Peterbilt qudraflex spring suspension usefulness
i just purchased a 2001 Peterbilt with a quadraflex spring suspension. I plan to go over the truck and make the necessary repairs or upgrades prior to putting it into service. i plan on pulling a liquid asphalt tanker and a dump trailer . All of my other Peterbilts have air ride suspensions. Are their any advantages to the spring suspension? Can I or should I consider upgrading or changing to air suspension?
Is this a good question?
