my uncle has a 500 magnum and was wondering if there is any way to make the 4wd engage when you turn the switch to 4wd and not just when the rear wheels spin. the problem is when going down a hill the machine wants to slide when allowing the engine to hold back, and we would like to get the front to engage whenever the 4wd switch is on thanks

 

What he wants cant be done.But with a stiffer secondary spring to backshift faster will helpBut again all he has to do on down hills is gas it and let off (blip the throttle)
