Installing a new camshaft is a sure way to improve horsepower--just remember that the rest of the valvetrain must be upgraded for proper operation. Speedmaster valve spring and retainer kits include everything you need to keep your engine running in top shape after a cam swap. They offer you an easy, cost-saving method of ensuring that your cam is matched with the correct components. The springs will help engines by releasing some of the horsepower that the stock components are holding back.
