Auto body parts buying guides

How numbers work, what actually differs between OEM and aftermarket, and how to stock the categories that move fastest. Written for buyers, by the people who cut the moulds.

About the knowledge centre

Who writes these guides?
The SLCHN sales engineering desk, from the questions buyers actually ask during quotation. Nothing here is generic filler — the number formats and examples come from the catalog.
Can I reuse this content on my own site?
Ask us first and in most cases yes, with attribution. Our cross-reference data and product photography are routinely licensed to customers for their listings.
What should I read first?
If you are new to sourcing crash parts, start with the OEM number guide — everything else in wholesale body parts follows from reading numbers correctly.

Question about a specific part?

Send the OEM number or a photo — our engineers answer sourcing and fitment questions daily.
