I am changing my pin box from a Roto Flex to a MORRyde Pin Box. The 12 attachment bolts / nuts where snug at best. The bolts are supposed to be torqued to a minimum of 130 FT LBS. We have a 2020 Montana HC 331RL with aprox 600 miles on it.
The torque on those bolts and nuts depend on the bolts used, as heavier bolts, both by size and grade will require more torque. The chart in the installation instructions provided by MORryde will give you the proper torque for those fasteners. http://www.morryde.com/uploads/downl...structions.pdf
