Case Study: Connecting Rod Supply for a dealership group in Europe

Source:Case / Time:2026-09-18

Connecting Rod for A dealership group in Europe

A dealership group came to us with a connecting rod programme for Europe. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • Inconsistent hardness between lots
  • Lead time that slipped twice before bulk started
  • Documentation that arrived after the container shipped

ClientA dealership group
MarketEurope
Volume2,000 pieces across 6 specifications
Base materialCast Iron
Sampling rounds3
Delivery window4 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Cast Iron and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Connecting Rod production run

Result

  • 2,000 pieces delivered inside the 4-week window.
  • Unit cost held within 3.0% of the original quotation.
  • Inspection-related rejection stayed under 2.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Planning something similar?

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
