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.

Enhanced Vehicle Stability

Eliminate rear-end wandering and axle misalignment with the Cruise Series Rear Track Bar, engineered specifically for Jeep Grand Cherokee WK models from 2005-2010. This track bar ensures your axle remains perfectly centered, improving both on-road stability and off-road articulation. Designed to handle aggressive terrain, lifted suspensions, and high-speed handling, this heavy-duty upgrade is essential for maintaining tight, controlled suspension geometry.

What's Included?

  • Cruise Series Rear Track Bar (CRS-J-WK-RTB1)

Key Features and Benefits

  • Heavy-Duty Steel Construction – Built with high-strength materials to handle extreme loads and harsh conditions.
  • Adjustable for Perfect Axle Alignment – Corrects axle shift after lifting your vehicle, working with lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Reduces noise, vibration, and harshness (NVH) while ensuring a tight, responsive ride.
  • Greaseable and Rebuildable Joints – Allows for easy maintenance and extended service life, keeping your suspension performing at its best.

Enhanced Stability and Handling

A misaligned rear axle can lead to unpredictable handling, increased tire wear, and drivetrain stress. Our adjustable rear track bar eliminates axle shift, keeping your suspension geometry in check for smooth, predictable performance at all speeds and terrains. Whether you're tackling rocky trails or cruising on the highway, this track bar keeps your WK planted and controlled.

Recommended Pairing

Combine with the Cruise Series Rear Control Arm Set (CRS-J-WK-RS4) for a fully optimized rear suspension system.

Two-Stage Powder Coating for Maximum Durability

All components undergo a two-stage powder coating process for corrosion resistance and long-term durability. A zinc primer base coat provides superior rust protection, while the durable top coat—available in 10 color options—adds resilience and a custom look.

Made in the USA

Manufactured in Orem, UT, using high-quality, locally sourced materials to ensure precision, durability, and peak performance.

Optional Hardware Upgrade

Designed for easy installation using factory hardware. If you’re dealing with rusted or stubborn bolts, we offer optional Grade 8 hardware kits, available separately, to ensure a seamless installation.

In Conclusion

The Cruise Series Rear Track Bar delivers rock-solid rear axle control, reduced vibration, and improved drivability, making it a must-have upgrade for lifted Jeep Grand Cherokee WK models. By pairing it with our Rear Control Arm Set, you’ll experience unparalleled handling, stability, and long-term durability. Upgrade today and take control of your Jeep’s suspension for a smoother, more stable ride—on and off the road!

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.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!

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 purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

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 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!!
