Source wheel-end parts with Perfect Equipment
Need hub-centric rings, clip-on wheel weights or related service parts from China? We coordinate sourcing around your fitment details, quantity and destination, so you can compare supplier offers on the same basis.
What goes into a usable brief?
| Part | Send with your brief |
|---|---|
| Hub-centric ring | Wheel center bore and vehicle hub pilot in mm, ring depth, chamfer and material. An example size pair is 66.6 mm OD × 57.1 mm ID. Measure both interfaces on the application. |
| Clip-on weight | Rim material, flange profile, weight increment in grams, coating and target market. Ask whether the clip drawing matches the flange before comparing price. |
| Adhesive weight | Segment mass, strip width, backing and wheel finish. Request application and conditioning instructions for the supplier’s specific adhesive. |
| Valve service kit | Stem length, valve hole diameter, seal seat, thread and the items expected in each kit. |
| Product | Send with your brief |
|---|---|
| Alloy or commercial wheel | Rim diameter and width, PCD or bolt pattern, wheel offset (ET), center bore, load rating, finish, vehicle and target market. Add rim construction for commercial applications. |
| Road or specialty tire | Size, load index, speed rating, tread pattern, operating surface, quantity and destination port. For off-road tires, include duty cycle and casing or cut-resistance priorities. |
| Product | Send with your brief |
|---|---|
| Wheel hub assembly | OE cross reference, VIN or vehicle details, hub flange, ABS encoder ring and sensor interface, and installation hardware. |

Questions before you order
When does a catalog ring make sense?
A catalog size can simplify replenishment if bore, pilot and seating depth already match. A custom ring can address a different chamfer or depth, with a new drawing, sample approval and supplier-specific MOQ.
What should a clip-on sample prove?
Agree on the wheel flange profile and fit-check procedure. Note the rim material, finish and mass marking. A sample fit on one profile leaves other profiles unverified.
When should I compare more than one supplier?
One supplier simplifies revision control and carton labeling. A second option can fill size gaps or provide continuity, with extra work to align tolerances, records and packaging before mixed-container loading.
Does a supplier certificate cover my SKU?
Check whether the record describes the supplier’s quality system or a product-specific test or approval. Ask for its issuer, location, model scope and target market before relying on it.
Have a part number or a measured sample?
Send either one with your vehicle application and destination. Flag dimensions you still need to verify.
