The Speedmaster PCE308.1017 is a precision 3.900" LS piston oil ring rail spacer support designed for LS-series engine rebuilds and performance upgrades. This 0.040" thick spacer support maintains proper oil ring rail clearance and positioning within the piston ring groove, a critical function for controlling oil consumption and ensuring correct piston ring operation during engine operation.
Manufactured to OEM specifications, this spacer support is an essential component for high-quality LS engine assembly. It provides precise spacing between the oil ring rail and the piston wall, preventing ring flutter and excessive oil bypass. Whether you're performing a complete engine rebuild, replacing worn pistons, or assembling a performance LS engine, this spacer support ensures the oil ring functions as designed for proper lubrication management and ring longevity.
