Precision Control for Pinion Angle Rear Axle Alignment

Maximize your Ram 1500’s performance with the Trail Series Adjustable Rear Upper Control Arms, engineered to fine-tune rear axle alignment and pinion angle adjustments. Designed to work in conjunction with our lower rear control arms, this setup ensures maximum traction, stability, and drivetrain efficiency across all terrains—from highways to rugged off-road trails.

What’s Included?

Trail Series Adjustable Rear Upper Control Arms (TRL-R-15-2009-RU2)

Key Features Benefits

Heavy-Duty DOM Tubing Construction – Built from 1.75" OD, .313" wall DOM tubing for exceptional strength and durability.
Polyurethane Johnny Joint Combo – Features high-grade polyurethane bushings at the fixed ends for reduced NVH (Noise, Vibration, and Harshness) and Rock Jock Johnny Joints at the adjustable ends for maximum articulation and flexibility.
Pinion Angle Adjustment for Driveline Efficiency – Adjustable to correct pinion angle, reducing driveline vibrations and premature wear for a smoother power transfer and extended drivetrain life.
Recommended Pairing – For complete rear suspension control, pair with Trail Series Adjustable Rear Lower Control Arms (TRL-R-15-2009-RL2) to eliminate wheel hop, optimize suspension geometry, and maintain proper axle alignment.

Eliminate Driveline Vibration Improve Rear Suspension Control

Factory upper control arms lack adjustability, making pinion angle corrections impossible after lifting or lowering your truck. By installing adjustable upper control arms, you eliminate vibration-causing misalignment, ensuring smooth acceleration, extended U-joint life, and optimal drivetrain efficiency. When paired with adjustable lower control arms, you gain full control over axle positioning, reducing suspension flex and eliminating wheel hop.

Highly Durable Two-Stage Powder Coating

Zinc primer base coat for maximum rust resistance
Durable topcoat available in 10 color options for a customized look

Optional Hardware Upgrade

Designed for installation using factory hardware, but for enhanced durability and a secure installation, we offer an optional Grade 8 hardware kit (sold separately).

Proudly Made in the USA

Manufactured in Orem, UT, every CORE 4X4 component meets strict quality control standards for precision, strength, and long-term durability.

Final Thoughts

The Trail Series Adjustable Rear Upper Control Arms are a must-have upgrade for lifted or lowered Ram 1500 owners looking for driveline stability, reduced vibration, and enhanced suspension control. Pairing these with adjustable lower control arms provides total control over axle alignment, ensuring your truck stays planted and smooth under all conditions.

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.

Their website estimated 2 days to get my parts but actually took 11. No communication to let me know what’s going on. Parts were missing. Some days they answer questions, some they don’t. Didn’t let me know I’d have to alter stock bolts to fit their parts. All around just seems like they don’t care.

Ive had the front adjustable control arm kit in bright green for my 1996 ZJ. Ive had the kit for about a year now and i have to say, im extremely impressed, over 1000 miles off-road and roughly 20,000 miles on the highway. These control arm kits for any vehicle built by core 4x4 are well worth the money, just be aware thereight be some minor scatches or chips from shipping ( but who should care about that if you're beating the crap out of em' they way they were built and designed for)

Great products they sell, got a crawl series long arm kit for my xj and it has held up quite nice, they are beefy, and for what ever reason they fail it has a great warranty with a customer service to match, when someone asks what control arm kit to buy I always recommend core 4x4

Great company! I have used there products consistently with no complaints with quality you can see and feel. From my experience, their customer service is also amazing. Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

I've been having trouble with the track bar (on my 2nd gen Dodge) since I installed the 3rd gen Synergy adapter bracket and a 3rd gen stock bar.. oddly, they call it a '3rd gen bracket' and the stock 3rd gen bar doesn't quite fit, making contact with the bracket. I had attempted to clearance the bracket but it was still making contact and I could feel it over large bumps. I reached out to a lot of companies, but Core 4x4 offered to make a custom bar for the application with adjustability and dual Johnny joints. The first pass on it didn't work but they sent me out another passenger side end that made it fit incredibly well. This was all done solely over email/descriptions/pictures/measurements. Bar is super high quality and heavy duty, made in the US by a family owned company and carries a lifetime warranty. The customer service was responsive and superb, and the price was a lot less than I expected.

Bought a new 2019 Ram 1500. Had bad rear wheel hop since new, got all four core 4x4 control arms and it fixed the issue. Thanks

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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’m extremely impressed with Core 4x4. The quality of their parts is outstanding — everything feels solid, well‑built, and engineered with real attention to detail. Shipping was fast and everything arrived perfectly packaged. Their customer service is just as good as their products: responsive, helpful, and genuinely committed to making sure you get exactly what you need. Overall, a top‑tier experience. I’ll definitely be buying from them again. Specially thank you Mr. Linscomb from Core 4x4. Arturo M.
