The Ultimate Trailing Arm Solution for Lifted Trucks

Take your truck’s performance to new heights with the CORE 4X4 Universal Trailing Arm Kit. Specifically engineered for lifted trucks, particularly those with rear lift blocks, this heavy-duty weld-on kit resolves common suspension issues like axle wrap, wheel hop, and driveline vibrations. Designed for off-road enthusiasts and everyday drivers alike, this kit provides unmatched stability, balance, and durability.

This all-inclusive kit ensures a precise and seamless installation for a wide range of trucks.

Robust Construction for Maximum Performance

Solid 7075 Aluminum Trailing Arms

Built with 2” solid 7075 aluminum, these trailing arms are designed to flex upon impact, preventing permanent bending. The aluminum’s unique “memory” allows it to return to its original shape, maintaining traction and performance even under extreme conditions.

1/4” Plate Steel Weld-On Brackets

The heavy-duty 1/4” plate steel brackets provide strong, reliable anchor points, ensuring your suspension stays secure in the toughest environments.

Heavy-Duty FK Rod Ends

Equipped with durable FK rod ends that require no lubrication, this kit offers low-maintenance operation with enhanced articulation and longevity.

Durable Powder Coating for Long-Lasting Protection

The trailing arms undergo a resilient two-stage powder coating process: Zinc primer base coat provides exceptional corrosion resistance Durable top coat—available in 10 vibrant colors or custom options—enhances both durability and aesthetics

Proudly Made in the USA

Crafted at our Orem, UT facility, the CORE 4X4 Universal Trailing Arm Kit is a testament to American engineering excellence. By sourcing local materials and keeping production in-house, we deliver superior quality and support American manufacturing.

Optional Hardware Upgrade for Advanced Enthusiasts

While this kit requires cutting and welding expertise for installation, all necessary hardware—including Grade 8 bolts—is included to streamline the process.

 

  • Vehicle Fitment: Universal – Designed for lifted trucks with rear lift blocks to eliminate axle wrap, wheel hop, and driveline vibrations, improving stability and traction.

  • CORE Advantage: Enhances traction, reduces wheel hop, and provides superior suspension control for towing, hauling, and off-road use. Keeps the rear suspension stable, ensuring smoother handling on any terrain.

  • Adjustability: Fully adjustable design accommodates various lift heights, allowing fine-tuning of pinion angle, rear suspension geometry, and axle positioning for optimal performance.

  • Construction: Built with 2” solid 7075 aluminum trailing arms for unmatched durability and impact absorption, 1/4” plate steel weld-on brackets for secure mounting, and heavy-duty FK rod ends for articulation and longevity.

  • Two-Stage Powder Coating: Zinc primer base and top coat available in 10 vibrant colors protect against corrosion and allow for personalized styling of your rig.

  • Warranty and Origin: Proudly manufactured in the United States, our product includes a lifetime warranty on all non-wear items, providing you with confidence and peace of mind in your purchase.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

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!

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!

Had a worn out set of rear upper control arms on my TJ. These were old rubicon express long arms. can’t buy replacements and no one makes a direct fit replacement. Talked with Korby at core off road sent some measurements and photos and a week later new arms showed up. Packaging was perfect fit was perfect. Would highly recommend giving these guys a call.

First and foremost would like to say that Core4x4s customer service is top notch and they definitely stand behind their warranty on products! Highly recommend using them for any of your off road needs! It’s rare to find a company now a days that backs their products and they do! Had a few issues with mounts and control arms and they handled it without hesitation! Thank you!

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.
