Ultima 98-515 Billet Oil Pump Harley Evolution 1992-1999 Replaces OEM 26050-92

Item Overview

Upgrade Your Evolution Engine

Maximize the life of your Evo motor with the Ultima High-Output Billet Oil Pump (P/N 98-515). Designed as a direct replacement for the factory die-cast unit on 1992–1999 Big Twin models, this pump solves the common "wet sumping" and low oil pressure issues inherent in aging stock systems. Its CNC-machined billet aluminum body offers zero flex under thermal stress, ensuring consistent lubrication delivery to your lifters and top end.

Key Features

High Flow Design: Engineered to deliver greater oil volume than stock, providing critical protection for high-performance or high-mileage engines.

Idle Pressure Stability: Specifically valved to maintain oil pressure at low RPMs, preventing the oil light from flickering in stop-and-go traffic.

Billet Construction: Machined from 6061-T6 aluminum, this pump is significantly stronger than OEM die-cast zinc pumps, which are prone to scoring and warping.

Show Quality Finish: Features a mirror-polished finish that looks great on custom builds or open belt drive setups.

Complete Kit: Includes the pump assembly, supply and return gears, shaft keys, snap rings, check ball, spring, and all necessary mounting hardware/gaskets.
