Big Block Chev 396-454 Oil Pump Drive Shaft Suit Standard Deck Height

Big Block Chevy 396-454 Oil Pump Drive Shaft – Standard Deck Height

Upgrade your Big Block Chevy oil pump setup with Aeroflow’s heavy-duty Oil Pump Drive Shaft designed for standard deck height engines. When installing a new oil pump, replacing the stock drive shaft is highly recommended. This drive shaft features a larger diameter than OEM, engineered to reliably handle the added torque demands of increased oil pump capacity and heavy-viscosity lubricants, delivering steady oil delivery under demanding conditions.

Crafted for strength and durability, this drive shaft is molded from chrome moly 8740 and finished in black oxide to resist wear and corrosion for long-lasting performance.
