Complete Front-End Suspension Upgrade for Strength, Stability Control

Upgrade the front suspension of your Dodge Ram 2500 (2003–2007) with the Trail Series Adjustable Front Suspension Kit. Designed to improve caster, enhance axle positioning, and eliminate steering instability, this kit is a major improvement over stock components. Whether you're hauling, towing, or navigating rough terrain, these adjustable control arms provide the strength and adjustability needed for maximum suspension performance.

Key Features Benefits

  • Heavy-Duty DOM Tubing Construction – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, ensuring superior strength and durability for demanding applications.
  • Hybrid Joint Design for Strength Comfort – Equipped with RockJock Johnny Joints on the adjustable ends for articulation and tapered polyurethane bushings on the fixed ends for a smooth, quiet 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-25-2003-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 2500 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 the 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.

First time buying from Korby @ Core 4x4 and it’s being nothing short of a great experience. I bought the non adjustable Trail kit for my 5th Gen Ram 1500 with a 2” lift. The welds look great, nice powder coat finish and quality bushing. Had some trouble fitting the grease nipples due to the powder coating but a thread tap would fix that. They fit easily and perform great. I felt the improvement straight away. No more wheel hop on hard acceleration which was my main reason for the purchase. I was missing some smaller bushings needed for the 5th Gen and Korby’s custom service was on point, with responsive emails and mailing out the missing parts straight away. Very happy with their products and customer service. Highly recommended company👌🏽

Small business, family owned, made in the USA, lifetime warranty. Purchased Tier 3 control arms and rear track bar for a 2006 Jeep LJ. Simple website and easy to contact over phone and email. I had some technical questions and they were happy to answer them. They allow local pickup and were built to order same week. The order was wrapped and ready when I walked in and even gave a tour of the shop. They abrasive blast all raw materials to achieve a better surface profile for powdercoat to adhere and create a smooth, durable finish. I also noticed several CNC machines and a robotic welder they use for all their parts. A small outfit with a robotic welder? Their concern for quality is obvious and it shows in the parts they make. Very impressed. Happy to do business with these guys.

I purchased upper and lower adjustable arms for my WJ and lowers were missing the spacers. I didn't know until 3 months later when I was installing them. With absolutely zero hassles they quickly sent me the missing spacers. Fantastic product and service! Huge thank you guys for the awesome service and parts!!! Customer service is quickly becoming a lost commodity and you guys gave me hope that it's still alive and well, you just have to buy from the right people... Thanks again for going above and beyond! 👍👍

Recieved warrenty exchanges for my control arms last night couldnt be happier!!! Lets talk about the arms tho! Great quality arms in multiple styles and colors!!! I purchased the teir 3 short arns for my 98 xj. I can say that they setoff nicely so my 35 inch tires do not rub! As long as you can get a photo or video of broken hardware core will take care of you. The body of the arm is bulletproof. However make sure to maintain and grease the joints regularly as with any greaseable joint and they shouldkast forever. I had a few problems arise a year after purchase and after some troubleshooting spence was able to help get me the correct parts to get back on the road. I recommend this setup to any and all jeepers looking to get away from the stock arm setup. Alltogether i am Very happy with the performace of my control arms!!!! Mechanic and bodyman of 12 years and my first choice for quality control arms!!

First off, I wish I knew about them sooner. The customer service is top tier. The response time is about 30 min no waiting 1-3 days to get a response. The parts are heavy-duty and look amazing. The packaging is perfect, I can't wait to hit some trails. Thanks Core4x4

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.

Great customer service. I got my front upper and lower control arms and hardware on Friday afternoon. It didn’t come with instructions so I called Core 4X4 and they immediately e mailed me the instructions. Also, the kit I got had the spacers missing so I called. It was late Friday by thus time but they took care of the issue first thing Monday morning and I got the spacers on Tuesday. Great company.
