Testimonials

Hi Heather,
While things do not always go according to plan sometimes,
it has been very re-assuring that you have taken the time to ensure your customer was totally satisfied, there was late
delivery on my end with my freight forwarder but also there was a trust between lancershop & the customer (myself) n this case.
Lancershop could have easily said that the issue is outside the company policy of 30 days after purchase was made.
However you still took the time to investigate my claim & the honesty level of accepting that i have received half the
items purchased. This situation does represent a high sense of integrity in what you do & i applaud you & Lancershop
for demonstrating such. Thank you for the excellent customer service even with the previous carbon parts coming from
china/japan............ i do look forward to doing business with you again in the future.

GSC Chrome Polished Super Alloy Exhaust Valve Set of 8 - 31.5mm Head(+1mm) - EVO 8/9

Product Description

When creating our new valve line we set out to create the best performance longest lasting valves available to the aftermarket. Using advanced 3D design and simulation programs we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available on the market today. With the materials used we have less valve distortion at the face than any of the tested designs. Less distortion allows or better sealing under extreme conditions and more consistent performance threw the life of the valve. GSC Power-Division's new valves are sure to become the industries standard for sport compact performance valves.

Valve Features

    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 micropolished to allow for less oil retention on the stem which creates less drag on the stem to guide for a smoother motion.

    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 stelite 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. We 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 valve train geometry, and to cut down on install times when setting valve lash.

    We 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 our spring and retainer kits.

    Valves will work with an oem keeper/lock or when available our upgrade keeper/lock. It's not mandatory but it is suggested that any valve lock not be reused on performance applications do to material grooving.

Fits: Lancer EVO 8/9
