TRX8982

Overview

The Traxxas Gear Set, Differential (TRX8982) is an essential drivetrain spare part designed for RC enthusiasts who demand reliable performance from their high-powered RC models. This genuine Traxxas differential gear set is specifically engineered to fit the Traxxas Maxx Slash and WideMaxx monster truck platforms, making it an indispensable component for anyone serious about maintaining their brushless RC 4WD vehicle in peak condition. Whether you're a weekend basher exploring the capabilities of your brushless RC monster truck, or a dedicated racer pushing your machine to its limits on demanding terrain, this differential gear set ensures smooth power delivery and consistent handling across all four wheels of your RC car UK setup.

Differential gears are critical to the performance of any 4WD RC vehicle, allowing the wheels to rotate at different speeds during cornering whilst maintaining traction and stability. The TRX8982 is manufactured to Traxxas' exacting specifications, ensuring perfect compatibility with your existing drivetrain and delivering the reliability you expect from Traxxas genuine parts. This is not an aftermarket compromise — it's the factory-standard component that Traxxas engineers designed for optimal performance in their brushless RC short course truck and monster truck platforms.

If you've experienced differential wear after intense driving sessions, or simply want to keep a spare set on hand for your RC hobby, the TRX8982 delivers the peace of mind that comes with genuine manufacturer parts. RC Model Shop stocks this essential spare, ensuring UK customers have fast access to authentic Traxxas components without compromise on quality or compatibility.

Key Features

• Complete differential gear set — This comprehensive kit includes everything needed for a full differential rebuild or replacement, including two output gears that handle power distribution to the wheels, four spider gears that allow for differential action during turns, two spider gear shafts that support the spider gear assembly, two output shafts that transfer power to the wheels, and two 2.5x13.8 pins that secure the assembly together, ensuring you have all components necessary for a complete repair without ordering multiple parts separately.
• Genuine Traxxas manufacture — Built to factory specifications and quality standards, these gears are manufactured using the same precision engineering and materials as the original equipment in your Traxxas vehicle, guaranteeing perfect fit, durability, and performance that aftermarket alternatives simply cannot match.
• Compatible with Traxxas Maxx Slash models — This gear set is engineered to fit the Traxxas Maxx Slash 1/8 4WD 6S brushless short course truck across all colour variants including Rock N Roll, Blue, Red, and Green versions, providing seamless compatibility and easy installation.
• Compatible with Traxxas WideMaxx monster truck — The TRX8982 also fits the larger Traxxas WideMaxx monster truck platform across all available colour options (Rock N Roll, Green, and Red), making it a versatile spare for owners of multiple Traxxas brushless RC vehicles.
• High-quality steel and composite construction — The gears and shafts utilise materials specifically selected for strength and durability, capable of withstanding the immense torque generated by 6S brushless power systems whilst maintaining smooth operation and extended service life.
• Direct replacement part — Using part number TRX8982, this is the exact same component fitted to new Traxxas vehicles, meaning you can be confident of perfect compatibility and installation without modification or adaptation.

Technical Performance

The differential is one of the most critical drivetrain components in any 4WD RC vehicle, yet it's often one of the first areas to experience wear when pushing brushless RC models to their limits. The TRX8982 gear set is specifically engineered for the extreme performance demands of the Traxxas Maxx Slash 1/8 scale 4WD 6S brushless short course truck and the WideMaxx monster truck platform. These vehicles generate significant torque from their brushless electric motor systems, and the differential must distribute that power smoothly and efficiently across all four wheels whilst allowing for the wheel speed differential required during high-speed cornering. The gear set comprises precision-manufactured components including hardened output gears that interface with the axle shafts, spider gears that enable the differential locking action necessary for straight-line acceleration, and precision-drilled shafts that maintain perfect alignment and concentricity. The two output shafts work in conjunction with the output gears to transfer power from the differential case to each wheel independently, whilst the spider gear assembly allows torque to be redistributed when wheels encounter different traction conditions. The 2.5x13.8 pins are engineered to secure the entire assembly with perfect tension, preventing movement or slippage that could compromise handling or create drivetrain play. Whether you're running at high speed across hard-packed racing surfaces or exploring technical terrain with your RC monster truck, this differential gear set maintains the precision engineering required for confident, predictable handling and maximum power transmission efficiency.

Frequently Asked Questions

• Which Traxxas models is the TRX8982 compatible with? — The Traxxas Gear Set TRX8982 is specifically designed for the Traxxas Maxx Slash 1/8 4WD 6S brushless short course truck (all colour variants: TRX102076-4-RNR Rock N Roll, TRX102076-4-BLUE, TRX102076-4-RED, and TRX102076-4-GRN) and the Traxxas WideMaxx monster truck (TRX89086-4-RNR, TRX89086-4-GRN, and TRX89086-4-RED). Do not attempt to use this part on other Traxxas models as it will not fit correctly.
• Why would I need to replace my differential gears? — High-performance brushless RC vehicles generate substantial torque, and differential gears can experience wear with heavy use, particularly if you frequently engage in aggressive acceleration, high-speed cornering, or bashing on rough terrain. Worn differential gears may manifest as grinding noises, inconsistent wheel speed, or loss of traction control. Replacing your differential gears restores smooth power delivery and ensures your 4WD RC vehicle maintains optimal handling and performance characteristics.
• Is differential replacement difficult for a beginner? — Differential replacement requires moderate mechanical skill and access to basic RC tools including screwdrivers and potentially a transmission stand. If you're experienced in maintaining your own RC vehicles and comfortable working with drivetrain components, you should be able to complete this installation. However, if you're new to RC maintenance, you may wish to consult the official Traxxas service manual or seek assistance from experienced RC enthusiasts at your local hobby shop. RC Model Shop staff can also provide guidance if you visit in person.
• Do I need to replace all the gears at once? — For best results, we recommend replacing the complete differential gear set together rather than individual components. This ensures all gears are at the same wear level and prevents premature wear on newly installed gears meshing with older, worn components. The TRX8982 provides the complete set needed for a full rebuild.
• Is this suitable for brushless RC vehicles? — Yes, this differential gear set is engineered specifically for the Traxxas Maxx Slash and WideMaxx brushless RC vehicles powered by 6S LiPo batteries. These platforms generate substantial brushless power, and the TRX8982 gears are manufactured to handle the torque output of these high-performance systems reliably and efficiently.
• How often should I maintain my differential gears? — Differential maintenance frequency depends on your usage patterns and terrain. For recreational bashing and weekend use, a full differential service every 12-24 months is typically adequate. For competitive racing or intensive high-speed use, consider servicing every 6-12 months. Always inspect your differential for any signs of noise, play, or grinding before each major driving session.
