In the rocks, there was absolutely no comparison between the modified and factory versions. While a Rubicon is competent in the rocks for such a low-slung vehicle, a Sahara, with its street tires, low ride height, and fixed factory sway bar is simply not equipped for this type of terrain out of the box. It is amazing what a couple inches of ride height, a little flex, and some aggressive tires can do. With the JKS Quicker Disconnects, we can have the sway bar disconnected in less than two minutes, and since we opted for the lanyard kit, we can easily tuck the factory sway bar out of the way. Suspension flex is impressive. Even though the base Jspec kit does not focus on wheel travel per se, it is a great demonstration of how a moderate suspension lift and the proper tires can really make a JK Wrangler live up to its potential.
