TRX9739-GRN

Overview

Upgrade your TRX-4M RC crawler with the Traxxas Servo mount in vibrant green anodised finish. This premium aluminium servo mount is engineered to eliminate flex and significantly increase steering precision in your 1/18 scale RC trail truck. Whether you're running a Ford Bronco, Land Rover Defender, Chevrolet K10, or Ford F-150 based TRX-4M model, this chassis tune-up part delivers noticeable improvements in handling responsiveness and overall driving performance. For serious RC enthusiasts in the UK looking to enhance their trail truck's capabilities, this is an essential upgrade that transforms how your RC vehicle responds to steering inputs.

The TRX9739-GRN servo mount is built from high-grade 6061-T6 aluminium, the same material trusted across the aerospace and automotive industries for its exceptional strength-to-weight ratio. Traxxas has engineered this component to provide maximum rigidity where it matters most—at the servo mounting point—whilst keeping weight to a minimum. The bright green anodised finish isn't just for aesthetics; anodising creates a hard, corrosion-resistant protective layer that extends the lifespan of your RC parts, particularly important if you enjoy running your crawler in wet conditions or challenging terrain across the UK.

This is a direct upgrade path for owners of Traxxas TRX-4M models who are ready to take their rock crawling, trail running, and off-road RC experience to the next level. By reducing unwanted flexing in the servo mount assembly, you'll notice improved steering linearity, faster response times, and better overall vehicle control during challenging climbs and technical manoeuvres.

Key Features

• 6061-T6 Aluminium Construction — This aerospace-grade aluminium alloy is significantly stiffer than plastic alternatives, providing the rigidity needed to maintain precise steering geometry under load and during aggressive driving, which is essential for rock crawling and trail truck performance.
• Green Anodised Finish — The bright anodising process creates a hard protective oxide layer that resists corrosion, rust, and weathering, ensuring your servo mount maintains its appearance and structural integrity whether you're bashing in dry conditions or tackling wet UK terrain.
• Eliminates Servo Mount Flex — Plastic servo mounts naturally flex under steering load, causing delayed response and imprecise handling; this aluminium upgrade removes that flex entirely, providing immediate and accurate steering response every time you move the transmitter stick.
• Increases Steering Precision — With a rigid mounting platform, your servo's output is transmitted directly to the steering linkage without loss, resulting in more predictable handling, better line holding, and improved performance in both casual trail running and competitive crawling scenarios.
• Direct Compatibility with TRX-4M Models — Engineered specifically for the Traxxas TRX-4M platform, this mount integrates seamlessly with all current TRX-4M variants including the Ford Bronco, Land Rover Defender, Chevrolet K10, and Ford F-150 models, requiring no modification or adaptation.
• Stylish Appearance — Beyond functional benefits, the vibrant green anodised finish adds visual appeal to your RC trail truck, complementing many colour schemes and demonstrating attention to detail in your build.

Technical Performance

The Traxxas Servo mount TRX9739-GRN represents a significant engineering upgrade over standard plastic servo mounting solutions. Manufactured from 6061-T6 aluminium, a tempered alloy renowned for its excellent machinability, corrosion resistance, and optimal strength-to-weight characteristics, this component provides the structural rigidity demanded by serious RC crawlers and trail truck enthusiasts. The anodising process applied to the green finish creates a microscopically hard surface layer—typically 25-50 microns thick—that protects the underlying aluminium from oxidation, salt spray corrosion, and wear. This is particularly valuable for UK-based RC drivers who operate in coastal areas or during winter months when salt is used on roads. The servo mount's rigid platform eliminates the compliance found in plastic designs, where small deflections under steering load accumulate to create noticeable delays in steering response. With the aluminium servo mount installed, steering commands from your transmitter translate directly into immediate wheel movement, improving your ability to thread technical obstacles, maintain tight control during downhill descents, and execute precise manoeuvres on challenging terrain. The mount is engineered to work with the Traxxas TRX-4M 1/18 scale platform, ensuring perfect fitment and optimal performance across the entire TRX-4M model range.

Frequently Asked Questions

• Will this servo mount fit my TRX-4M RC crawler? — Yes, the TRX9739-GRN is engineered specifically for all Traxxas TRX-4M 1/18 scale models. This includes the Ford Bronco, Land Rover Defender, Chevrolet K10, Ford F-150, and TRX-4MT monster truck variants. Installation requires no modification—it's a direct bolt-on upgrade.
• What is the difference between this aluminium servo mount and the plastic version? — The key difference is rigidity. Plastic servo mounts flex under steering load, introducing compliance that delays steering response and reduces precision. This 6061-T6 aluminium mount eliminates flex entirely, providing immediate and accurate steering control. The anodised coating also offers superior durability and corrosion resistance compared to plastic.
• Will upgrading my servo mount improve my crawling performance? — Absolutely. By eliminating flex in the servo mounting system, you'll experience noticeably faster steering response, improved line holding on technical obstacles, better handling precision during climbs, and more predictable vehicle behaviour overall. These improvements are particularly valuable when tackling challenging terrain or competing in trail truck events.
• Is this suitable for beginners? — Whilst this is a tune-up part rather than a complete RTR (ready to run) RC crawler, it's an excellent upgrade for beginners who already own a TRX-4M and want to improve their vehicle's performance. Installation is straightforward, and the benefits are immediately noticeable. If you're new to RC and don't yet own a TRX-4M, you may want to start with a complete ready-to-run crawler and add this upgrade later.
• Why is the green anodised finish better than painted alternatives? — Anodising creates a hard, integrated protective layer that becomes part of the aluminium surface itself. Unlike paint, which can chip and scratch, anodised finishes are extremely durable and resistant to corrosion, making them ideal for RC vehicles that encounter mud, water, and rough handling. The bright green colour is vibrant and long-lasting.
• Can I use this servo mount with aftermarket servos? — The mount is designed for standard servo sizes compatible with the TRX-4M platform. Provided your servo matches the original TRX-4M specifications, installation will be straightforward. If you're upgrading to a high-torque servo, ensure it fits within the mount's dimensions and that the vehicle's servo saver and linkage can handle the increased steering force.
