Arrma Outcast 8S EXB Spares & Upgrades

Arrma Outcast 8S EXB Spares & Upgrades

Keep your Arrma Outcast 8S EXB at its best with our range of genuine replacement parts and smart upgrades. Whether you’re rebuilding after a big bash or refreshing wear items, you’ll find arms, hubs, driveshafts, diffs (including EXB LSD internals), bearings, shock towers, bumpers, bodies, wheels and tyres, pinions, spurs and all the screws and shims you need. Prefer uprated hardware? Explore high-torque Spektrum servos and radio gear, precision RC Overhaul bearings, Pro-Line tyres and bodies for extra grip and style, plus Dynamite tools, greases and oils to keep maintenance quick and tidy. Tip: match part numbers from your manual (e.g. ARA-xxxxx) to guarantee perfect fit on the Outcast 8S EXB, and use threadlock on metal-to-metal fixings. 8S power is tough on drivetrains - inspect diff oils and bearings regularly for the smoothest runs. We keep large stocks ready to ship, with friendly service from our knowledgeable expert customer service team if you need advice on compatibility or setup. Fast UK delivery options include next-day on many items, so you can get back to the ramp sooner.
