Complete Front-End Suspension Upgrade for Strength, Stability Control

Upgrade the front suspension of your Dodge Ram 3500 (2003–2007) with the Trail Series Adjustable Front Suspension Kit. Designed to correct caster, improve axle positioning, and eliminate steering instability, this kit is a significant improvement over factory components. Whether you're towing, hauling, or tackling rough terrain, these adjustable control arms provide exceptional durability, precision adjustability, and long-term suspension performance.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (TRL-D-35-2003-FU2)
  • Adjustable Front Lower Control Arms (TRL-D-35-2003-FL2)

Key Features Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM tubing with a 5/16” wall thickness, ensuring unmatched strength and longevity.
  • Hybrid Joint Design for Strength Comfort – Features RockJock Johnny Joints on the adjustable ends for articulation and tapered polyurethane bushings on the fixed ends for a quieter, more controlled ride with reduced NVH (noise, vibration, and harshness).
  • Precision Adjustability for Complete Suspension Control – Provides caster correction, pinion angle tuning, and axle centering, significantly improving handling and steering response.
  • Eliminates Steering Instability Enhances Ride Quality – Reduces wandering, bump steer, and poor steering return, creating a more stable and predictable driving experience.

Optional Inward Bend for Larger Tires

Available as an upgrade to provide extra tire clearance, ideal for trucks running larger tires that may rub against factory control arms.

Recommended Pairing

Adjustable Front Track Bar (D-35-2003-FTB1) – For full front-end control and axle alignment, we recommend adding the Adjustable Front Track Bar, which enhances steering precision and suspension geometry.

A Complete Solution for Improved Front-End Performance

Lifting or modifying your Dodge Ram 3500 can cause caster misalignment, axle shift, and reduced steering precision. The Trail Series Adjustable Front Suspension Kit corrects these issues, ensuring proper suspension geometry, smoother handling, and long-term durability. Whether for daily driving, off-road use, or heavy hauling, this kit provides substantial improvements in stability and control.

Optional Hardware Upgrade

This set installs using factory hardware, but for increased durability and proper alignment retention, we offer an optional Grade 8 hardware kit with a cam bolt delete, available separately. This upgrade eliminates weak factory cam bolts, ensuring better alignment stability and preventing unwanted shifting under heavy loads.

Highly Durable Two-Stage Powder Coating

Each component undergoes a two-stage powder coating process for superior durability. A zinc primer base coat provides advanced corrosion resistance, while the durable topcoat is available in 10 colors to match your build and style.

Proudly Made in the USA

All components are designed, manufactured, and tested in Orem, UT, ensuring top-tier craftsmanship and strict quality control while supporting American manufacturing.

Final Thoughts

The Trail Series Adjustable Front Suspension Kit is an essential upgrade for Dodge Ram 3500 owners looking to correct alignment, enhance control, and eliminate steering issues. Built for strength, adjustability, and reliability, this kit ensures optimized suspension performance for both on-road and off-road conditions. Upgrade today and experience the difference in stability and handling!

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.

Great experience with Core 4x4! I purchased some suspension parts for my dad's 98 Jeep TJ. The products they make are super durable and look even better in person. Attention to detail and overall superior quality. The staff at Core 4x4 is super helpful also, Korby has been great. Updating me on the status of my order and sending me tracking numbers as well. Thank you all at Core 4x4, keep up the amazing work!

Had a great experience with Core 4x4, I desperately needed a custom track bar and found out just a couple days before Easter Jeep Safari. Spence was a huge help and made it happen with plenty of time to spare. Their parts are top notch!

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)

I bought the 16pc Cruise Series Adjustable Control Arm, Track Bar, Steering, End Link Kit to replace a worn budget 4" lift on my used JKU. These are top quality parts; very solid. Customer service is unsurpassed. They even matched prices on my order placed before the tax day sale. I made an error in ordering a drag link flip kit; they were quick to help me fix this too. There's peace of mind knowing these components are made in the USA. Thank you. 👍👍

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!

Absolutely incredible family owned business. I asked to pick up my order since I’m local and they came in on a weekend to accommodate. Had to make some adjustments to parts and took the time to make sure it was perfect. Parts are incredible quality. If you have a Jeep, do not hesitate to support this local business.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.
