Dual Spring & Chromoly 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 20R/22R/RE/RET 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 100lbs of seat pressure and open pressure of 210lbs (at .500" lift) they will work perfectly with any naturally aspirated or boosted applications. These springs are rated up to 8,500 RPM and will accommodate cam lifts up to .550"!

Chromoly Retainers

These Chromoly retainers are necessary when running dual springs. The unique design of these retainers will preload the inner spring to make sure you get the correct spring pressure and location. Chromoly retainers are not as light as our titanium versions, but they are slightly less expensive for those of you on a tighter budget.

NOTE: LC Engineering also offers this kit with Titanium retainers. Check out Part #: 1023210.
