  • Cruise Series Front Lower Control Arms (CRS-J-WJ-FL2)
  • Mounting Spacers (4)

Key Features and Benefits

  • Increased Strength and Durability – Built from heavy-duty steel tubing, these control arms provide superior resistance to flex and wear.
  • Precise Adjustability – Fully adjustable to accommodate lifts from 0 to 6 inches, ensuring proper alignment and axle centering.
  • Tapered Polyurethane Bushings – Engineered for improved stability, responsiveness, and ride quality compared to factory rubber bushings.
  • Recommended Pairing – For a complete front-end suspension upgrade, pair with the Cruise Series Front Track Bar (CRS-J-WJ-FTB1).

Optimized Caster Alignment and Handling

Lifting a Jeep Grand Cherokee WJ without correcting caster angles can lead to unstable steering, wandering at highway speeds, and poor handling. Our Front Control Arm Set allows for precise alignment correction, ensuring smooth tracking and predictable steering—whether you're on the road or hitting the trails.

When combined with our Cruise Series Front Track Bar, you achieve a fully dialed-in suspension system, ensuring maximum stability and axle control.

Two-Stage Powder Coating

To provide maximum protection against rust and corrosion, our control arms undergo a two-stage powder coating process: Zinc Primer Base Coat – Forms a corrosion-resistant barrier. Durable Top Coat – Available in 10 color options for added protection and customization.

Made in the USA

All Cruise Series components are proudly manufactured in Orem, UT. By sourcing our materials locally and overseeing every step of the production process, we ensure unmatched quality and durability.

Optional Hardware Upgrade

  • Our Front Control Arm Set installs using factory hardware with the necessary spacers included.
  • For rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a smooth, hassle-free installation.

In Conclusion

Upgrading to the Cruise Series Front Control Arm Set means eliminating steering instability, regaining proper caster alignment, and improving both ride quality and durability.

For the best possible front-end suspension setup, pair these control arms with our Cruise Series Front Track Bar (CRS-J-WJ-FTB1).

Upgrade today and experience the difference in control, stability, and handling on any terrain!

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.

Have full upper/lower CA set on both front and rear axles on a 96 ZJ. These are the rubber bushing sets not joint sets. I have beat the hell out it in the Nevada desert for 2 years and has been great. I don’t go fast but I do articulate suspension a lot. Super solid and haven’t any issues. Just inspected the entire set recently due to some banging under it. Turns out the banging is lower rear shock bushings. Inspected each CA along the way nothing. Aside from dirt and obviously winter roads and what not still in excellent condition, bushings are solid like the day they were installed. I’ll add that I’m about tapped on a short arm at 4.25(less with settle) so the front CA’s get beat on just from that, still they’re like new. Paint is great condition, this set is red. I would definitely buy again. Another plus for me, Utah isn’t local necessarily, but it’s nice to support businesses closer to me.

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!

First off amazing products. I got a set of adjustable control arms for my XJ and it is so nice to be able to dial in caster and pinion angles. A quick call and I was able to purchase an adjustable track.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

Have yet to get to try them but I bought some upper, and then later , lower control arms for my 03 rubicon. The pricing is very fair, so fair I was hesitant to even purchase. When the product came in I was happily mistaken. These are some beefy units with an incredible warranty! I’m very excited! I went with the “Camp”series as I mostly daily it. I have trouble with the shipping at times when I ordered but Corby is quick to notice things and help communicate the solution. Looking forward to buying more parts!

I don’t write reviews often, but Core 4x4 absolutely earned this one. I recently ordered leaf spring mounts and realized after the fact that I messed up my order. Totally my mistake. Instead of giving me the runaround or pointing at a return policy, Core 4x4 emailed me back and forth, worked through exactly what I was doing with my build, and made sure I ended up with the correct parts. That kind of customer service is rare these days — especially in the off-road world where a lot of companies stop caring once the order is placed. The parts themselves are exactly what you hope for: solid, well-made, confidence-inspiring hardware that looks like it belongs under a vehicle that actually gets used. You can tell these are designed by people who understand suspension geometry and real-world abuse, not just CAD screenshots. Mistakes happen — especially on custom or modified builds — and Core 4x4 handled mine like pros. Fast responses, clear communication, and a genuine effort to help me get it right. If you’re on the fence: don’t be. Core 4x4 is the kind of company you want backing your build — the kind that treats customers like fellow enthusiasts, not order numbers.

Korby was a great help with getting me a set of leaf springs for my Cherokee. Great customer service and an awesome product all made in the USA. Proud to support and rock their parts on my vehicle. 👍 …
