Before I buy a set of teryx coils I would like to know how much stiffer than the brute coils they are. I have used prowler coils on an AC with a 14" lift. They are way stiffer than the HL coils. I am getting ready to start building brute 4" lifts and would like to put a set on my brute to build the lift with. Most people that lift a bike put HL coils or spacers on.
