  • Heavy-Duty Steel Construction – Delivers superior strength and longevity compared to stock components.
  • Adjustable for Precise Suspension Tuning – Corrects pinion angles and recenters the rear axle, accommodating lifts from 0 to 6 inches.
  • Tapered Polyurethane Bushings – Enhances ride comfort, minimizes road noise, and reduces harshness, outperforming standard rubber bushings.

  • Recommended Pairing – For a complete rear suspension upgrade, pair with the Cruise Series Rear Track Bar (CRS-J-WK-RTB1) to fully optimize rear axle stability and alignment.

Reduced Noise, Vibration, and Harshness (NVH)

Our Cruise Series polyurethane bushings significantly reduce road noise, vibrations, and harshness, creating a quieter and smoother ride both on and off the road.

The greaseable and rebuildable design ensures long-term durability, making this kit a cost-effective solution for performance and comfort.

Two-Stage Powder Coating for Maximum Durability

To withstand harsh environments and prevent corrosion, all components undergo a two-stage powder coating process: Zinc primer base coat for superior rust protection. Durable top coat, available in 10 color options, for added resilience and customization.

Made in the USA

Proudly manufactured in Orem, UT, using high-quality, locally sourced materials.

Optional Hardware Upgrade

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!

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.

The customer service is first class. I had an issue with a track bar I installed on my F350. I don’t have any other Core 4x4 parts yet, but with the way I was treated, I know their parts are well done, because they went above and beyond to make sure I was made whole. They wouldn’t be in business if they had to take care of a lot of people like they took care of me. Will definitely be back when it’s time to build the Jeep!
