Description
The ARP 134-7901 oil pump drive shaft kit is listed for Chevrolet Small Block. The shaft transfers drive to the oil pump, so engine configuration, shaft length and engagement at both ends are central to correct selection.
Technical Highlights
- Manufacturer part number: 134-7901
- Application/configuration: Chevrolet Small Block
Selection Guidance
Block deck height, oil-pump design and the drive arrangement can change the required shaft geometry. Select the exact application rather than substituting a shaft based only on engine displacement.
Confirm the block and oil-pump combination, including any raised or tall-deck requirements stated for the part.
Installation Considerations
Trial-fit the pump and drive assembly to check engagement, retention and free movement. Complete the engine builder’s oil-system checks and priming procedure before initial startup.
