Supertech now offers a performance dual & single valve spring and retainer kits for the Mitsubishi 4G63 EVO engine.

Supertech Single/Dual Valve Springs:
Supertech performance valve springs are made with premium Superclean Chrome Silicon Vanadium Steel Alloy for higher performance and durability. Computer designed to ensure that wire stress levels do not overpass the limits for long durability under extreme conditions and harmonics are well under control.

Supertech Titanium Retainers
Supertech titanium retainers prevent valve float and strength up your valvetrain. Retainers are CNC machined from 6AL4V grade titanium.

Supertech Spring Seat Locater
Supertech spring seats are made from high grade steel and aide in the upgrading to dual valve springs. Thickness of spring seats may vary.

Supertech Viton Valve Seals
Supertech Viton valve stem seals are reduced outer diameter valve seals, perfect for those that are using dual valve springs that may otherwise have valve spring clearance issues. Also a performance option for those that just need to install new valve stem seals due to worn existing seals.

      Nice Looking Watch
      Received this watch for my son-in-law for Christmas. He is a "watch" person. The only complaint I have is that it was sent already running which makes me think the battery will expire sooner than later. The watch is very nice looking.
