With over 20 years of experience designing, manufacturing and testing titanium springs for demanding aerospace applications; RCS has expanded their expertise to new markets where performance counts. Due to their higher frequency response and improved suspension dynamics, titanium springs have more resistance to set and a longer fatigue life than the highly stressed steel springs that are common in performance applications.

Titanium springs are lighter, have a higher frequency response and improved suspension dynamics. Properly designed, titanium springs have more resistance to set and longer fatigue life than the highly-stressed steel springs common in performance applications.

In the late 1990’s, RCS started exploring new materials, and discovered UPG-TEN. It is a very ductile material known for its extremely high tensile strength, magnetic properties, and heat resistant properties. These attributes have made it a perfect fit for stock car applications and has worked well in conjunction with the wide range of rates used. It has been proven that even when coil-binding, it does not take set and offers more travel, even with lighter spring rates.

RCS engineers design springs specifically for demanding applications, not around the production ease or common material sizes as with most mass-produced steel springs. This results in a custom designed spring that is as light as possible while providing the strength and durability demanded by the application. RCS offers complete engineering assistance to help our customers. Advanced materials, computer modeling, and extensive experience are the foundations of a successful spring design.
