We figured we could push the front axle in our TJ forward about an inch. The JKS control arms can be set a little shorter than stock or a couple inches longer than stock. To stretch our front axle forward a little, we simply set the JKS lower and upper control arms one inch longer than the stock arms we were removing. Will this make a huge difference in performance? Probably not, but it can’t really hurt either, and it will allow for more tire clearance at the rear of the front fenders. Bonus! In the end we had to remove about 1⁄2-inch from our stretch as the track bar was hitting the front diff cover on compression. Our Jeep does not have a front sway bar to hit, nor a stock track bar or track bar bracket.
