Ford Racing 2020 5.2L Predator Roller Finger Follower Kit

Upgrade the Entire Valvetrain on Your Gen 3 Coyote or GT350 with 32 GT500 Roller Finger Followers in One Kit

The Ford Performance M-6564-M52A is a complete set of 32 camshaft roller finger followers sourced directly from the 2020 Shelby GT500 and engineered for use in the Gen 3 5.0L Coyote, 5.2L GT350 Voodoo, and 5.2L GT500 Predator cylinder heads. Roller finger followers are the interface between the camshaft lobe and the valve stem, and the GT500 versions in the M-6564-M52A feature higher-strength steel rollers and upgraded bearings compared to the production Gen 2 followers, making them a common upgrade for performance builds targeting higher RPM use, aftermarket camshafts, or simply a factory-spec refresh with GT500-grade hardware. The kit covers both intake and exhaust positions on all four cam positions, providing a complete valvetrain renewal in a single part number. Designed as a direct OEM fitment replacement for the Gen 3 Coyote platform with no modifications required.

Frequently Asked Questions

The Ford Performance M-6564-M52A is a complete set of 32 camshaft roller finger followers taken directly from the 2020 Shelby GT500 production spec. It is designed to fit the Gen 3 5.0L Coyote, 5.2L GT350 Voodoo, and 5.2L GT500 Predator cylinder heads, providing upgraded higher-strength roller and bearing assemblies for engine builds, valvetrain refreshes, or direct-replacement service on compatible applications.

The M-6564-M52A fits the 2015-2020 Mustang Shelby GT350 and GT350R, the 2018-2024 Mustang GT and GT Premium, the 2020 Mustang Shelby GT500, the 2019-2020 Mustang Bullitt, the 2021-2023 Mustang Mach 1, the 2024 Mustang Dark Horse, and 2018-2020 Ford F-150 trucks equipped with the 5.0L Coyote engine. It is not compatible with Gen 1 (2011-2014) or Gen 2 (2015-2017) Coyote cylinder heads without confirming head casting compatibility.

The kit includes 32 roller finger followers, which is the complete engine set for a two-cam-per-head, four-overhead-cam 5.0L or 5.2L Ford V8. This covers all intake and exhaust positions on both the driver and passenger side cylinder heads in a single purchase.

The GT500 followers use higher-strength steel rollers and upgraded needle bearings compared to the standard Gen 2 Coyote production parts. For performance builds targeting higher RPM, aggressive aftermarket camshafts, or boosted applications, the stronger GT500 spec followers provide greater durability and reduced wear under sustained high-load operation. They are also the correct OEM replacement for Gen 3 Coyote and GT350 service.

Lash adjusters are compatible across Coyote generations and do not require replacement when installing the M-6564-M52A. However, on high-mileage engines or during a full valvetrain refresh, replacing the lash adjusters at the same time is common practice to ensure consistent valvetrain geometry across all positions. Ford Performance part M-6564-M52LA or equivalent covers the lash adjuster set if needed.

Yes. The M-6564-M52A GT500 followers are compatible with most aftermarket camshaft profiles designed for the Gen 3 Coyote and 5.2L GT350 platforms. However, extremely aggressive lobe profiles with steep ramp rates or high lift numbers may require cam-specific follower validation from the camshaft manufacturer. For Coyote performance builds, these are the preferred OEM-sourced follower for most reputable cam grinder recommendations.

The M-6564-M52A is designed for Gen 3 Coyote heads and 5.2L Voodoo heads. The Gen 2 Coyote uses a different rocker arm geometry and rocker ratio (1.73:1 versus the Gen 3's 2.04:1), so the M-6564-M52A is not the correct replacement for a Gen 2 application. For Gen 2 Coyote service, use the M-6564-M50 instead. Confirm cylinder head casting before ordering.

The rocker ratio varies by application. In the 5.2L GT350 Voodoo heads, the followers operate at a 1.9:1 ratio. In the Gen 3 5.0L Coyote heads, the ratio is 2.04:1. The M-6564-M52A follower geometry is optimized for these head configurations and provides a slight increase in effective valve lift over the equivalent Gen 2 Coyote follower when installed in Gen 3 heads.

Installation Instructions

1. Remove the valve covers on both cylinder heads and ensure all camshaft position sensor wiring and accessory routing is cleared before accessing the camshafts.
2. Rotate the engine to TDC on the cylinder you are servicing and confirm no valves are in contact with the follower positions you are removing. Never remove followers under spring load.
3. Using a valve spring compressor tool designed for the Coyote platform, depress the valve spring to unload each follower, then extract the follower from the rocker arm tray using a magnet or follower removal tool.
4. Clean the rocker arm tray, lash adjuster bores, and camshaft bearing surfaces of any debris or oil deposits before installing the new M-6564-M52A followers.
5. Pre-lubricate each new follower roller and the cam contact surface with clean engine oil before installation.
6. Insert each follower into its bore, confirming it seats fully and the roller is correctly oriented to contact the camshaft lobe.
7. Release the valve spring compressor slowly and confirm the follower is seated without binding.
8. Repeat for all 32 positions across both cylinder heads.
9. Reinstall both valve covers with new gaskets. Torque to factory spec (89 in-lb).
10. Refill engine oil if any was lost, start the engine, and inspect for oil leaks at the valve covers before returning to service.
