Overview

The ARRMA Short Course Side Guard Set Z-AR320421 is an essential upgrade for RC enthusiasts looking to protect their short course truck from the rigours of off-road terrain. Designed specifically for ARRMA's Infraction 4X4 models, these side guard extenders are precision-engineered to safeguard the centre of your vehicle from dust, dirt, stones, and mud that inevitably get thrown up during aggressive driving. Whether you're a seasoned RC car UK hobbyist or someone just discovering the world of ready to run RC vehicles, this protective upgrade is a practical investment that extends the lifespan of your chassis and internal components.

These composite side guards mount above the chassis on both sides of the vehicle, creating a protective barrier that shields vulnerable areas from terrain hazards. The robust construction means your RC short course truck can tackle more challenging environments with confidence, knowing that critical components are protected from debris ingress. This is particularly valuable if you frequently bash your vehicle outdoors or compete in off-road RC events where durability and component protection are paramount.

Built with the same quality standards you'd expect from ARRMA, a recognised leader in high-performance RC vehicles, this side guard set represents genuine factory engineering rather than an aftermarket compromise. The set includes both upper and lower guards for both sides of the vehicle, providing comprehensive coverage that serious RC enthusiasts demand. Whether you're upgrading an existing truck or completing a new build, this accessory is a worthwhile addition to any RC model collection.

Key Features

  • High-Quality Composite Material — These side guards are moulded from resilient composite material that provides excellent impact resistance and durability whilst remaining lightweight, ensuring your RC vehicle's performance isn't compromised by added weight.
  • Four-Piece Complete Protection Set — The package includes both upper and lower side guards for the left and right sides of your vehicle, delivering comprehensive protection across the entire vulnerable side profile of your short course truck.
  • Above-Chassis Mounting Design — The guards position themselves above the chassis, creating an effective barrier against dirt ingress whilst maintaining clearance for suspension movement and preventing interference with the vehicle's handling characteristics.
  • Dirt and Debris Protection — Specifically engineered to shield the centre of the vehicle from whatever the terrain throws at it, these guards reduce dust, dirt, stone, and mud from reaching internal components, reducing maintenance requirements and extending component lifespan.
  • Factory-Designed for Perfect Fitment — As genuine ARRMA parts, these guards are engineered to fit perfectly on compatible models without requiring modification, drilling, or additional fabrication work.
  • Easy Installation and Replacement — The modular design means these guards can be easily installed, removed, or replaced if damaged, making maintenance and repairs straightforward even for newer RC enthusiasts.

Technical Performance

The ARRMA Short Course Side Guard Set represents a straightforward yet effective engineering solution to a common problem facing RC bashers and competitors: protecting your vehicle's vulnerable side areas from terrain hazards. The composite material chosen for these guards strikes an excellent balance between impact resistance and weight, ensuring protection without compromising the performance envelope of your short course truck. The four-piece construction—upper left, upper right, lower left, and lower right—provides layered protection that addresses multiple debris trajectories, from low-slung rocks striking the lower side profile to dust and stones kicked up to the mid-chassis area. The moulding process creates a resilient finish that can withstand repeated impacts from obstacles and debris without cracking or degrading, and the material's composition means it won't absorb moisture or require special maintenance. The mounting system is designed to integrate seamlessly with the ARRMA Infraction platform, ensuring that no modifications to your chassis or suspension are required. This is a performance-focused accessory for serious RC operators who understand that preventative protection is more cost-effective than repairing damaged electronics, bearings, and components after they've been exposed to harsh terrain.

Frequently Asked Questions

  • Which ARRMA models are compatible with the Z-AR320421 side guard set? — This side guard set is specifically designed and tested for the ARRMA Infraction 4X4 1/8 3S BLX Resto-Mod Truck in both Teal and Gold colour variants. The part numbers for compatible vehicles are C-ARA4315V3T2 and C-ARA4315V3T1 respectively. Always verify your vehicle's exact model number before ordering to ensure compatibility.
  • What material are these side guards made from? — These side guards are moulded from high-quality composite material, which provides excellent durability and impact resistance whilst remaining lightweight. The composite construction resists cracking and degradation, even with repeated exposure to rough terrain and debris impacts.
  • Will these guards interfere with my vehicle's suspension or handling? — No. The guards are specifically designed to mount above the chassis in a way that doesn't interfere with suspension movement, steering geometry, or overall vehicle handling. They sit outside the suspension envelope, providing protection without affecting performance characteristics.
  • How do I install the ARRMA side guard set? — These are genuine factory parts engineered for direct fitment to compatible ARRMA models, meaning they integrate with your vehicle's existing mounting points without requiring modification or drilling. Detailed installation instructions are typically provided, and the modular design allows easy installation by users of all skill levels.
  • Will the side guards increase my vehicle's weight significantly? — The composite material is lightweight by design, so the weight addition from the four guards is minimal and won't noticeably impact your short course truck's acceleration, top speed, or overall performance characteristics.
  • What happens if I damage one of the guards? — The modular four-piece design means individual guards can be replaced separately without purchasing the complete set again. This makes repairs economical and straightforward if any guard sustains damage during use.
  • Do these guards protect against all types of terrain debris? — These guards are engineered to protect against the most common hazards encountered in off-road RC bashers including dust, dirt, stones, and mud. However, no guard system can protect against all possible impacts, so continued regular maintenance of internal components remains important.
  • Are these guards adjustable? — These are fixed-mount guards designed for optimal protection and fitment on the ARRMA Infraction platform. They mount at specific positions above the chassis and are not adjustable, ensuring consistent protection and handling characteristics.
