Kibblewhite Lower Collars

Kibblewhite makes these lower collars to keep your valve springs perfectly in place. The lower collar provides a seat for the valve spring to keep it from moving around, causing excessive wear to your engine or the spring itself. These collars are machined to the highest standards out of either 7075-T6 aluminum or precisely controlled, heat-treated steel, depending on the application, to provide the best results. Don't miss out on a small item that can have a big impact--upgrade to these Kibblewhite lower collars when you are upgrading the rest of your valvetrain.
