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.

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

I have a 2016 RAM 1500 Crew Cab and I replaced the rear upper and lower control arms also the pan hard track bar and also the sway bar and links for the rear with all I had the articulating bushings. The vehicle now has no body role. They are absolutely incredible if you get the control arms you gotta get the CORE 4 x 4sway bar end links don’t don’t try and be cheap and get Moog or something else you got to get articulating bushings get the core 4 x 4 ones they are the best. My truck drives now through the canyons like a BMW. I have Fox high-performance shocks on there as well with all the CORE 4 x 4 suspension parts and they are amazing. Well worth the money I would highly recommend anybody thinking about CORE 4 x 4 go with CORE 4X4 and if you can go with their articulating bushings, they’re unbelievable drives better now than my Escalades. Well planted no body role and smooth on the Highway unbelievable the difference they all made!! THANKS AGAIN CORE 4x4!!!!

To start off if you're looking to upgrade your control arms definitely hit this company up. Great product, easy install of the product, with three different tiers everything is priced pretty good, I'm a sticker guy and they sent a sticker for each arm each track bar and also three extra ones so the extra are on the Jeep the advertise them for sure. If you're reading this review I highly recommend you to check their website out.

Exceptional customer service. All my questions were asked in a timely manner and parts were replaced when an error occured. I encourage people to make purchases due to their exceptional quality products, but also because of their customer service. Will make additional purchases in the future.

Installed rear and upper control arms and track bar on my 3rd Gen 4RUNNER to align rear axle and restore factory wheel base after 3.5" lift. Car drives better than New! Improved handling cornering and overall driving. Very solid and high quality made product. Support is outstanding. Shipping extremely fast. Thank you so much. I wish you will have something new for my car.

Outstanding experience! I asked Core to build me a set of custom control arms that were larger/heavier than they normally build. They gladly accepted the challenge and turned out an expertly crafted and super strong product ahead of schedule. Fit and finish are excellent. Spence and Cameron were a pleasure to work with every step of the way. And all of this for a very reasonable price. I highly recommend these guys!

I meant to put this reviewing about a year ago now, but ever since I’ve had the core 4 x 4, upper and lower control arms on my 2017 ram 1500, they have worked flawlessly leave been on many offering chips, and I’ll definitely be buying new accessories from them in the future and their new upper control arms that they’re offering for all of the ram trucks. Fantastic customer service fantastic health very automotive, off-road, friendly, and any aftermarket thing for your truck or SUV that they currently have!

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.
