LS engine builders, listen up - these Dokili LS6+ valve springs are serious upgrades for your build! This set of 16 springs is specifically designed for LS engines running mild cam swaps, delivering increased valve train stability with a much lighter setup. The engineering here is impressive - they provide 4% higher seat pressure and .030\ higher valve lift capacity compared to standard blue LS6 springs, which means better valve control and reliability at higher RPMs. With a 386 lb/in spring rate, 1.181\ coil bind height, and 1.282\ outer diameter, these are built for performance. The reduced weight of both the spring and retainer means less stress on your valve train components, which translates to more durability and potentially higher RPM capability. The quality is clearly there in the small-batch manufacturing and premium materials used. These springs handle up to .580\ max lift, making them perfect for those mild to moderate cam upgrades where you need more performance without going to extreme race-level springs. The higher spring rate compared to stock LS6 springs means better control and stability, especially important when you're pushing your engine harder. Installation is straightforward for anyone familiar with LS valve train work, and the results are definitely worth it. Whether you're building a street performance engine, a track day car, or just want the peace of mind that comes with upgraded valve train components, these springs deliver the performance and reliability that LS enthusiasts demand. The attention to detail in the manufacturing process ensures consistent quality across all 16 springs, which is crucial for balanced engine performance.
