Just a standard lippert spring assist. 3 springs on the hinge on the bottom of door. Nothing to adjust really,thats why I asked if it would make a difference if I put a 1/2 or 3/4 inch block under end of spring to give it a little umph .door isn't really HEAVY as much as it isn't BALANCED. its just not as pre loaded as I would like.
