Overview

The MMR Billet Oil Pump and Crankshaft Gears are a set of high-performance internal engine components. This combo kit includes MMR Billet Oil Pump gears part# 400224 and MMR Billet Crankshaft Gear 467892.
Show original supplier description
The MMR oil pump gears are a high-strength billet steel upgrade designed to replace factory components in 5.0L TiVCT Coyote engine oil pump housings. These gears are engineered for extreme durability, featuring a design capable of withstanding output exceeding 3,000 HP and engine speeds beyond 10,000 RPM. This makes them suitable for both high-output daily drivers and competitive, high-horsepower racing builds. Installation is designed to be a direct fit into existing 5.0 TiVCT oil pump housings without modification. Note that for 2018+ F150 applications, installation requires swapping to a 2015 Mustang oil pump housing. This product is intended for closed-course competition use only and is not intended for street use. Users should be aware that the sale, use, or installation of this product may be considered illegal under the Federal Clean Air Act. These gears are compatible with 2011-2026 Mustang GT, 2016-2020 GT350, and 2011-2017 F150 5.0L models. They are not compatible with GT500 models, which require a different part number (400224B). Each set includes a lifetime warranty for the original owner.
