RC enthusiasts with Arrma vehicles, this aluminum transmission gearbox is a serious upgrade for your RC car!

Specifically designed for 1/10 scale Big Rock 3S BLX, Senton 3S BLX, Granite 3S BLX, and 1/8 scale Typhon 3S BLX models, this navy blue anodized gearbox replaces the stock plastic unit with durable 6061-T6 aluminum.

The sliding motor position design is genius - it allows for fine-tuning your gear ratio using different pinion sizes while keeping everything sealed against sand and dust.

The precision CNC machining means perfect fitment and smooth operation, while the anodized finish looks fantastic and resists corrosion.

Installation is straightforward for replacing worn or broken stock parts, and the improved durability means you'll spend less time repairing and more time driving.

The sealed design is particularly valuable for off-road bashing where dirt and debris can quickly destroy standard gearboxes.

The navy blue color adds a custom look to your RC vehicle while providing the strength needed for aggressive driving.

Whether you're upgrading for better performance, replacing a damaged gearbox, or just want the reliability of metal components, this aluminum transmission delivers professional-grade performance.

Your RC car will handle more power, last longer between maintenance, and look seriously cool with this upgraded gearbox.

It's one of those mods that actually makes a noticeable difference in both reliability and appearance.
