| Grade | Typical parts | When it pays |
|---|---|---|
| Genuine Cat | Injectors, high-pressure pumps, ECUs, hydraulic pump cores, sensors | Machines in warranty, engine overhauls, high-duty positions — where a wrong part costs most |
| Quality aftermarket | Filters, seal kits, belts, teeth, pins and bushings, hoses | Periodic service items — material spec (PU/NBR, Shore A hardness) matters more than the logo |
| Structural / cosmetic | Covers, steps, guards, panels | Price and lead time decide |
Five checks prevent most aftermarket failures: ① material matches the spec of the position; ② hardness rating stated (seals); ③ surface finish on seal lips and bushings; ④ labeled packaging with part-number cross-reference; ⑤ the supplier asks for your serial number before quoting. Our aftermarket wear parts carry cross-referenced labels so you verify before fitting.
Three cases: ① warranty coverage on the machine; ② one-shot engine work — pulling an engine twice costs more than any savings; ③ electronics — mismatched ECUs and sensors can refuse to run at all. Everything else: a quality aftermarket part on a correct service interval gives the best cost per hour. Ask us for both grades on any quote and compare on the same basis.

The label on each part states the grade and part-number cross-reference. Match it against the PI before fitting, or send us a photo for a double check.
