Overview

The ARRMA Diff Outdrive Steel (2) Z-AR310439 is an essential spare part for any serious RC enthusiast running ARRMA brushless vehicles. Whether you're bashing on the weekends or competing at the track, these precision-engineered steel differential outdrives are the perfect addition to your RC tool box. Designed with durability and performance in mind, they represent genuine OEM quality from one of the world's leading manufacturers of high-performance RC vehicles. If you're looking for reliable replacement parts for your ARRMA RC car UK setup, these steel outdrives deliver the toughness needed for extreme RC action.

Differential outdrives are critical components in the drivetrain of any modern RC vehicle, transferring power from the gearbox to the drive shafts with precision and reliability. The differential itself allows the driven wheels to rotate at different speeds during cornering, whilst the outdrives form the mechanical connection point. Over time, with intense driving conditions—whether that's high-speed track racing, aggressive street bashing, or rugged off-road exploration—these components can experience wear. Having quality spare differential outdrives on hand means you can keep your ARRMA vehicle in peak condition and minimise downtime.

This pack includes 2 x steel differential outdrives, providing you with either a complete replacement set or spares for future maintenance. ARRMA's commitment to precision manufacturing ensures that every outdrive features accurately machined slots that work in perfect harmony with your drive shaft, maintaining the tight tolerances that professional-grade RC vehicles demand. Whether you're piloting a 1/7 scale FELONY, INFRACTION, LIMITLESS, or MOJAVE, or running 1/8 scale models like the KRATON, NOTORIOUS, OUTCAST, TALION, or TYPHON, these outdrives offer the reliability you need.

Key Features

  • Super-Tough Steel Construction — Made from hardened steel rather than softer materials, these differential outdrives resist wear, deformation, and damage during the most intense RC action, ensuring they maintain their shape and performance characteristics over extended use and repeated impacts.
  • Long-Lasting Durability — The premium steel material provides superior longevity compared to standard components, making these outdrives a worthy investment that will serve you through countless bashing sessions, races, and maintenance cycles.
  • Precision Manufactured Slots — Each outdrive features carefully engineered slots that are machined to exact tolerances, guaranteeing consistent engagement with your drive shaft without wobble, slipping, or misalignment that could compromise drivetrain efficiency.
  • OEM Quality Parts — As genuine ARRMA components, these outdrives meet the manufacturer's exacting standards and are designed specifically to work seamlessly with ARRMA's transmission systems and differential assemblies.
  • Pack of Two — Receiving two outdrives per pack provides either a complete front and rear replacement set or enables you to keep a backup spare, ensuring you're never without essential drivetrain components.
  • Universal Compatibility — These outdrives are compatible with a wide range of ARRMA 1/7 and 1/8 scale vehicles, from street-focused models like the LIMITLESS to desert trucks like the MOJAVE, speed trucks like the KRATON, stunt trucks, and buggies.
  • Essential Maintenance Part — Perfect for carrying in your RC tool box alongside other spares, these outdrives represent the kind of consumable item that serious RC enthusiasts always keep on hand for quick roadside repairs.

Technical Performance

The ARRMA Diff Outdrive Steel (2) represents years of engineering refinement in RC drivetrain design. Steel is chosen as the material specifically because it provides superior resistance to the tremendous forces experienced in high-performance RC vehicles. Whether you're running a 1/7 scale brushless vehicle pushing maximum 6S LiPo power or an 1/8 scale model delivering intense acceleration and cornering loads, steel outdrives absorb shock loads and maintain dimensional stability better than weaker materials. The precision-manufactured slots are engineered to create a secure mechanical connection with the drive shaft splines, eliminating the play and slop that would otherwise accumulate over time and result in poor handling, noise, and eventual drivetrain failure. These components are standard parts on numerous ARRMA production models including the 1/7 FELONY 6S AVC, INFRACTION 6S, LIMITLESS 6S, MOJAVE 6S, and the complete 1/8 range including KRATON 6S, NOTORIOUS 6S, OUTCAST 6S, TALION 6S, and TYPHON 6S variants. The engineering behind these outdrives reflects ARRMA's experience building vehicles that withstand the rigours of competitive racing, professional content creation, and serious hobbyist bashing at the absolute limits of what RC vehicles can endure.

Frequently Asked Questions

  • Which ARRMA models are these steel differential outdrives compatible with? — These outdrives are standard parts for a comprehensive range of ARRMA vehicles including 1/7 scale models (FELONY 6S AVC, INFRACTION 6S AVC, LIMITLESS 6S, MOJAVE 6S) and 1/8 scale models (KRATON 6S, NOTORIOUS 6S, OUTCAST 6S, TALION 6S, TYPHON 6S, and their various versions and colour variants). Check the comprehensive compatibility list in the product specifications to confirm your specific model.
  • Why should I upgrade to steel differential outdrives? — Steel outdrives offer significantly greater durability and longevity compared to softer materials, making them an excellent choice if you frequently bash your RC car or drive it competitively. The harder material resists wear from the repeated engagement and disengagement with your drive shaft splines, maintains its dimensional accuracy longer, and ultimately saves you money by reducing the frequency of replacement.
  • How often should I replace my differential outdrives? — The lifespan depends on your driving style and conditions. Casual weekend drivers might get many months or even years from a set, whilst competitive racers or aggressive bashers might need replacements every few months. Having spare outdrives on hand means you can swap them out immediately if you notice any signs of wear, keeping your vehicle in optimal condition.
  • Are these outdrives included in my ARRMA vehicle? — Yes, these steel differential outdrives come standard on most ARRMA 1/7 and 1/8 scale vehicles, so they represent genuine replacement parts that are identical to those already installed in your model.
  • What is the difference between steel and other outdrive materials? — Steel provides superior hardness and wear resistance compared to aluminium or composite materials, making it the professional choice for high-performance RC applications where reliability and longevity are paramount.
  • Do I need any tools to install these outdrives? — Installation typically requires basic RC tools including hex keys and possibly a small press or installer tool specific to your vehicle model. Refer to your ARRMA vehicle's manual for detailed installation instructions.
