That's what im saying mate, the actuator although its a brand new forge item is weak as anything, over a 1/3rd weaker than the previous one so even with a mass of pre load its just opening it so easy. Im going to measure the original one tomorrow and see what reading I get then get onto forge for another spring. Im pretty sure the previous actuator was the original as its actually welded to the bracket rather than having the two studs to bolt it on.
