Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Optimize Suspension Performance for Maximum Control

Upgrade your Jeep Wrangler JK’s rear suspension with the Cruise Series Rear Lower Control Arms. Designed to outperform factory components, these arms deliver improved handling, better axle control, and increased off-road durability. Whether you're hitting the trails or cruising the highway, these control arms provide a smoother ride and enhanced stability while correcting suspension geometry.

What’s Included in the Kit?

  • Pair of Cruise Series Rear Lower Control Arms (CRS-J-JK-RL2)

Key Features and Benefits

  • Heavy-Duty Steel Tubing Construction – Built for maximum strength and longevity, ensuring superior performance over factory control arms.
  • Tapered Polyurethane Bushings – Absorb vibrations and provide better responsiveness than traditional rubber bushings.
  • Full Rear-End Suspension Solution – When paired with our Cruise Series Rear Upper Control Arms (CRS-J-JK-RU2), these lower control arms provide complete alignment correction, axle centering, and optimal suspension performance.
  • Corrects Pinion Angle – Adjustability allows for proper pinion angle correction when paired with our Upper Rear Control Arms, eliminating driveline vibrations for a smoother ride.
  • Improves Suspension Geometry – Helps re-center the rear axle and reduces tire wear and stress on suspension components.

Precise Adjustability for Lifts

The Cruise Series Rear Lower Control Arms are fully adjustable to accommodate lifts from 0 to 6 inches, allowing for:

  • Pinion angle correction when paired with our Upper Rear Control Arms.
  • Re-centered rear axle for better stability and handling.
  • Reduced stress on tires and suspension components, prolonging their lifespan.

For lifts beyond 6 inches, contact us for custom solutions.

Durable Two-Stage Powder Coating

Our control arms undergo a two-stage powder coating process for maximum corrosion resistance and long-lasting durability: Zinc primer base coat – Protects against rust and environmental wear. Durable top coat – Available in 10 color options to personalize your Jeep’s look.

Proudly Made in the USA

Manufactured in Orem, UT, our Cruise Series Rear Lower Control Arms are built to the highest American manufacturing standards, ensuring quality, reliability, and strength.

Effortless Installation

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

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.

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.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

The whole process was quick and painless. The products are top tier and when I reached out them for package update info, Korby Linscomb was very responsive, and got me the answers I needed the same day. Even when I emailed back to some additional info, he sent what I was looking for that same day. I love core 4x4 and will be giving them my business from now on.

First of I just want to say Great customer service korby Has helped me from the start and has not let me down! Reached out to him again today and he was able to warranty some parts out for me. As far as the quality of the parts.. excellent! The build quality is great. I can definitely tell a Difference from the cheap oem rear control arms to these and the pan hard bar. Color, From what I can tell it’s super durable been through a few mud holes on top of the daily road grime and after a quick wipe they still pop! Overall I recommend. Customer service is everything for me and it’s definitely there at Core 4x4.
