Tired of wrestling with rocker arms? I get it. It can be a real pain, but Ford Racing has come to the rescue with these rocker arm shim kits. Designed for those bolt-down style roller rocker arms, these kits help you nail down the right lifter preload without the hassle. You get 16 thin shims and 16 thick shims in the kit, letting you tweak lifter preload by .030 in. with the thin shims, .060 in. with the thick ones, or even .090 in. if you combine both. It's pretty straightforward, and it makes a world of difference in your engine's performance.
This kit is specifically made for 4.6L 3V cylinder heads, so if you're working on that setup, you're in luck. You'll get a total of 24 shims, which means you can really dial in your rocker arm adjustment. No more guesswork—just solid, reliable performance.
Universal Fitment: While these shims are designed for a range of applications, it's always a good idea to double-check compatibility with your specific setup. A little research can save you a lot of headaches down the line.
