Rusty’s 2" Advanced Kit for the New JL Wrangler was specifically developed to deliver the on-road performance people expect from the JL combined with the ultimate flex and control off the pavement. We weren't the first JL kit to be released, but we feel we have the best. Where others rushed their prototypes to market with little to no testing, we invested the time and effort to thoroughly test everything. The result is what we feel is the best kit in the industry, and there's no need to accept anything less.
In late 2017 we started on coil spring and shock designs as we got small bits of information. In late January 2018, we received our first Rubicon and a Sport, this is when we got ready to get to work. With the Jeep JL being totally redesigned from the departing JK Wrangler, everything was different. Ride quality, handling, and suspension travel were greatly increased on the new JL Wrangler, but it also meant that nothing that was learned from the JK applied to the JL. It was our job to design a coil spring that would ride as good if not better, not lose any of the outstanding road handling manners, increase the lift height for larger tires and add more suspension travel. We knew the challenge ahead of us wasn’t going to be quick, nor was it going to be easy. We also spent countless man-hours on the computer designing with 3-D modeling. Now with over a year in design and real-world testing, we feel we have designed and engineered one of our best kits yet.
We developed a dual rate progressive front and rear coil spring. These springs were started from scratch and are a totally different design and spring rate from the departing JK. This extensive development takes time and is costly to design and build. Beware of many manufacturers and their one-size-fits-all mentality by using springs that are designed for other applications. It's certainly cheaper to borrow designs from previous platforms, and it gets you to market more quickly, but that doesn't make it right.
