Ultima 98-507 High Flow Oil Pump Harley Twin Cam 2007-2012 96" 103" Billet New
Item Overview
Upgrade your engine's reliability with the Ultima High-Output Billet Oil Pump (P/N 98-507). Designed specifically for 2007–2012 Harley-Davidson Twin Cam engines and 2006 Dyna models, this performance pump addresses common stock lubrication issues such as "wet sumping" and low idle oil pressure. It replaces the factory die-cast unit with a precision CNC-machined billet aluminum body, providing superior structural integrity and consistent oil delivery under all operating conditions.
Key Features & Benefits
High Volume & Pressure: Engineered to deliver significantly more oil volume and pressure than the stock OEM pump, ensuring critical lubrication reaches the top end and cam chest.
Idle Protection: Valved to maintain higher oil pressure at idle RPMs, which helps prevent bearing damage during stop-and-go riding.
Billet Durability: The 6061-T6 billet aluminum construction is far more rigid than stock die-cast pumps, eliminating the flex and distortion that can lead to internal scoring or failure.
Sump Prevention: improved scavenging capacity evacuates oil from the crankcase more efficiently, reducing drag on the flywheel and preventing oil blow-by at the air cleaner.
Complete Kit: Includes the complete pump assembly, supply and scavenge gerotors, all necessary gaskets, O-rings, snap ring, shaft key, and mounting hardware.
