Rusty’s 4" Advanced Kit for the New JT Gladiator was specifically developed to deliver the on-road performance people expect from the JT combined with the ultimate flex and control off the pavement. We weren't the first JT 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.
It was our job to design a complete suspension package that would ride as good if not better, not lose any of the outstanding road handling manners, while increasing 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 hours on the computer designing with 3-D modeling. Now we feel we have designed and engineered one of our best kits yet.
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. Rusty’s JT coils springs were developed specifically for the JT Gladiator so that you can be assured the ride height of the vehicle will be correct, with no cheesy offset spacers needed to keep the vehicle level or reduce spring bowing. The Rusty’s 4" kit will give you the clearance on a JT Gladiator to fully flex it with 37-inch tires off road and not have any fender rub, no inner fender rub. You can also easily run a 40-inch tire, but bump stops are recommended for vehicles going off road.
