Core RC Schumacher Cat K1 Spares & Upgrades

Core RC Schumacher Cat K1 Spares & Upgrades

Keep your Schumacher Cat K1 at peak performance with our comprehensive range of genuine Schumacher Cat K1 spares and race upgrades. From belts, pulleys and layshaft spurs to gear diffs, bearings and turnbuckles, you’ll find the essentials for routine maintenance as well as performance tuning. Replace worn wishbones, hubs and CVDs, refresh shock towers, springs and pistons, and stock up on screws, shims and body hardware for race‑day fixes.

We stock official Schumacher parts alongside quality accessories from Core RC and MIP Sch, including oils, tools and drivetrain components that fit the Cat K1. Use the filters to browse by sub‑assembly, brand or part number, and check the product notes for model compatibility.

Tips: keep belts correctly tensioned and free of debris; rebuild diffs and shocks regularly for consistent handling; and carry spare front arms, spur gears and hub carriers—common items to have in your pit box. If you’re unsure which part you need, our knowledgeable team is happy to help.

With large UK stocks and friendly service, Wheelspin Models gets you back on track fast. Order today for speedy dispatch and convenient delivery options, including next‑day to most UK addresses.
