The Manley upgraded beehive valve spring and titanium retainer set is a great choice for Subaru EJ20 / EJ25 engines with upgraded camshafts that require valve springs for increased lift and higher RPM use. The set combines Manley's upgraded 310 lbs./in valve spring set (Part# 22185-16) with their matching titanium retainers (Part# 23185-16). The retainers are manufactured from heat treated aerospace grade titanium, then CNC machined to exacting tolerances for an excellent fit.Valve Spring Specs:Type: Single Conical Ovate WireOuter Diameter: 1.126"Inner Diameter: .40"Pressures: 95 @ 1.420" / 217 @ 1.050" / 264 @.910"Stock Net Lift: .370"Maximum Net Lift: .510"Coil Bind: .860"Rate lbs./in: 330Quantity: 16Retainer Specs:Weight: 5 GramsValve Stem Diameter: 6.0mmValve Lock Degree: 6 DegreesDimensions: A= .875" / B=.627" / C= .465" / Step= .095"
