Steel Intake Valve / Spring Kit

Latest addition to the ProX program is the Steel Intake and Exhaust Valve & Spring Kits. This kit is offered as an alternative where the OEM application uses Titanium valves. ProX has now developed the Steel Intake and Exhaust Valve & Spring Kits, containing a set of steel intake or exhaust valves plus a set of specially designed stronger valve springs. The ProX kit just replaces the OEM valves & valve springs and can be installed using the OEM retainers, bases and valve seals.

  • Steel Valves for increased durability and less wear under extreme conditions
  • 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 at high RPMs
  • Fully rebuildable with OEM retainers, bases and seals without the need of any further engine modifications
  • Comes as complete package for quick, easy and cost efficient replacement
Note: Please make sure repair parts fit your vehicle before purchasing. Check our parts diagrams, catalogs or contact us.
