The new All-Terrain Lift Kit from Eibach offers suspension lift options for two-door and four-door Jeep Wranglers that are looking to improve off-road capability and make room under the Jeep JK for larger tires and wheels. This lift kit will raise the front between 2.5" and 3.5" and raise the rear approximately 2" to 3" so you have room to fit 35" tires on wheels that have about a 4.5" backspacing. 2012+ Jeeps with the 3.6L Pentastar engine will need some modification to the Y-Pipe in the exhaust where it crosses under the front driveshaft due to a more extreme angle. When you flex the front suspension, the driveshaft gets closer to the crossover pipe in the exhaust, which can make contact on a lifted Jeep and eventually wear down the boot in the middle of the stock driveshaft and cause it to fail.
In four-door JKs, there are aftermarket Y-pipes that will fix this issue, however the two-doors will have to adjust it with an exhaust spacer or Y-pipe modification. You could also fix this with just a smaller diameter, stronger aftermarket driveshaft, since the stock one is so large. When you lift a two-door, the driveshaft angle is more extreme than that in the four-door, so the front driveshaft will likely need to be replaced in a two-door before a four-door. Many people have lifted Jeeps with stock driveshafts for several years before seeing any issues, but in my own JK, I split the boot on the CV joint going into the transfer case in just six months. Beware that new driveshafts may be necessary before long.

Our sale of this kit also includes an alignment kit to adjust for caster angle (for bump-steer reduction) and pinion angle to eliminate vibration in the driveshaft and reduce that angle in the driveshaft. Some kits in the market will address this with geometry brackets that essentially move the control arms to adjust for caster and pinion. These are good options for everyday driveability, but for more off-road durability, you will want to get some adjustable control arms to address caster, pinion and axle position. The easiest way to do this is with front and rear upper adjustable control arms, or many people will install lowers in front and uppers in back, either way is sufficient.
When you lift the suspension with stock fixed-length control arms, the axles rotate down and toward the middle, so to re-center the axles, you would need a set of upper and lower adjustable control arms. The front adjustable track bar and rear track bar relocation brackets are to re-center the axles laterally so when you look at the Jeep head on, one side won't appear to have the wheels sticking out further than the other. The last thing this comes with are the bumpstop spacers to keep the bigger tires from smashing the fenders and overcompressing the shocks and the sway bar end links that allow for better flex and smoother on-road handling.
The most important thing to remember when installing a new lift kit like this is to leave the suspension bolts a little loose while the Jeep is jacked up in the air, and wait until it is resting on the ground under its own weight to actually torque everything down to spec. The bushings can get some bind in them if you fail to do this, and this can quickly lead to the infamous "death wobble."
Lastly, the installation instructions from Eibach are awesome. I've installed a lot of parts on many Jeeps, and it is rare to find parts with installation instructions that are as detailed and have color pictures with this much clarity and comprehensiveness!
