Dual Spring & Titanium 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"!

Titanium Retainers

LC Engineering offers CNC machined retainers made from high strength, heat-treated titanium alloy. Designed to add strength while offering weight reduction. Perfect for high RPM, street, and race applications. It should be used with our hardened keepers and spring kits.

NOTE: LC Engineering also offers this kit with Chromoly retainers, see Part #: 1023211.
