Helion Criterion Spares & Parts

Find the right replacement parts to keep your Helion Criterion performing at its best. This dedicated Helion Criterion Spares section brings together genuine Helion components alongside compatible Radient electronics and hardware, so you can repair, refresh or upgrade with confidence.

Browse essentials including suspension arms, hubs, shock towers, driveshafts, diffs, spur gears and pinions, bearings, wheels and tyres, body shells, bumpers, screws and turnbuckles. Need electrics? Look out for Radient batteries, chargers, motors, ESCs and servos that suit the Criterion platform.

Not sure which part number you need? Check your manual or get in touch—our knowledgeable, friendly team are hobbyists too and happy to help. With large UK stocks held in our own warehouse, most items are ready for fast dispatch, with next day delivery options available at checkout for UK customers.

Use the filters to narrow by brand (Helion or Radient), price or sub‑category, and keep a few trackside spares on hand to minimise downtime. Quality parts fitted correctly will extend the life and performance of your Helion—shop the range below.
