowledge required beyond basic installation.
- What does M2.5x0.45 NL mean? — M2.5 refers to the metric thread size (2.5 millimetres), 0.45 is the thread pitch (distance between threads), and NL stands for standard or nominal length, ensuring your fasteners match OEM specifications and fit perfectly with all other Traxxas components.
- Why would I need two rear axles? — The TRX9744 package includes two complete axles, giving you a spare for backup, allowing you to swap in a fresh axle if one becomes damaged, or enabling you to maintain multiple TRX-4M vehicles. This is particularly valuable for competitive drivers or those who run their RC cars frequently.
- Is this suitable for beginners? — Yes, absolutely. Since this axle comes fully assembled, beginners don't need any mechanical skills to install it. However, this is a replacement part, not a complete vehicle, so you'll need to already own a TRX-4M to use it. If you're completely new to RC, consider purchasing a ready-to-run TRX-4M instead.
- How does this compare to the factory axle that came with my TRX-4M? — This is the genuine factory axle assembly from Traxxas, built to identical specifications and quality standards as the original equipment. If your factory axle has become worn, damaged, or broken, this replacement performs exactly the same way.
- Can I use this axle on other Traxxas models? — No, this axle is specifically engineered for TRX-4M models. Other Traxxas vehicles like the Slash, Stampede, or Rustler use different axle systems and fastening patterns, so this will not be compatible.
- Will this axle improve my TRX-4M's performance? — As a replacement part, this axle maintains your vehicle's original performance level. However, if your existing axle is worn or damaged, installing a fresh assembly will restore performance to like-new condition, eliminating any binding, noise, or play that accumulated wear may have caused.
