eBay vs Amazon for Truck Parts: What Actually Sells

Amazon converts when the part has a stable OEM number and ASIN match. Think new Bendix brake drums, Cummins fuel filters, LED headlight assemblies.

eBay converts when the part is used / rebuilt / salvage, or when the compatibility list is wider than one OEM. Cummins ISX turbos, Eaton Fuller 18-speed transmissions, Cascadia hoods.

Export both when you're not sure. BTP Pro allows 5 of each per month. Enterprise is unlimited.

Measure sell-through, not impressions. eBay hides half the impression story and Amazon hides even more. If a listing doesn't sell in 30 days, re-list with a new title.
