Product Details

ProX 28.SIS4406-2 Valve and Spring Kit

Valve and Spring Kit

  • An alternative where the O.E.M. application uses expensive and less durable titanium valves
  • These steel valves offer increased durability and easily extends the lifespan to 3 times that of the O.E.M. titanium valves
  • Nitrided valves offer high microhardness while supersmooth surface finish reduces friction between stem and guide
  • Special stronger valve springs deal with the extra weight of the steel valves
  • Springs are made from premium chrome vanadium steel for higher performance and durability under high RPM
  • Fully rebuildable with O.E.M. retainers, bases and seals without the need of any further engine modifications
  • Intake and exhaust kits complete packages for quick, easy and cost efficient replacement
