Hey RC enthusiasts! Upgrading your Tamiya Mercedes-Benz Unimog 425 (CC-01 chassis, item #58609)? This FastEddy sealed bearing kit is exactly what you need to make your ride smoother and faster. The kit includes all the bearings to replace the stock bushings: (3) 5x8x2.5mm, (11) 5x11x4mm, (2) 6x12x4mm, and (2) 10x15x4mm bearings. They're sealed to keep out dirt and grit, which means less friction, better performance, and longer life for your drivetrain. Just a heads-up—bearing sizes can sometimes vary depending on your model's production date or any hop-ups you've installed, so it's a good idea to double-check your RC before ordering. But FastEddy tries to keep these kits updated and accurate. Installation is straightforward if you're comfortable working on your RC. Swapping to bearings reduces wear, improves efficiency, and just makes everything run nicer. A must-have upgrade for any serious Tamiya builder or hobbyist looking to get the most out their Unimog!
