Product Description

The Ford Racing M-6500-R302H High Performance Hydraulic Roller Lifters are engineered to elevate the performance of Ford small block V8 engines equipped with roller camshafts. Developed by Ford Performance for competition and high-RPM applications, these lifters feature a ceramic check ball and higher rate piddle valve spring to keep stable oil pressure under extreme conditions, extending usable RPM range by approximately 200-400 rpm versus stock lifters.

Sold as a complete set of 16, the M-6500-R302H lifters are a direct replacement for the original hydraulic roller lifters in compatible engines, including 5.0L and 5.8L Mustang applications from 1985 through 1995. They use standard dog-bone tie bars and retainer plate hardware, making them ideal for both performance rebuilds and racing-focused builds when maximizing valvetrain stability and RPM capability is a priority. Installation requires cylinder head removal, and proper valvetrain setup is critical for best results.
