Product Details

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.

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.

Built for strength, adjustability, and reliability, this kit ensures optimized suspension performance for both on-road and off-road conditions.

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. 👍👍

I purchased a set of the Cruiser Series control arms for my Jeep Jk based on postive reviews from different Jeep Facebook pages. Ordered and 2 days later realized they had the very same exact arms on sale in the overstock section. Called them up and they refunded me the savings from my original purchase. Amazing, honest service. Can't wait to get them installed. Keep up the good work guys.

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.

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!

These guys are great. You can get them on the phone for support. This important and is not always the case with other custom parts builders. Their control arms are bomb proof and offer plenty of options. You can get real genuine Currie Johnny joints without paying the price for Currie arms.
