Triangle craftsmen put their steel through a rigorous battery of tests before being satisfied that the steel is top quality and suitable to be made into a spring for your vehicle. They use advanced technology to make your spring better able to resist the punishment of highway and off road conditions for a longer period of time. Triangle manufacturers pride themselves on being able make just about any kind of hard-to-find or out-of-date spring, going all the way back to 1919, when the company got started. And if that isn't impressive, consider that they can often get those parts out of the plant door in only 24 hours.
