Valve Springs

Your stock valve springs are only rated for stock RPM. The second you start pushing a hotter cam, more lift, or higher redline, weak springs let the valves bounce and float instead of snapping shut when they should — and that costs you power, or worse, a bent valve.

That’s what valve springs are built to fix. A good spring keeps the valve seated tight and controls it through the entire lift cycle, even when you’re spinning past the limits your factory setup was designed for. Whether you’re running a mild cam upgrade or building toward a full high-performance setup, matching your springs to your cam profile is one of those details that separates a reliable engine from one that grenades at 8,000 RPM.

Look for springs with the right spring rate and installed height for your specific cam and cylinder head combo — running the wrong spring can do more harm than running the stock one. If you’re not sure what you need, check your cam card or reach out before you order; getting this part right up front saves you a lot of headaches (and money) down the road.
