We keep unverified dimensions visible until a drawing or measured sample resolves them.

We coordinate independent China sourcing for B2B buyers of wheel-end accessories. This site operates independently of the Eibach brand owner. Suppliers manufacture and document the goods, and buyers approve the items and their applications.
A buyer may know the vehicle and center bore while the supplier sees a ring size without the engagement depth. Either party can miss a hub shoulder that keeps the wheel from seating. Our role starts with the gap between those two descriptions.
“Which two parts have to mate, and what tells us they do?” Question we use during specification intake
We keep separate records for the buyer's application, supplier drawings and any independent checks. A documented OE cross reference can narrow the search for hub flange or ABS encoder variants. The buyer uses the corresponding drawings and sample to make the release decision. For a serviceable wheel bearing, the buyer also checks bearing preload instructions and seal lip orientation before choosing a kit.
We keep unverified dimensions visible until a drawing or measured sample resolves them.
We separate per-size volume, packaging, freight assumptions and supplier terms.
We label which party supplied, checked or approved each item of evidence.

Two line items can share a wheel-side OD and still serve different hub pilots. Distinct SKU labels and a visible drawing revision help a receiving team separate them.

A clip that appears close in a photo can move or damage a coated flange. For a valve, the rim profile and bead seat layout also affect access to the stem. The buyer can check the sample against the relevant rim and document the seating condition before accepting repeat orders.
Start with the application and the dimensions you have already measured.
