Boundary 99-05 Ford Modular Motor 4V V8 Billet Crankshaft Timing Sprocket w/Adjustable Keyway

This is the Boundary billet crankshaft timing sprocket specifically for 1999-2005 Ford Modular 4V V8 engines. It's designed to give you precise control over your engine's timing, which is crucial for performance and smooth operation. If you're rebuilding the top end or looking to fine-tune your engine's camshaft timing, this adjustable keyway sprocket is a solid choice.

What sets this sprocket apart is its billet construction and adjustable keyway. Instead of a fixed keyway, this sprocket uses an adjustable system that lets you dial in the camshaft timing with greater accuracy. This is especially helpful when you've made other modifications to the engine, like changing camshafts or cylinder heads, and need to optimize valve events. The billet material means it's well-built and strong, able to withstand the demands of a performance engine.

When installing, you'll want to pay close attention to the manufacturer's instructions for setting the adjustable keyway. Getting the timing just right can make a noticeable difference in how your engine runs, from idle quality to power delivery at higher RPMs.
