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.

Expected motor life has increased greatly through the years, but anything with moving parts is susceptible to wear and will eventually need rebuilt. PAC Racing 300 Series valve spring retainers are made from 4140 aerospace grade chromoly steel, making them an excellent choice for stock to slightly modified rebuilds. PAC does their own in-house manufacturing, allowing them to build strength into these units. They are heat-treated for solid wear characteristics and to raise the tensile strength, and for a rust-free finish, they apply black oxide coatings. Into every engine a little work must go; make certain you use the right parts for your stock to slightly modified build with PAC Racing 300 Series valve spring retainers.

PAC Racing Beehive Series valve springs combine the latest technologies available to produce the best performing springs on the market. Reducing the top coil of the springs allows for a reduced mass retainer. Additionally, beehive springs offer a multi-arc (ovate or egg-shaped) that allows for the stress distribution of the wire to be equally distributed on the opposing sides of the wire. Combine these features--and the result is a variable-frequency spring that performs at a higher level rpm than traditional springs.
