Hey SCX24 crawler fans! If you're beating up your rig on the trails, the stock plastic drive shafts can be a weak point. This is a simple but super effective upgrade. It's a pair of steel drive shafts specifically made for the Axial SCX24 90081 1/24 scale RC crawler. The set includes the shafts you need for the front, rear, and center. The size is 64mm + 32mm, which is the correct fit for that 90081 model. They're made from solid steel, which is way more durable and wear-resistant than the original plastic parts. This means less chance of them stripping, snapping, or getting chewed up when you're putting down torque on rough terrain. Installation is pretty straightforward if you're comfortable with basic RC maintenance – it's a direct replacement. Swapping to these metal shafts is one of the most common first upgrades for the SCX24 because it really improves reliability and performance. They ensure a longer lifetime and better power transfer to the wheels. Whether you're replacing broken parts or just proactively upgrading your rig, this is a smart move. They come in a simple black finish and weigh about 18g for the pair. A nice, affordable upgrade to make your tiny crawler a lot tougher.
