How the core return works

There's no core charge when you order — nothing is added at checkout. After your new part is installed, ship your old part back to us within 30 days — return shipping is on you:

OK Speedline Auto — Core Returns
4600 W Chicago Ave, Chicago, IL 60651

Your core must be the same year, make, and model as the part you purchased. Cores that are bent, broken, or missing parts will not be accepted — no exceptions.

Once your acceptable core arrives, your lifetime warranty is activated. If we don't receive your core, the part carries a 30-day warranty instead of the lifetime warranty — and you're still never billed a core charge.
