Update: I've been adjusting and tuning my new torsion bars over the past couple days and am very happy with the end result. You have to keep cranking on them to get the spring out of the front end. I am not sure I would intall them if you haven't lifter your truck. I have OME 919 springs on the back which gives me a wheel opening measurement (with 33s) of 38 1/2 inches. With the bars ajusted up front I measure an even 38". I am getting excited to see how it will perform for the next race, looks like there is goint to be a LOT of air time in this one.
