PRO-ALIGNMENT Adjustable Arms and Hardware
Why are Alignment Parts Essential
Alignment kits are necessary when lifting or lowering vehicles because changes in the height of a vehicle can affect the alignment of its wheels. If a vehicle is lowered or lifted beyond a certain point, factory alignment specifications will not be achievable which can negatively effect handling. These alignment kits not only allow the adjustment of a vehicle’s camber back to factory specifications, but they also allow an experienced chassis tuner to utilize the increased adjustment range to achieve a more performance-oriented alignment.
Inner Edge Wear - Improper Alignment Specs
When an alignment is out of spec, uneven tread wear and accelerated tire life are most likely to occur. These are signs of excessive toe and camber values.
Even Edge Wear - Proper Alignment Specs
When an alignment is within spec, tread wear should be spread evenly across the entire width of the tire.
Upper & Lower Control Arms
Control arms are used to connect the suspension to the car's chassis. They help to control the motion of the wheels and keep them aligned properly. These have a slotted adjustment for camber and are typically located on the front of most suspension layouts.
If you’ve lifted or lowered your vehicle, factory control arms just aren’t designed to keep up. Our heavy-duty control arms are made to:
- Correct suspension geometry for proper alignment
- Improve steering feel, return-to-center, and high-speed stability
- Increase caster and camber for better tire wear and control
- Eliminate squeaks and reduce maintenance with sealed bushings
Heavy-Duty Off-Road Upper Control Arms (UCAs)
Our heavy-duty tubular upper control arms (UCAs) are engineered for off-road performance, improved handling, and long-term reliability — designed specifically for modern suspension setups running 2.0" or 2.5" coilovers.
- Oversized 1-3/8" DOM tubing designed to handle extreme off-road use is the largest on the market.
- Shot-peened and tempered for durability, a process unique in the market. Enhances fatigue life and strength over time — especially under stress.
- Sealed mono-ball pivot bushings require zero-maintenance while providing quiet operation. Outperforms urethane or rubber bushings in articulation and lifespan.
- OE+ style ball Joints that are reliable, replaceable, and compatible with daily driving and off-road use. Designed for quiet operation and long service life.
Eibach UCAs are engineered to work with any 2.0" coilovers or long-travel 2.5" shocks from all the top brands. Our arms maintain proper alignment and get the most out of you vehicle's suspension travel.
What is Camber?
The camber angle is the angle of the wheel relative to the road surface. If the top of the wheel is leaning towards the car, the wheel is said to have negative camber. If the top of the wheel is leaning away from the car, this is positive camber. Most vehicles run either zero or negative camber values.
What is Caster?
The caster angle is the angle of the steering axis relative to the vertical axis of the car. Most vehicles have some value of positive caster, meaning that the steering axis is angled towards the back of the car. This angle affects stability, stering response and steering return rate among others.
Camber Bolts
Camber bolts are eccentric bolts that are added between a vehicle's strut and hub assembly. While they do not give the same range of adjustment as an adjustable control arm, they are easy to install and are a lower cost alternative.
Camber Arms
Similarly to a Control Arm, Camber Arms help to adjust the angle of the wheels as well. Proper camber arm adjustment plays an important role in improving a vehicle's handling and stability. These are typically located on the rear suspension of most vehicles.
