Ford Racing M-6529-3V Modular 3V Rocker Arm Lash Adjuster Kit x24 for 4.6L SOHC

Vehicle Fitment

• 2005-2010 Ford Mustang GT (S197, 4.6L 3V SOHC V8)
• 2008-2009 Ford Mustang Bullitt (S197, 4.6L 3V SOHC V8)

Fitment Notes

• Fits all 4.6L 3-valve (3V) SOHC cylinder heads - engine sets only; one kit covers one complete engine
• This is the original production rocker arm used on 2005-2010 Mustang GT from the factory
• Does not fit 4.6L 2V (2-valve) or 4.6L 4V (DOHC) cylinder heads
• Does not fit 5.4L 3V engines (F-150, Expedition) - rocker arm geometry differs
• Sold as a complete engine set of 24 rocker arms and 24 lash adjusters
• Recommended when replacing camshafts or performing a full valvetrain refresh

Features

• Extruded aluminum rocker arm bodies are lighter and stiffer than OE cast rocker arms for improved valvetrain response
• Needle-bearing fulcrum reduces friction at the pivot point for lower valvetrain losses and reduced heat
• Roller tip contact reduces side load on the valve stem and valve guides, extending guide longevity
• OE production part - direct fitment with no machining or modification required
• Shaft-mount design provides more consistent rocker geometry compared to stud-mount alternatives
• Engineered and manufactured to Ford Performance's factory quality standards

Product Description

The Ford Racing M-6529-3V is a complete engine set of 24 roller rocker arms and 24 lash adjusters engineered specifically for the 4.6L 3-valve SOHC Modular V8. This is the same rocker arm used as original production equipment on the 2005-2010 Mustang GT, making it an ideal choice for cam swaps, high-mileage refreshes, or full engine builds requiring confirmed factory-spec geometry and fitment. The extruded aluminum bodies deliver a lighter, stiffer rocker than the stock castings, while the needle-bearing fulcrum and roller tip work together to reduce valvetrain friction and extend the service life of both the valve guides and the cam lobes.

Installing a full set of fresh rocker arms and lash adjusters during a camshaft replacement is strongly recommended, as worn lash adjusters can produce inconsistent preload and valvetrain noise even with new cams installed. The M-6529-3V kit eliminates that variable entirely with one complete, factory-backed solution. Compatible with the 2005-2010 Mustang GT and Bullitt; not compatible with 2V, DOHC 4V, or 5.4L 3V cylinder heads.
