PAC Racing 600 Series Valve Spring Retainers

PAC Racing 600 Series valve spring retainers are the latest developments from PAC Racing Springs. These retainers feature ultra-lightweight designs from proprietary valve spring-type alloys. PAC Racing's sophisticated processing, such as micro-polishing and Nano Peen technology, are used to enhance retainer life. The high hardness of the steel provides higher wear resistance properties to offer superior abrasion resistance and improved fatigue strength, while also reducing weight. PAC Racing 600 Series valve spring come with a reduced step and need to be combined with a matching seat (where applicable) to optimize the performance of the valvetrain.
