Key Features

• Front and Rear Gearbox Housing — This component serves as the protective enclosure for the critical differential and gear assembly in your TRX-4M, shielding internal drivetrain components from dirt, mud and impact damage whilst maintaining precise alignment for optimal power transfer and handling characteristics.
• Complete Hardware Package Included — The housing comes supplied with all necessary fasteners including 2x 4mm ball cup studs with threadlock compound pre-applied, 4x 2x8mm ball cup studs, and 2x 3x16mm mounting pins, ensuring you have everything needed for a complete installation without hunting for compatible hardware.
• Threadlock Applied to Critical Fasteners — The supplied 4mm ball cup studs come with threadlock compound already applied, which prevents vibration-induced loosening during rough terrain driving and rock crawling, a critical consideration when pushing your RC crawler to its limits.
• Genuine Traxxas OEM Component — As an official Traxxas spare part manufactured to exact original specifications, this gearbox housing guarantees perfect fit and function with your TRX-4M model, maintaining the vehicle's structural integrity and performance characteristics.
• Universal Compatibility with TRX-4M Family — This housing is fully compatible with all TRX-4M variants including the Ford Bronco trail truck and monster truck versions, the Land Rover Defender in all colour options, the Chevrolet K10 trail and monster truck variants, and the Ford F-150 trail and monster truck models, making it an essential spare for multi-model collectors.

Technical Performance

The Traxxas TRX-4M gearbox housing represents the pinnacle of RC drivetrain engineering, designed specifically to house and protect the differential and gear assemblies that translate motor power into controlled wheel rotation. This component must maintain absolute precision in its tolerances whilst withstanding substantial mechanical stress from rock crawling, high-torque launches, and terrain impacts. The housing geometry is optimised for the TRX-4M's legendary low-speed crawling capability, ensuring that torque is transmitted smoothly and efficiently through the drivetrain. The supplied fasteners, including the pre-threadlocked 4mm ball cup studs and the additional 2x8mm studs plus 3x16mm pins, are all engineered to Traxxas specifications to ensure they remain secure during the vibration and shock loads inherent in RC trail driving. The inclusion of threadlock compound on critical fasteners demonstrates Traxxas's understanding of real-world RC vehicle maintenance, where vibration-induced fastener loosening has traditionally been a challenge for serious crawlers. Whether you're running the TRX-4M on rocky terrain, muddy trails, or technical obstacle courses, this gearbox housing maintains the dimensional accuracy and structural integrity essential for consistent performance. The component's design also ensures adequate clearance for internal gear rotation and differential operation, preventing bind or drag that could compromise efficiency or cause overheating during extended driving sessions. For UK RC enthusiasts engaged in competitive crawling or serious weekend bashing, this genuine Traxxas component is an investment in reliability and consistent performance that keeps your TRX-4M trail truck or monster truck running at its best.

The supplied hardware and fasteners are all standard sizes compatible with common hex drivers and tools found in any RC enthusiast's toolkit.
• What makes this an essential spare part for TRX-4M owners? — The gearbox housing protects the critical drivetrain components that deliver power from your motor to the wheels. During aggressive rock crawling, high-speed bashing, or impacts against obstacles, this housing can sustain damage that compromises the vehicle's performance or causes internal drivetrain problems. Having a genuine replacement housing on hand means you can quickly restore your TRX-4M to full performance rather than facing lengthy downtime whilst waiting for repairs.
• Does this housing come with all the hardware I need? — Yes, the TRX9747 includes everything necessary for installation: 2x 4mm ball cup studs with threadlock already applied, 4x 2x8mm ball cup studs, and 2x 3x16mm mounting pins.

• What is threadlock and why does Traxxas pre-apply it? — Threadlock is a special compound that prevents fasteners from vibrating loose during use. The pre-applied threadlock on the supplied 4mm ball cup studs reflects Traxxas's experience with competitive RC driving, where vibration from terrain impacts and motor torque can cause screws to gradually loosen over time. This pre-application saves you a step during assembly and ensures optimal security from day one.
• Can I use this housing with different gear ratios? — Yes, the gearbox housing design accommodates standard gears used in the TRX-4M platform, providing flexibility for different driving styles and terrain types. Whether you're running the standard gear set for all-around versatility or upgrading to alternative ratios for specific driving conditions, this housing maintains compatibility with your chosen drivetrain configuration.
• How does this relate to the TRX-4M Two-Speed Transmission? — The TRX-4M Two-Speed Transmission (sold separately) is an advanced upgrade that adds a manually selectable high and low gear capability to your crawler, perfect for rock crawling with incredible torque in low range.
