Liteflex Epoxy Springs Leave 
Urethane Springs in the Dust. Literally!

DAYTON, OHIO – Liteflex springs enjoy the highest temperature resistance of any known composite leaf spring. Thanks to vastly superior epoxy resin and several unique manufacturing processes, Liteflex springs have a Tg of 165°C (325°F). That’s compared to an approximate Tg of 130°C (265°F) for urethane and other inferior materials.

Plus, Liteflex is the only manufacturer to post-cure their springs, which optimizes performance and frankly, further highlights urethane’s vulnerabilities.

In fact, a Liteflex customer recently conducted desert testing with competitor springs and experienced catastrophic failure. Their urethane springs broke into two pieces and rendered the vehicle inoperable. Aware of the higher temperature resistance for Liteflex springs, the customer installed Liteflex replacement parts and was able to complete their testing.

“The desert failure clearly demonstrates the heat limitations of urethane springs,” says John Prikkel, President of Liteflex. “Thankfully, it occurred under controlled circumstances and without harm to occupants or property.”

This ability to endure extreme temperatures provides confidence for operators in hot regions of the world and also gives engineers more flexibility when designing near engines and exhaust systems. Besides performing at the highest temperature and humidity conditions, Liteflex springs have also performed in cold climates as low as -60°C (-76°F) and are impervious to road salts and deicers.

Providing the same ride, at the same reduce weight (compared to steel), Liteflex’s epoxy springs are stronger and more durable. They have been in continuous serial production since 1981.
