Geometry Correction Brackets or Adjustable Control Arms – Which is Better for Your Jeep Wrangler or Gladiator?
DOES A LEFT KIT AFFECT HANDLING?
Whether you want to add larger tires to your vehicle or want more clearance for rock crawling, installing a suspension lift kit to your Jeep Wrangler or Gladiator is a popular aftermarket upgrade. However, adding a suspension lift kit to your rig can affect the steering of your vehicle. Whether you’re on the trail or on the highway, you may notice that the higher center of gravity of your vehicle has a direct effect on how it handles.
Keeping the factory control arms on a lifted Wrangler or Gladiator can lead to alignment issues and reduce the performance of your Wrangler, yet replacing the factory control arms or adding geometry correction brackets can counteract the effects of lifting your rig. While both options can adjust the vehicle’s caster angle, each part does it in different ways. To decide which option is right for your Jeep, check out this comparison of geometry correction brackets and adjustable control arms.
GEOMETRY CORRECTION BRACKETS
Designed to keep the control arms at factory angles, geometry correction brackets can improve the handling of your Jeep Wrangler after adding an aftermarket lift kit. A cost-effective alternative to adjustable control arms, geometry correction brackets reduce brake dive and allow for proper caster angle. Ideal for vehicles that spend a majority of their time on city roads and highways, geometry correction brackets deliver improved handling and steering.
Advantages:
- Easy to install
- Cost-effective upgrade
- Keeps control arms at factory angles
- Helps improve the ride feel over stock
- Works at various heights from 2" to 4.5"
Disadvantages:
- May hang down a bit and take away from clearance
- Stock control arm won’t have the same flex as an adjustable control arm
ADJUSTABLE CONTROL ARMS
For lifted vehicles that spend a significant amount of time on the trail, adjustable control arms can be a great option for resolving geometry issues on your Jeep Wrangler. Adjustable control arms help correct caster angles, centers the axle, and reduces the range of travel. You can tweak the settings on an adjustable control arm to get them dialed-in to the ride and feel that you want, getting the caster and pinion angles perfect.
Advantages:
- Perfect for the trail
- Adjustable to set caster and pinion angles
- Works on vehicles from stock height to 4.5"
- Can upgrade all the arms at once or on an individual basis
Disadvantages:
- Needs slightly more maintenance than a stock control arm, but are rebuildable with parts from Rancho®
