Features & Product Details

RallySport Direct carries a great selection of quality performance valvetrain upgrades brought to you by GSC Power-Division. 

Here, you are looking at the GSC Power-Division 32mm Stainless Steel Exhaust Valve Set. These exhaust valves have been designed using advanced 3D design simulation programs to create a stronger and higher flowing valve head.
 

 

DETAILS:

  • 32mm in size
  • Swirl polished heads for smoother air flow over the valve
  • Back cut to reduce valve weight for higher rpm, higher boost pressure, and allow for more aggressive cam profiles without increasing valve spring seat pressures
  • Valve stems are micro-polished to allow for less oil retention on the stem which creates less drag on the stem to guide for a smoother motion
  • Fully nitrated ( this includes the 45 which increases valve life and makes a better seal at the valve seat for improved cylinder pressure) also reduces carbon buildup on the backside of the valve
  • Intake valves are a modified 21-4n stainless and Exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity
  • Valve tips are either hardened or have a stellite wafer tip fused so that the tip is within 5 Rockwell C of the rocker or valve tappet for extended life and less wear
  • Valve tip lengths. They have taken extra time to adjust tip heights on the applications to require less tipping of the valve to maintain proper tip height for proper valvetrain geometry and to cut down on install times when setting valve lash
  • They have also adjusted the Keeper grove to properly balance intake and exhaust spring pressures to reduce the use of valve spring shims and maximize performance from their spring and retainer kits
  • Valves will work with an OEM keeper/lock or when available their upgraded keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance applications due to material grooving
  • Includes (8) exhaust valves

    5out of 5stars
    MikeA
    I'm down 12,000miles with is valves and still holding .. first impression made with very high quality standard .. down side like other reviews depending on your valve seat they can be longer than oem valve even with the smallest valve shims they are still longer ..you will have to grained down to size the valve steam . because of this i'll give it 2 stars for installation .. but over all I love this valve.

    QUESTIONS & ANSWERS

    • Q: Valve length  mitchssubie2 years ago

      Are these valves 104.78mm or 106.12mm long?
    • Q: Machining?  RS25SUBIE3 years ago

      Does these valves require any machining to be done or just a straight valve swap?
      • 0 of 0 people found the following answer helpful

        A:  I would lap the valves at a minimum to ensure a proper seal, but you builder or machine shop may do some light machining on the seat to get the best flow and seal. Hope this helps!

    • Q: contents  MrRyan5 years ago

      Do these valves come with the keepers or valve locks?
      • 0 of 0 people found the following answer helpful

        A:  These do not come with either. you would want to buy valve keepers/valve locks separate.
