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.

Each rebuild kit includes all necessary components to replace and restore wearable parts.

Use the vehicle selector on our website to shop by your year, make, and model. On product pages, use the kit builder to select your color, series, and any add-on options, then add to cart — you’ll confirm your lift height at checkout. If you need help, call or email our team.

Standard orders typically ship within 1–3 business days of ordering. Custom color orders take approximately 5–10 business days. Because everything is built in-house, we can turn orders quickly even for custom specifications.

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.

I’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

Ran into an issue with a part that I ordered. Got ahold of them explained to them the issue I was having and they jumped in and got the issue fixed. Hands down the best customer service I have ever dealt with. The parts are hands down amazing. Highly recommend.

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!
