Caster Correction Axle Centering for Better Drivability

When lifting a Jeep Wrangler JK, the front axle naturally shifts off-center, and the caster angle decreases, leading to poor steering response, increased wandering, and a lack of stability. Correcting these issues is crucial for maintaining proper drivability.

Caster Angle Restoration

The lower control arms play a key role in regaining caster, helping the front tires return to center after a turn and preventing the Jeep from following road ruts or wandering. Proper caster correction improves straight-line stability and reduces steering effort, making lifted vehicles safer and more predictable to drive.

Axle Centering Alignment

The upper and lower control arms work together to recenter the front axle, ensuring proper wheel positioning for correct steering geometry and minimized tire wear. When paired with our Camp Series Front Track Bar, you achieve full front suspension correction, eliminating handling inconsistencies caused by lifting your Jeep.

Built for Strength and Performance

Crafted from heavy-duty DOM Tubing with a .313" wall thickness, these control arms are engineered for extreme durability. The design features: Johnny Joint at the adjusting end for maximum articulation and flexibility off-road. Tapered polyurethane bushing at the axle end for vibration dampening, reducing road noise while maintaining a smooth ride.

This combination delivers the best of both worlds—enhanced articulation for off-road performance and exceptional road comfort.

Adjustability for Perfect Alignment

Our adjustable control arms accommodate lifts from 0 to 6 inches, allowing precise adjustments to caster, pinion angles, and axle positioning. With full adjustability, you restore the proper geometry lost during a lift installation, improving your Jeep’s handling, reducing stress on suspension components, and maximizing tire longevity.

For lifts beyond 6 inches, contact us for additional options and support.

Resilient Two-Stage Powder Coating

To ensure long-term durability, our control arms undergo a two-stage powder coating process, providing superior corrosion resistance and an eye-catching finish: Zinc Primer Base Coat – Protects against rust and environmental wear. Top Coat in 10 Custom Colors – Allows you to customize the look of your suspension while adding an extra layer of durability.

Proudly Made in the USA

Every Camp Series product is manufactured in our Orem, UT facility, ensuring the highest standards of quality and craftsmanship. By sourcing raw materials locally and maintaining in-house production, we deliver superior products while supporting American manufacturing.

Optional Hardware Upgrade

These control arms are designed to install easily using factory hardware. However, for rusted or stubborn bolts, we offer optional new Grade 8 hardware kits (available separately) to ensure a seamless installation.

In Conclusion

Upgrading to our Camp Series Front Control Arms Set is the best way to restore proper caster, realign your front axle, and improve your Jeep’s drivability after lifting. Whether you're looking for a smoother ride on-road or enhanced articulation off-road, these control arms provide the perfect balance of strength, adjustability, and long-lasting performance.

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

Great company. Highly satisfied with Core 4x4 customer service. Had some bushings fall apart around 600 miles from home. Called and spoke with Korby Linscomb on Thursday, late in the afternoon. He was able to get my bushings sent across country overnight at a very reasonable rate. Had me up and running by Friday evening with enough time to enjoy the Great Smoky Mountain Jeep Invasion. Thanks Guys!

Installed the full kit on my XJ. Ride quality is night and day better than what I had before. The articulation on the trail is insane. These guys know what they are doing. Already recommended Core 4x4 to everyone in my club.

I ordered the jeep xj long arm lift kit. Control arms showed up first they turned out amazing!! Had some issues with the powder coating on the cross member and sent korby and the team at core4x4 an email. They got right on making me another cross member and sending it out. I appreciate all the help they've given me along the way. Very fast response thru emails. Build quality seems to be pretty dang nice!! Can't wait to install it and enjoy it!

I contacted these guys on a Saturday through email and needed some control arms by the following weekend, Spence got back with me and told me he would make sure the order got shipped out on Monday, they got busy and wasn’t able to ship the package out so he got back with me that evening and upgraded my shipping for free and shipped out the next day, only because he told me he’d make sure I’d have them by the weekend! This company sticks to their word! The customer service from these guys are unmatched and they will have another lifetime customer here!
