Stud Mount Rocker Arm Conversion - 3/8" - 5.0/5.8
With this conversion kit, you can quickly change the 5/16 pedestal mount rocker arms on your 1979–1993 Fox Body Mustang 5.0 or 5.8 to a stronger 3/8 stud mount. Upgrading to a 3/8 stud mount rocker arm adds stability to your valvetrain and opens up more rocker arm choices. You can transform your heads to an adjustable-type valvetrain using this stud mount rocker arm conversion without the need for machining or removing the cylinder heads. Each of these kits includes guide plates, guide plate inserts, studs, and guide plate channels. These kits are great for mild-performance engine builds using hydraulic lifters or hydraulic roller camshafts.
