"When y'all increment the ride height, the end of the lower command arm drops … as y'all get over bumps the upper control arms motility … if information technology'south to shut to the strut, it'll rub/hit every bit you go over whatever bump in the road."

This rubbing could eventually lead to premature failure of the upper control arm and strut. The replacement of the control arms and struts volition so add together about $1,000 to your Jeep's maintenance bills.
Some Jeep users insist that this upgrade is not necessary until a elevator of three or four inches is used.
Marcus, a Jeep User who kept the stock command arms on his Wrangler later on a two.5 inch lift noted that his ride was "twitchy" on a Wrangler JK forum.
This is likely due to the improper camber, pulley, and pinion angles created by the change in the vehicle's height.
Learn more about the importance of these angles in the section below!
The Pinion, Caster, and Camber Angles
The pinion, caster, and camber angles are all used to measure your vehicle's alignment. When a vehicle is lifted, these angles are thrown off and will alter how the vehicle drives.
And then what are these angles and how do they relate to the command artillery of your Wrangler?
The pinion angle describes the divergence between the driveshaft and the pinion shaft. Cole from Kolar Tire and Motorcar explained that an incorrect pinion angle could lead to some serious damage it your Jeep.
"It'll shear the pinion gear i the differential, resulting in the differential internals 'exploding'."
Cole, Kolar Tire and Auto
There are two gear sets contained in your differentials: a carrier assembly and a ring and pinion gear set. If the pinion angle is not corrected after lifting your Jeep Wrangler, the pinion begetting will pause because information technology is not designed to deport the load from that direction.
As the pinion gear breaks pieces volition get between the teeth of the gears, damaging both sets of gears in the differential.
While non a literal explosion, this will commonly all happen at once because of the speed the gears move at while driving, producing a loud blindside.
Replacing the differential could cost a few hundred dollars to well over a thousand depending on the extent of the impairment.
The caster bending measures the gradient of the steering axis. Having an improper pulley angle will decrease stability too as change the direction that the tires prefer to drive (which is usually straight).
Meanwhile, the camber angle describes the tilt of the tire. The slant angle is used to calculate load distribution across the tire's tread. Incorrect slant angles will result in excessive wear on sure parts of the tire. An improper camber bending will as well cause the vehicle to pull to i side reducing the vehicle'southward treatment capability.

If any of your alignment angles are off, supervene upon the command artillery to ensure your vehicle continues driving properly for equally long as you take it.
While new command arms can assistance right some of the alignment angle issues described above, they could nonetheless be off depending on the elevator kit.
After installing the new control artillery check the pinion, pulley, and camber angles over again. If whatever of these angles are off from the factory settings, even it is just off by a degree or two, you can use an offset ball joint to correct the alignment.
"A lift kit will unremarkably have all the correct parts y'all need, but every at present and and then an offset brawl joint will exist required depending on the vehicle. You can't really tell unless it'southward on an alignment rack."
Cole, Kolar Tire and Auto

Be sure to set the new ball joint in the correct direction to correct the angle issue.
Reinstall the pieces that were removed earlier in the correct gild and then recalibrate the alignment angles. If the angles do not run across the manufactory specifications you volition demand to reposition the kickoff ball joint until they do.
