Description
 

Now featuring, dual high-lift valve springs from PSI (Performance Springs Inc.). PSI is a leading manufacturer of high performance valve springs since 1996.

Every PSI spring begins with wire that is made from the highest quality Chrome-Silicon alloys. The 1200 Series builds on this by employing advanced heat-treating operations. These heat treatments increase the strength of the base materials. This increase in strength results in improvement to the fatigue limit of the wire and better resistance to load loss. These factors together allow the engine builder to push the valve train set-up to the next level!

As an upgrade option, PSI offers their springs with Max Life Surface Preparation (ML), a proprietary, multi-step surface enhancement process that has been proven to increase spring endurance. Max Life processing is very beneficial for those looking for increased endurance while maintaining their existing set-up.

For those looking to upgrade an existing set of heads, the CT-1225/CT-1225ML are direct replacements for the K-800 springs. They use the same retainers and have the same spring pocket O.D.

Sold in sets of 8. Also available, the CT-1225 with standard finish.

CT-1225 Springs are available as a performance option when you purchase a set of Competition Eliminator Cylinder Heads. The use of our 10 degree Valve Spring Retainers is recommended.
