G-RCO-TRX011

Overview

The RCO Gear Set, Metal, Low Ratio TRX-4M (G-RCO-TRX011) is a premium upgrade component designed for UK RC enthusiasts who demand superior performance and durability from their trail trucks. This high-quality metal gear set replaces the stock plastic components found in Traxxas TRX-4M models, offering a complete transmission overhaul that transforms your RC crawler's strength and reliability. Whether you're a dedicated RC car UK hobbyist tackling challenging terrain or someone looking to extend the lifespan of your investment, this gear set delivers the performance upgrade you need.

Built by RC Overhaul, a recognised manufacturer in the RC community, this gear set maintains the original 16.6:1 reduction ratio whilst upgrading every critical component to metal construction. The complete package includes not just the gears themselves, but also new idle shafts, brass bushes, and rubber shielded bearings, making this a truly comprehensive transmission refresh. This is the ideal solution for RC enthusiasts who want to push their TRX-4M harder without worrying about drivetrain failures.

If you own a Traxxas TRX-4M in any of its variants—whether it's the Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150—this metal gear upgrade is specifically engineered for your model. The upgrade maintains compatibility with your existing setup whilst providing the strength and load capability your trail truck deserves, making it an essential addition to any serious RC car UK collection.

Key Features

• Metal Construction Throughout — All gears are manufactured from durable metal rather than plastic, dramatically increasing their ability to withstand the stresses of off-road RC driving and reducing the risk of catastrophic drivetrain failure during intense trail runs.
• Maintains 16.6:1 Reduction Ratio — This upgrade preserves your TRX-4M's original gear ratio, ensuring your truck maintains its intended performance characteristics whilst gaining durability, so you get stronger without losing any driving feel or speed characteristics.
• Complete Transmission Overhaul Package — This isn't just a gear upgrade; it's a full transmission refresh including idle shafts, a layshaft, brass bushes, and rubber shielded bearings, meaning you can completely rebuild your gearbox in one purchase without hunting for individual components.
• Enhanced Gearbox Strength — The combination of metal gears with upgraded supporting components significantly increases the overall load capacity of your transmission, allowing you to tackle more aggressive terrain and driving styles with confidence.
• Improved Load Capability — Metal gears distribute stress more effectively than plastic equivalents, meaning your TRX-4M can handle heavier impacts, steeper inclines, and more demanding obstacles without experiencing gear stripping or transmission damage.
• Rubber Shielded Bearings — Six high-quality rubber shielded bearings are included, protecting your drivetrain from dirt and moisture contamination whilst maintaining smooth rotation, essential for reliability in outdoor UK terrain.
• Brass Bushes Included — Three brass bushes provide superior wear resistance compared to plastic alternatives, ensuring your transmission operates smoothly for extended periods between services.
• Professional-Grade Engineering — Manufactured by RC Overhaul to precise specifications, this gear set represents serious engineering for hobbyists who refuse to compromise on quality or reliability.

Technical Performance

The RCO Gear Set represents a significant engineering upgrade for your TRX-4M's transmission system. The metal construction of all gears—comprising one 11-tooth pinion, two 40-tooth gears, and one 37-tooth gear—ensures that the drivetrain can withstand the repetitive stresses of trail crawling without degradation. The 16.6:1 gear ratio is carefully maintained to preserve your truck's acceleration and speed characteristics whilst the metal construction increases torque handling capacity. The inclusion of four idle shafts and one layshaft, along with three brass bushes, means every component in the transmission chain benefits from this upgrade. The rubber shielded bearings are engineered to eliminate wobble and maintain precise gear mesh, critical for smooth operation and reduced mechanical noise. This level of engineering ensures your TRX-4M's transmission operates at peak efficiency whether you're crawling over rocky terrain, navigating water crossings, or bashhing at speed on UK trails.

What's in the Box

• 1 x 11-tooth Metal Pinion Gear
• 2 x 40-tooth Metal Gears
• 1 x 37-tooth Metal Gear
• 4 x Idle Shafts
• 1 x Layshaft
• 3 x Brass Bushes
• 6 x Rubber Shielded Bearings

Compatibility

This gear set is engineered for all Traxxas TRX-4M variants, including the Ford Bronco (available in Black, White, Area 51, Blue, Red, and Orange finishes), Land Rover Defender (Silver, Tan, Black, Green, Light Blue, and Pink variants), Chevrolet K10 High Trail (Red, Black, and Blue options), and Ford F-150 High Trail (Blue, Black, and Brown finishes). Before installation, verify your truck's model number matches one of the compatible TRX-4M variants listed to ensure proper fitment and operation.

Frequently Asked Questions

• Will the RCO metal gear set improve my TRX-4M's performance? — This upgrade doesn't increase speed or acceleration since it maintains the original 16.6:1 ratio, but it dramatically improves reliability and strength. You'll experience smoother drivetrain operation, reduced noise, and most importantly, the confidence to drive harder knowing your transmission can handle the abuse. For UK trail driving where durability matters more than raw speed, this is a worthwhile upgrade.
• Is this suitable for beginners or do I need advanced skills to install it? — This is an intermediate-level upgrade requiring disassembly of your TRX-4M's gearbox and reassembly with new components. If you're comfortable performing maintenance on your RC car and have basic mechanical knowledge, this is manageable. However, if you've never worked on RC transmissions before, we recommend seeking assistance from experienced RC enthusiasts or visiting a specialist for installation to ensure everything is set up correctly.
• How much does this upgrade actually improve durability? — Metal gears are significantly stronger than plastic, offering vastly improved resistance to stripping, breaking, and deformation. Most users report their upgraded transmissions lasting several times longer than stock, particularly if they drive aggressively or regularly encounter rough terrain. The inclusion of quality bearings and bushes further extends component lifespan and improves overall reliability.
• What makes this better than other gear upgrades for the TRX-4M? — This is a complete package rather than individual gears; you get new idle shafts, bushes, bearings, and all necessary components in one purchase. Many competitors only supply the gears themselves, leaving you to source supporting components separately. Additionally, RC Overhaul's engineering ensures all components work together harmoniously, maximising durability and performance.
• Do I need any special tools to install this gear set? — You'll need basic RC tool sets including hex keys, screwdrivers, and ideally some light mechanical lubricant designed for RC transmissions. Access to a transmission/gear box stand or vice is helpful for holding the truck stable during disassembly, though not essential. Detailed instruction manuals are recommended, and many UK RC forums have installation guides specific to TRX-4M gearbox work.
• Will upgrading my gears reduce running time or battery life? — No, upgrading to metal gears actually improves efficiency slightly by reducing internal friction and heat generation. You may notice marginal improvements in battery runtime due to smoother drivetrain operation, though the difference is typically minimal. The real benefit is reliability—you're less likely to experience mid-run failures that would cut your session short.
