Springs for logging vehicles can weigh as much as an entire car. These coiling technologies require extension springs and the U bolt to be designed with utmost care. Very few companies have the ability or expertise to manufacture suspension springs that may carry loads in excess of 100,000 lbs. We are one of the few, and we have a long and proud history of over 100 years, of supplying to this vital industry.
