Product Details

Camp Series Front Lower Control Arms - Compatible with Jeep Wrangler JK (CMP-J-JK-FL2)

Improve Stability and Control for Lifted Jeep Wrangler JKs

Upgrade your 2007-2018 Jeep Wrangler JK with Camp Series Front Lower Control Arms, designed to correct caster angles, improve stability, and enhance overall handling. Lifted Jeeps often experience wandering or a "following" effect on the road due to improper caster angles—our adjustable control arms restore proper alignment, reducing steering instability and improving road tracking.

Key Features and Benefits

  • Corrects Caster Angles for Lifted Vehicles – Adjustable design helps restore proper caster, reducing steering wander and improving high-speed stability.
  • Heavy-Duty Construction – Built from 1.75" OD DOM Tubing with a .313" wall thickness, offering exceptional strength for both on-road and off-road durability.
  • Premium Joint Design – Features tapered polyurethane bushings at the fixed end for vibration dampening and Johnny Joints at the adjustable end for superior articulation.
  • Adjustable for Lifts up to 6 Inches – Enables precise axle alignment and pinion angle correction for Jeeps with 0 to 6 inches of lift. Contact us for options beyond 6 inches.
  • Enhanced Off-Road Flexibility – Allows for maximum articulation while preventing binding, ensuring superior performance on uneven terrain.
  • Pairs Perfectly with Our Front Upper Control Arms – For complete caster correction and optimized axle positioning, we recommend pairing these with our Camp Series Front Upper Control Arms (CMP-J-JK-FU2).

Restore Caster Angles and Improve Handling

When lifting a Jeep, factory caster angles become insufficient, leading to unstable steering, excessive body sway, and poor high-speed handling. By correcting control arm geometry, these adjustable lower control arms recenter the front axle, optimize steering feel, and eliminate wandering. Combined with our Front Upper Control Arms, this setup provides a complete solution for handling precision.

Two-Stage Powder Coating

For maximum durability and corrosion resistance, our control arms undergo a two-stage powder coating process:

  • Stage 1: A zinc primer base coat to protect against rust and environmental damage.
  • Stage 2: A top coat available in 10 colors, providing additional protection and allowing you to customize your Jeep’s appearance.

Made in the USA

Manufactured in Orem, UT, our Camp Series Control Arms reflect American-made quality and craftsmanship. By sourcing materials locally and overseeing production in-house, we ensure durability, performance, and competitive pricing.

Optional Hardware Upgrade

Designed for easy installation using factory hardware, these control arms provide a straightforward upgrade. If dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, for a hassle-free installation.

  • Vehicle Fitment: Jeep Wrangler JK 07-18 – Precision-engineered for all trims to enhance suspension control, handling, and off-road capability.

  • CORE Advantage: Restores proper caster angle to enhance steering response, reduce wander, and improve high-speed stability for a smoother, more controlled ride.

  • Adjustability: Fully adjustable to accommodate 0–6” lifts, allowing precise axle alignment, caster correction, and optimized suspension geometry.

  • Construction: Built from 1.75” OD .313-wall DOM tubing with polyurethane bushings at the fixed end and Johnny Joints at the adjustable end.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

I have nothing but great things to say about this company and their customer service. If you like American made products backed by warranty and amazing customer support, this is the company for you. I have a Lexus GX470 and love their rear control arms.

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

I ordered a part for my 03 Jeep TJ and all I can say is wow! Korby at Core 4x4 is a total rockstar!! There was a glitch with my payment and within minutes, Korby reached out to me to get it fixed, then sent my receipt with the tracking number. I lost the number and reached out to him during the Holidays and got a rapid response with the number again. I can’t say enough about the customer service and the quality of parts. Thank you!!

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!
