The spring capacity of the torsion style ramps springs like the part # M394FR that you mentioned is how much lifting strength it is capable of if adjusted for it. This spring has a 185 lb capacity but could have a lower tension used if that's too much for the door. Since we recommend having a pro with experience winding garage door springs install these they'd be able to set the best amount of tension to use.
