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.

I want to share a truly positive experience. I ordered a car kit consisting of two packages, but unfortunately one was lost during shipping with UPS. The situation could have become complicated... but it didn't. The company manager was extremely helpful and professional: he personally followed up on the situation and did everything he could to resolve the issue, even sending me the package again without hesitation. It's rare to find such attentive and reliable customer service these days. My sincere congratulations on your professionalism and commitment: that makes all the difference.

Every product I have received from them has been nothing short of fantastic. Korby in Customer service went above and beyond to help me fix my own mistake. I cannot reccomend them enough.

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.

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.

Top notch company. Mechanic lost bolts that clamp upper control arms. Korby sent out spare bolts no charge. Best customer service I’ve come across in a long time. Only suspension brand I’ll ever use.

After ordering an upper and lower adjustable control arm kit manufactured by CORE 4X4 from a jeep parts distributor who's intials are E.T., they came with 3 of the threaded ends missing. After over 2 months of phone calls and emails to this E.T. company nothing was resolved. I finally decided to call CORE 4X4 myself and tell them my dilemma. I spoke with a very personable and professional gentleman named Korby, who is one of CORE 4X4's representatives, after a brief discussion of what I went thru he simply asked me for a picture and some measurements and the items I was missing and asked if I could cover ONLY the cost of shipping and I had my missing parts in exactly 1 weeks time. This company not only builds all it's parts in the U.S.A., they stand behind their products with great customer service and life time warranty. My experience with this company and their Rep Korby was fantastic. I would definitely recommend CORE 4X4 to anyone who needs parts for any 4x4 projects. You just can't beat their quality and service.

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

First off: Korby, the gentleman that helped me decide on which kit to go with is EASILY the nicest, and most patient person I’ve dealt with, when ordering parts for this build. Second: the quality of the product is INSANE! These parts are so nicely fabricated, then powder coated for extra longevity, and they even offer an aluminum upgrade in some cases (which I went with, to save weight). Having said all of this, the most impressive thing was the lead time. These parts are build to order, and I literally ordered my suspension one week ago, today! Yes, they built, powder coated, packaged, shipped my suspension components (RAM 1500 Track rear trailing arm full set in 7075 aluminum, and front upper control arms), AND they arrived, all within a week! Granted, that I’m only one state away, but WOW!!! One week?! Amazing! So, in sort: excellent products, which arrived excellently packaged (no damage, an boxes not over-stuffed with heavy suspension parts; three boxes total, as opposed to one super heavy one…my back thanks you), super quickly, and customer service that ANY business would be envious of….so, if you’re in the market, absolutely go with 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.

Finally a company with a great product and customer service to match. I changed my order last minute from short arms to long arms. The lift is extremely well built. Korbey was awesome! Highly recommend Core 4x4
