Manley Valve Spring, SPRING-1443 POLISHED

If you're rebuilding the top end of your engine, you'll need a solid set of valve springs. This set from Manley Performance, part number 221443P-16, is designed to handle the demands of high-performance applications. They are a popular choice for builders looking for reliable components that can withstand increased lift and duration from aggressive camshafts.

Manley has polished these springs, which is a notable step beyond standard manufacturing. This polishing process helps to remove surface imperfections that could become stress risers, leading to improved fatigue life and a more durable spring. This attention to detail means these springs are well-built to perform consistently under pressure, whether you're on the street or the track. They are designed to work with many popular aftermarket camshafts, but it's always a good idea to check the specific lift and seat pressure requirements for your build to ensure compatibility.

This set includes 16 individual valve springs, enough for a typical V8 engine. When installing, remember to follow the manufacturer's recommended installation procedures and torque specifications to ensure proper function and longevity. Proper installation is key to getting the most out of these well-made components.
