Good To Know
Q: How often should the No Slack springs be replaced? A: The springs in a No Slack mechanism typically wear over time and should be inspected annually. Replacement is recommended when coupling slack becomes noticeable or during major fifth wheel service.
Q: Will this kit fit older Fontaine models besides the NT series? A: This kit is specifically designed for NT 6000, 7000, and 7000CC models. For other Fontaine fifth wheel models, confirm spring dimensions and part numbers directly.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
