Core RC Schumacher CAT K1 Aero Spares & Parts

Keep your Schumacher CAT K1 Aero running at its best with our dedicated spares range. From genuine Schumacher replacement parts to compatible upgrades from Core RC and MIP Sch, you'll find belts and pulleys, diffs and slipper parts, spur gears, bearings, suspension arms and hubs, driveshafts, steering components, shock towers, chassis plates, and the screws and turnbuckles that tie it all together.

Need a quick fix before race day? We hold large UK stocks for fast dispatch, with next day delivery options available, and our friendly, knowledgeable team is on hand to help you pick the right part.

Top tips: match items to your manual's part numbers for the CAT K1 Aero, double-check belt/pulley tooth counts, and refresh consumables like bearings, diff balls, oils and springs regularly for consistent performance. Looking to tune handling? Explore Core RC shock oils and springs, and MIP Sch driveline hop-ups for durability and efficiency.

Use the filters to browse by brand or part type, and if you can't see the exact piece you need, get in touch - we'll be happy to help. For more Schumacher platforms and general tools, see our main Schumacher category.
