Camshafts & Valvetrain - LF3/LF4 82# Valve Springs

This is a full set of 24 titanium retainers and 82# valve springs for your LF3 or LF4 that comes in the 3.6 twin turbo which is in the ATS-V, CTS/XTS V-Sport. The factory valve springs float at around 6000rpm when you turn the boost up in those engines. These valve springs will add roughly 1000 more RPMs to your power band. It is hard on valve springs when they float (they can break and drop a valve into the cylinder), so these valve springs will not only improve performance, but also the reliability of your car.

Great customer service

If you are going to increase your your boost and or RPMs these springs are a must have. Easy install as far as spring replacement goes. The quality of these parts makes it an easy job for someone that’s done it before but get some help from someone experienced if you are new to spring replacement. Scott is very knowledgeable on these cars and his customer service is impeccable.
