Arrma Outcast 4x4 4S Spares & Parts

Keep your Arrma Outcast 4x4 4S performing at its best with our full range of genuine spares and popular upgrades. Browse suspension arms, hubs, turnbuckles, driveshafts, diff gears, spur and pinion gears, bearings, shock towers, bumpers, body posts and hardware, plus wheels, tyres and body shells. We also stock electronics and consumables from trusted brands, including Spektrum ESCs, motors, servos and receivers, Dynamite tools and chargers, ProLine tyres, and Losi shock oils and lubricants.

Use your manual or exploded diagram to match part numbers (e.g. ARA-xxxx) and check product notes for V1/V2 compatibility such as slipper versus centre diff. You can filter by brand or sub-category to find exactly what you need for fast repairs or a weekend refresh.

Top tip: keep a few high-wear items like arms, hub carriers, bearings and pinions in your pit box, and use threadlock on metal-to-metal fixings. Fresh shock oil and diff fluid can transform handling and extend component life.

With large stocks, friendly service from our knowledgeable team, and fast UK delivery options including next day, Wheelspin Models makes keeping your Outcast running simple. Not sure what fits? Get in touch and we’ll be happy to help.
