Pro Dual Valve Spring & Retainer Kit

LC Engineering has taken the guesswork out of choosing the right parts for your cylinder head! We have created a spring & retainer kit that comes with all the parts needed to upgrade your 2TR cylinder head to a dual spring set-up.

Pro Dual Valve Springs

The Pro Dual Valve Springs are a "must-have" upgrade when running bigger lift cams and higher RPM's. With 65lbs of seat pressure at a 1.430" install height, they will work perfectly with any naturally aspirated or low boost application (0-20 lbs of boost).


  • Type: Dual Spring
  • Press.Seat: 65 @ 36.19mm (1.430")
  • Open Press.Seat: 185 @ 10.16mm (.400")
  • Max Lift: 13.80mm (.540")
  • Coil Bind: 21.80mm (.858")
  • Rate: 13.50 lbs/mm

Spring Seats

Our spring seats are custom designed to allow you to run our dual springs without having to machine the cylinder head or guides (like some of our competitor's kits require). You place this spring seat on top of your stock spring seat, and you are ready to go.

Titanium Retainers

These lightweight retainers allow the valves to open and close faster and more consistent by reducing the drag and load on the springs. The titanium also provides superior strength and durability which means your engine can rev faster and higher than ever with no reliability worries.
