Cap Auto Produckets
I totally agree with re using the factory suspension and K frame. It can be upgraded with stitch welding and boxing/gusseting as well,and wont cost you a thing other than welding material.
There is an advantage in running alterk etc,with header clearance being the main thing. Other than that,I see no point in spending thousands of $$ when a stock suspension upgrade will give you as good or better handling and no safety issues.
That being said I do have an rms inboard spring kit that looks to be very good quality. The cap stuff is a risk,seeing how there is a proven history of product failure.
However,neither brand is dot approved right?
