CHROME-MOLY VALVE SPRING RETAINERS
These retainers are machined from aircraft-quality, chrome-moly, alloy-steel that far exceeds the industry standards for steel retainers. All retainers are heat-treated to 46-50 Rockwell- C, then tumbled and finished with black-oxide to prevent rust. PBM Chrome-Moly Retainers, deliver incredible strength, with just slightly more weight than more expensive titanium retainers. Chrome-moly retainers are designed for Street, Off-Road and all but the most severe racing applications. They are ideal for Oval-Track racing.
