Hey Keith, thanks for reaching out! For the etrailer Slipper Leaf Spring # e49SR, I recommend positioning the rear hanger so approximately 2" of the slipper end extends past the hanger's contact point when the trailer is unloaded. This is a general starting point rather than an exact manufacturer specification, but it helps keep the spring supported while allowing it to slide as the suspension moves. You'll also want to make sure the spring has enough room to travel without slipping out of the hanger or bottoming out as the suspension compresses and extends.

Are you replacing the springs on an existing trailer or building a new suspension setup from scratch?

Thank you for the information. Replacing worn out slipper springs and and these were the best fit springs, but required a new rear hanger to be welded as the older slipper springs were longer.

@KeithS ok gotcha. Yes 2" from the tip of the slipper end is a great starting point. Its always a good idea to mock everything up and just make absolutely sure it all lines up on your end.
