Send Your Core — Mail-In Rebuild Service

Rebuilding your 2-stroke crank is easy from anywhere in the country. Here's how.

Get a quote

Contact us with your make, model, year and what the crank needs. We'll confirm pricing and give you shipping details.

Remove the crankshaft

Pull the crank from your engine, or send the complete bottom end if you'd rather we split the cases. Either works.

Clean and tag it

Wipe off heavy grease and oil. Include a note with your name, phone, email, and engine details so your core never gets mixed up.

Package it securely

Wrap the crank well and box it so the journals and rod ends can't bang around in transit. Use a sturdy box and plenty of padding.

Ship it to us

Send it to Competitive Crankshafts, 507 E 45th Street, Unit 300, Garden City, ID 83714. We recommend insuring the package.

We rebuild & return

We rebuild, weld, true and balance your crank, verify it, and ship it back ready to run.
