Eibach wheel-end sourcing, specified at the interface

Compare hub centric rings, clip-on wheel weights and tire valves from China against the same fitment brief. We coordinate independent B2B sourcing and keep open fitment questions visible through sampling.

Start with the part interface

Three common purchasing briefs with different dimensions to lock before quotation.

Dimensions a price sheet can hide

Hub to wheel

Center bore and pilot
Record both diameters, engagement depth and chamfer on the drawing. A ring can bottom out on a radius before the wheel sits flush.
Wheel fitment
Record pitch circle diameter (PCD), wheel offset (ET), rim diameter and width, load rating, finish, vehicle and target market. A locating ring leaves those wheel specifications unchanged.

Service components

Balance weight
List clip contour, rim material and coating, wheel clearance and gram increments. Request sample clips against the actual rim flange.
Valve and hardware
Supply valve-hole diameter, seat profile, working pressure and TPMS interface. For fasteners, add thread pitch, seat shape, engagement and finish.

Procurement sequence

Four decisions before release

  1. 01

    Fix the specification revision

    Set the dimensions, units and buyer-approved mating components. Keep any measurement still pending on the RFQ.

  2. 02

    Normalize the supplier replies

    Compare the same drawing revision and quantities. Separate tooling, packing, sample charges and the Incoterm with its named place.

  3. 03

    Review a sample

    Ask for measured center bore, pilot and chamfer dimensions against the agreed drawing. If the brief covers a wheel assembly, agree how to record radial runout and lateral runout. Record any difference before the buyer releases the order.

  4. 04

    Coordinate inspection and shipment

    Carry the accepted sample reference into the inspection brief. Reconcile carton quantities, lot codes and the packing list before handoff.

What your buying team needs to see

Importers

Compare landed-cost inputs and the carton mix by SKU.

Distributors

Use separate labels for rings with a shared OD and different IDs.

Repair networks

Set clip fit and valve access around the rims already in service.

Catalog teams

Keep measured interfaces separate from application cross references.

Quality teams

Match measurements and deviations to the sample revision.

Fleet buyers

List vehicle variants by axle before aggregating quantities.

Questions before the first RFQ

What are hub centric rings used for?

They locate a compatible aftermarket wheel on the vehicle hub pilot during installation. Check both mating diameters, pilot engagement and shoulder clearance before choosing a ring.

Should I source aluminum or polymer rings?

Compare the candidate material at the measured operating temperature and check removal after exposure to moisture and road salt. Ask the supplier for the compound or alloy, tolerance and application limitations.

Can we use the stocked size nearest to our drawing?

Ask for a stocked drawing and compare its tolerance stack and seating depth. A custom geometry may resolve a mismatch but introduces sampling, tooling or quantity commitments that must be priced separately.

Can I compare minimum orders across suppliers?

Yes, after separating the minimum for each size and finish from the order-level minimum. Have each supplier state price breaks and the event that starts its quoted lead time.

First quotation

Send the line that is hardest to compare

One complete line item gives suppliers a common reference before you send a full size list.

  • Share the mating dimensions in millimetres.
  • State the quantity per size and the destination port.
  • Mark dimensions you still need to verify.
