M416 Spring Replacement
I use my M416 exclusively as an off road adventure trailer. I have found the original springs to be a little stiff. To rectify this I ordered 8-leaf springs from JC Whitney and performed a quick swap.

The springs are for the front of a CJ3 jeep. I also replace the shackle bolts at the same time.

I used my tongue jack to lift the trailer wheels off the ground. The spring replacement took about 30 minutes per side.
I keep thinking about doing this! You are once again setting the pace!
Thanks
