Description
This valve spring kit is a high quality set of springs that comes with a light weight 7000 series billet aluminum spring retainer and a set of shims to allow the engine to rev to around 5500rpm. The max RPM will obviously depend on your camshaft profile but for lower RPM, non-aggressive lobe profiles they will be just fine. Kit is designed to use the OEM valve keepers and are a drop in kit with no machine work required.
