Traxxas Rear Stub Axle Carriers Aluminium Bearings TRX7852X

Overview

The Traxxas Carriers, stub axle (rear) (left & right) with 20x32x7mm bearings (2) and 15x24x5mm bearings (2) TRX7852X is a premium upgrade component designed for serious RC enthusiasts in the UK who demand maximum durability and performance from their monster trucks. These left and right rear stub axle carriers were completely redesigned and beefed-up to deliver extra strength where it matters most, providing the foundation for extreme-duty performance that pushes the limits of what ready to run RC vehicles can achieve. Whether you're running an X-Maxx or upgrading from an XRT, this is a genuine Traxxas factory upgrade that transforms your RC monster truck's handling characteristics and reliability during aggressive bashing sessions.

Standard equipment on the Traxxas XRT VXL-8S and XRT Ultimate models, these rear stub axle carriers can be installed on any compatible X-Maxx platform to unlock the same extreme-duty specifications and maximum strength that Traxxas engineers built into their flagship XRT lineup. This is not a cosmetic upgrade—it's a structural reinforcement that directly impacts drivetrain reliability, cornering performance, and overall chassis rigidity during high-speed runs and challenging terrain. For RC car UK buyers looking to get the absolute maximum from their brushless 8S monster trucks, upgrading to these carriers is a proven, factory-backed solution that's trusted by drivers worldwide.

Included in this package are all the essential bearings required for complete installation: two 20x32x7mm bearings for the primary load-bearing points and two 15x24x5mm bearings for secondary support. This complete bearing set ensures you can perform a full rear axle upgrade without needing to source components separately, making installation straightforward and hassle-free for experienced RC builders and technicians.

Key Features

• Redesigned and Beefed-Up Construction — These carriers were engineered specifically for extra strength, meaning they can withstand the punishment of aggressive bashing, high-speed jumps, and challenging off-road terrain without flexing or cracking like standard carriers.
• Factory XRT Standard Equipment — These are the same stub axle carriers that come standard on the Traxxas XRT VXL-8S and XRT Ultimate models, representing genuine Traxxas factory engineering and proven reliability in extreme-duty applications.
• X-Maxx Upgrade Compatibility — Whilst standard on XRT, these carriers can be retrofitted to the Traxxas X-Maxx to unlock extreme-duty performance and maximum strength equivalent to the flagship XRT platform, making it an accessible way to upgrade your existing X-Maxx.
• Complete Bearing Package Included — The kit includes both the 20x32x7mm bearings (×2) and 15x24x5mm bearings (×2) needed for installation, eliminating the need to purchase bearings separately and ensuring full compatibility with the carrier design.
• Milled from High-Grade 6061-T6 Aluminium — These carriers are precision-milled from solid blocks of aircraft-grade aluminium alloy, offering the perfect balance between lightweight construction and exceptional rigidity that reduces deflection during cornering and acceleration.
• Brilliant Anodised Finish with Laser-Etched TRX Logo — Beyond functional engineering, the carriers feature a high-quality anodised finish that resists corrosion and provides a professional appearance, with Traxxas branding laser-etched for authenticity and durability that survives countless bashing sessions.
• Premium Factory Fit and Finish — Every carrier is manufactured to exacting Traxxas tolerances with perfect factory fit, meaning installation is straightforward without requiring modification, shimming, or adjustment to achieve proper alignment and bearing preload.
• Improves Appearance and Ruggedness — The solid aluminium construction and anodised finish not only enhance the structural integrity of your RC monster truck but also dramatically improve its visual appeal, giving your vehicle a more professional, competition-grade appearance.

Technical Performance

These rear stub axle carriers represent genuine engineering advancement in RC drivetrain design. Manufactured from solid 6061-T6 aluminium—the same material used in aerospace applications—these carriers provide exceptional stiffness with minimal weight penalty. The redesign specifically addresses the weak points in standard axle carriers, concentrating material where stress is highest and reducing unnecessary bulk elsewhere. This intelligent engineering approach means the carriers resist flex during aggressive cornering, maintain precise bearing alignment under load, and transmit power more efficiently to the rear wheels. The 20x32x7mm and 15x24x5mm bearing sizes are precisely specified to work with these carriers, ensuring optimal load distribution and minimal drag. When installed on the X-Maxx, these carriers bring it up to XRT-level specifications, transforming drivetrain reliability and performance characteristics. The anodised finish isn't merely decorative—it provides corrosion resistance essential for RC vehicles regularly exposed to dirt, moisture, and challenging outdoor conditions. For UK RC enthusiasts running 8S brushless monster trucks at high speeds across varied terrain, these carriers deliver the structural integrity needed to keep your vehicle competitive and reliable through season after season of demanding use.

Frequently Asked Questions

• Are these carriers compatible with my Traxxas X-Maxx RC monster truck? — Yes, these rear stub axle carriers are specifically designed as an upgrade for the X-Maxx platform. Whilst they come standard on the XRT VXL-8S and XRT Ultimate models, they can be retrofitted to any compatible X-Maxx to upgrade it to XRT-level extreme-duty specifications and maximum strength.
• What models can use these Traxxas rear stub axle carriers? — These carriers are compatible with the Traxxas X-Maxx (all variants including the X-Maxx Belted 4WD Brushless RTR 8S in orange, blue, red, green, and the X-Maxx Ultimate Blue X and Green X editions) and the Traxxas XRT range (XRT VXL-8S in green, black, blue, and orange, plus XRT Ultimate Blue X and Green X). They also fit the X-Monster chassis.
• Do these carriers come with bearings? — Yes, absolutely. This is one of the major advantages of purchasing the complete kit. You receive two 20x32x7mm bearings and two 15x24x5mm bearings, which are the exact sizes required for proper installation in these carriers. This eliminates the need to source bearings separately and guarantees compatibility.
• What material are these carriers made from? — These carriers are precision-milled from solid 6061-T6 aluminium, the same lightweight but exceptionally strong material used in aerospace engineering. This provides the ideal balance between weight savings and structural rigidity, reducing flex whilst keeping your RC monster truck as light as possible.
• Will upgrading to these carriers improve my X-Maxx performance? — Yes, significantly. These redesigned carriers offer extra strength compared to standard components, which means improved handling during aggressive cornering, better drivetrain reliability under extreme loads, and more consistent performance. By bringing your X-Maxx up to XRT-level specifications, you're investing in durability and precision that directly translates to faster, more predictable driving characteristics.
• How difficult is installation on my RC monster truck? — Installation requires mechanical skill and proper tools, as you'll need to disassemble the rear drivetrain, remove old carriers, and install the new ones with the included bearings. However, Traxxas engineering ensures factory-perfect fit, so installation follows standard procedures without requiring modification or adjustment. We recommend following the Traxxas manual for your specific model carefully.
• Are these carriers suitable for bashers or competition drivers? — These carriers are equally valuable for both bashers and competition drivers. The extra strength and redesigned construction prevent failures during aggressive recreational bashing sessions, whilst the precision engineering and factory fit make them ideal for drivers competing in events where reliability is paramount.
