Quality: What Actually Matters
A final drive is a precision mechanical component. Here's what determines quality:
Quality Factor
OEM
Aftermarket (Quality Manufacturer)
Gear material
Forged alloy steel
Forged alloy steel (same grade)
Heat treatment
Case-hardened
Case-hardened
Seal type
Dual-cone floating
Dual-cone floating
Manufacturing standard
OEM internal
ISO 9001 certified
Testing
OEM internal
Pressure + spin tested
The key difference? Not the engineering — the factory. A certified aftermarket manufacturer using the same materials and processes produces a functionally identical product. The savings come from leaner operations and direct sales, not cut corners.
When to Choose OEM
Machine is under active OEM warranty (aftermarket may void it)
Highly specialized, low-volume model with no aftermarket available
Fleet contract requires OEM parts
When to Choose Aftermarket
Machine is out of warranty
You need faster delivery than OEM lead times
You're managing maintenance costs across a fleet
The OEM part is discontinued or backordered
You want the same quality at 30-50% savings
