TOYOTA BEAMS 3SGE. Performance Beehive spring and Titanium retainer kit. This kit has been designed to convert to the more commonly available 10mm diameter valve shim. This allows easy sourcing of shim sizes to suit modified engines, and a slight reduction in valvetrain mass. This kit will allow for re-shimming of engines using OEM cams with OEM lobe base circle diameter, or cams which have been re-profiled and on a smaller base circle diameter. Currently do not offer brand new racing cams for the BEAMS 3SGE but we can regrind your OEM cams to suit NA racing or turbo applications. This will result in a reduced lobe base circle diameter. Spring data: 100lb seat pressure at 39.2mm installed height. 185lb at 11.0mm valve lift. Spring coil bind height 25.4mm.
