When you're on the trails, wheel articulation counts as much as ride height does. More wheel travel means less body roll, and less body roll means a successful climb or descent. Tires belong planted on the ground as flat as possible, not spinning in the air freely as you struggle to climb out of a Jeep that landed on its side. Experienced off-roaders know that while it's easy to handle visible rises and drops, being truly prepared for the trails means having a vehicle that won't lose control over pits hidden by grass or by water that's deeper than it appears.
Rubicon Express spent many hours of engineering to create a complete lift kit that provides a higher level of dexterity for your wheels. The goal when creating the Jeep JK Super-Flex 3.5" and 4.5" lift kits was to provide the off-road enthusiast with high-quality components that are not only beefier than original equipment, but that provide a wider range of pivot angles. The kit allows more wheel travel than stock equipment, and it does so while keeping tires planted as flat as possible – a claim that most lift kits cannot make. Lower and upper control arms simply outperform factory ones in every way with a Polytetramethylene Ether Glycol (PTMEG) bushing at one end and an adjustable spherical-shaped ball joint at the other. PTMEG has the highest durability rating of all bushing materials available, and is far more resilient when it comes to squish resistance. An adjustable front track bar allows steering to be centered any time after the lift kit is installed, and the threaded rod end is easily replaceable should it become damaged during extreme use. If your Wrangler JK was not equipped with optional factory sway bar disconnects, this kit includes the assemblies you need to add this articulation-enhancing feature. Longer-length braided stainless steel brake lines are more durable and resistant to deterioration than factory OEMs are, and this upgrade alone can be worth its weight in gold over rough terrain.
This is the type of off-road layout the factory dreams of building but doesn't because of cost constraints, and Rubicon Express gives you the highest number of replacement parts for your money. If your JK is still under its new car warranty, factory mounting points can be used for the control arms – so there is no need to lose any warranty coverage by cutting them off the way some kits require. And while reviewers who have driven Jeeps equipped with the Super-Flex Lift Kit have been impressed by its off-road performance, they were simply amazed at how greater articulation maintains stock levels of on-road comfort during everyday use. Rubicon Express stands behind all components with a limited lifetime warranty.1,649.99 2,219.99
