TRX9589

Overview

The Traxxas Motor mount, aluminium (upper and lower) / motor mount spacer / hardware TRX9589 is a premium replacement component designed specifically for the Traxxas Sledge 1/8 scale brushless electric monster truck. This is not just a simple motor mount — it represents engineering excellence from Traxxas, delivering the rigid, zero-flex foundation that high-performance 6s RC trucks demand. Whether you're a dedicated basher pushing your Sledge to its limits, a competitive racer demanding absolute reliability, or an enthusiast looking to upgrade and maintain your RC truck UK setup, this aluminium motor mount is the genuine OEM spare part that ensures your motor stays perfectly positioned under extreme conditions.

The Sledge platform is renowned in the RC community for combining raw power with precision engineering, and this motor mount is a critical component of that success story. When running a 2000kV brushless motor with the incredible torque output of a 6s LiPo battery system, your motor mounting system must be absolutely bulletproof. The forces generated during acceleration, cornering and especially during crash impacts are enormous, and any flex or movement in the mount can lead to gear mesh misalignment, spur and pinion damage, and catastrophic drivetrain failure. This is where the Traxxas engineers have excelled — they've crafted a solution that eliminates every weak point.

RC enthusiasts in the UK and worldwide trust Traxxas components because they're built to withstand punishment that would destroy lesser quality mounts. This aluminium motor mount for the Sledge represents the pinnacle of motor mounting technology for brushless RC trucks, combining cast aluminium construction with intelligent design features that make it the benchmark in its class.

Key Features

• Cast Aluminium Cradle Design — The motor mount features a unique cradle-style construction that completely encloses the Sledge's Velineon brushless motor, providing full-contact support across the entire motor body rather than relying on simple side plates, which dramatically increases rigidity and eliminates flex points that can develop during aggressive driving or crashes.
• Zero Flex, Zero Movement Philosophy — Traxxas engineers have eliminated every component that could introduce flex into the mounting system, ensuring that your motor stays in exactly the same position whether you're accelerating on the track, bashing in the mud, or recovering from a high-speed crash impact.
• Fixed Gear Mesh Technology — The motor mount position is set by an indexed insert that precisely establishes the correct gear mesh between the motor's pinion and the spur gear, meaning you don't have to rely on thread locker or hope that components stay aligned during hard use — the mount is engineered to maintain perfect mesh geometry.
• Dual Motor Face Security Screws — Two heavy-duty screws secure directly to the face of the motor and clamp against a cast-in stop, eliminating any possibility of the motor sliding or rotating within the mount, even under the tremendous inertia forces generated during impacts.
• Four Heavy-Duty 4mm Securing Screws — Rather than using a cantilever design with vertical plates, the mount is secured to the chassis from below using four heavy-duty 4mm screws, a design approach that completely prevents the flex and movement associated with traditional motor mount designs that extend upward from the chassis.
• Crash-Proof Design — During severe crash impacts, traditional motor mounts can shift position, leading to improper gear mesh and potential drivetrain damage; this mount's hard-mounted guide system ensures gear mesh remains locked in position regardless of impact severity.
• Fan-Ready Architecture — The aluminium mount is designed with four tapped mounting points that accept optional cooling fans, allowing you to add high-flow cooling capacity for extended summer bashers or all-day racing sessions without overheating concerns.
• Heat Sink Effect — The cast aluminium construction itself provides excellent heat dissipation, working in combination with the Velineon motor's finned can to maintain optimal operating temperatures during sustained high-performance operation.
• OEM Genuine Traxxas Component — This is the authentic factory replacement part for the Sledge, ensuring perfect fit and compatibility with the rest of your truck's system and guaranteeing that you're getting the exact same engineering that comes standard on new Sledges from the factory.

Technical Performance

The Traxxas Motor mount TRX9589 represents the absolute pinnacle of motor mounting technology for high-performance 1/8 scale brushless electric RC trucks. This isn't a component for beginners or casual users — it's engineered specifically for the Sledge's 2000kV Velineon brushless motor operating on 6s LiPo battery systems that can produce well over 100 amps of current draw. The cast aluminium construction provides holding strength that far exceeds what's needed to support the motor's weight, but more importantly, it's designed to resist the inertial forces that a motor generates during crash impacts. When your truck hits a wall at 30+ mph, the motor wants to keep moving forward due to inertia, and a weak mount will flex or shift, misaligning the gear mesh. This mount's heavy-duty 4mm securing screws and indexed positioning system ensure that doesn't happen. The cradle-style design completely encloses the motor, providing support across its entire length rather than just at the mounting flanges, which is why Traxxas engineers chose this design over simpler alternatives. The inclusion of the motor mount spacer ensures proper assembly and spacing, whilst the comprehensive hardware package includes everything needed for installation. The heat-sink effect of the aluminium construction, combined with the option to add the optional cooling fan, makes this mount suitable for extended bashers in hot weather without thermal concerns affecting performance or motor longevity.

Frequently Asked Questions

• Is the Traxxas Motor mount TRX9589 compatible with my Sledge? — Yes, this is the genuine OEM motor mount for the Traxxas Sledge 1/8 4WD brushless electric monster truck. It's compatible with all colour variants including the TRX95096-4-GRN (Green), TRX95096-4-RED (Red), TRX95096-4-BLUE (Blue), and TRX95096-4-ORNG (Orange) Sledge models. If you're unsure which version you own, check the model number on your truck documentation or contact our knowledgeable team.
• Why would I need to replace my motor mount? — Motor mounts can require replacement after hard crashes, if the indexed positioning insert becomes damaged, if securing screws become stripped, or simply as part of regular maintenance for trucks used in competitive racing or intense bashing. Having a replacement on hand is smart preparation for anyone serious about their RC truck hobby in the UK.
• Will this motor mount work with motors other than the Velineon 2000kV? — This motor mount is specifically engineered for the Sledge's Velineon 2000kV brushless motor. Using it with motors of different physical dimensions, weight, or power outputs could result in improper fit or performance. Always use the OEM-specified motor for your truck platform.
• Can I add a cooling fan to this mount? — Absolutely. The mount features four tapped mounting points specifically designed for optional high-flow cooling fans. This allows you to upgrade your thermal management for all-day summer bashing sessions without modifying the mount itself.
• What makes this motor mount better than aftermarket alternatives? — The Traxxas engineering behind this mount is specifically optimised for the Sledge's extreme power output and the inertial forces generated during impacts. The indexed positioning system, dual motor face screws, four heavy-duty 4mm chassis securing screws, and crash-proof design create a system that has no flex points. Aftermarket designs often use simpler cantilever plates that extend upward from the chassis, which flex under load and can shift during impacts, compromising gear mesh alignment and drivetrain reliability.
• Is this suitable for beginners? — This is a replacement component for existing Sledge owners rather than an introductory product. If you're new to RC and own a Sledge, you likely won't need this immediately, but having it as a spare part is wise planning for when you're ready to push your truck harder or after any crashes that might affect the mount.
• Do I need any special tools to install this motor mount? — Installation requires basic RC model tools including hex drivers for the securing screws. The indexed insert design makes positioning straightforward — it's designed to fit precisely in only one way, simplifying the installation process. If you've worked on RC trucks before, you'll find this a straightforward swap.
• Why is gear mesh alignment so critical? — Improper gear mesh between the motor's pinion and the spur gear causes increased friction, heat generation, and accelerated wear on both gears. In severe cases, misaligned mesh can cause gears to skip teeth or shatter completely during hard acceleration. The indexed positioning system in this mount eliminates guesswork and ensures perfect mesh every time.
