GSC Power-Division STD 32mm Super Alloy Exhaust Valve Coyote Gen 3 Set of 8

Vehicle Fitment

• Ford Mustang 5.0L Coyote Gen 3 (2018+)
• Ford F-150 5.0L Coyote Gen 3

Fitment Notes

• Features a 45° valve seat contact angle, differing from the OEM 40° design - a valve job is required for proper sealing and valvetrain geometry

Features

• Super Alloy construction for high-strength, high-temperature durability
• Advanced 3D design and flow simulation for a stronger, higher-flowing valve head
• Hardened or stellite wafer-tipped for extended life and minimal wear
• Balanced keeper groove designed to work with OEM keeper/lock systems
• Flow-tested prototypes to maximize head flow for the application

Product Description

The GSC Power-Division 2165-8 is a set of 8 standard-size (32mm) Super Alloy exhaust valves built for the Ford 5.0L Coyote Gen 3 engine in the Mustang and F-150. Using advanced 3D design and flow simulation, GSC engineered a stronger, higher-flowing valve head compared to stock, with each design flow-tested to confirm real-world performance gains.

The valves feature a 45° seat contact angle rather than the factory 40° design, so a valve job is required during installation for proper sealing and valvetrain geometry - this isn't a drop-in replacement without machine work. The balanced keeper groove is compatible with OEM keeper/lock hardware, though GSC recommends against reusing old locks on a performance build due to potential grooving.
