There are different types of parts used during the repair process. At Paint & Body Perfectors, we only use parts that we can give a warranty on.
Original equipment manufacturer (OEM) parts are from the dealer/manufacturer. Aftermarket parts are cosmetically the same as OEM parts, but another manufacturer makes them.
Reconditioned (reman/recon) are OEM parts that were damaged and then repaired to be used again. Like Kind in Quality (LKQ) parts are removed from vehicles at a recycling facility and sold as assemblies to repair shops.
