Question:

How many bolts do you have to use to mount to trailer on a rotoflex 18k, it has 3 in the front row and 2 in the back row for each side. Can I the pin box one hole and mount with 2 in the front and 2 in the back on each side.

Expert Reply:

When you attach a RotoFlex pin box like the part # LC328330 you will need to use the same amount of bolts per side of the pin box like that the original pin box used to secure to the trailer frame.

Some setups will require only 4 bolts and some may require 5 or 6. It really depends on the trailer and what was originally on the trailer.

Can I lower the Lippert Rota Flex pin box by one bolt space to cause nose to be higher?

The Lippert Rota Flex pin box can indeed be lowered on your existing flange brackets just like your existing pin box could, assuming it's not already on its lowest setting. This is a simple way to to create a level ride when hooked up to your truck.
