The Ultimate Front-End Upgrade for Heavy-Duty Towing Hauling

Maximize the performance of your Dodge Ram 3500 (2003–2007) with the Tow Series Adjustable Front Suspension Kit—a must-have upgrade engineered for towing, hauling, and extreme-duty applications. Stock suspension components struggle under heavy loads, leading to death wobble, wandering steering, and premature wear. This kit eliminates those issues by delivering increased strength, precision alignment, and rock-solid stability, ensuring superior control and durability under demanding conditions.

Key Features Benefits

  • Eliminates Death Wobble Wandering Steering – Corrects caster and axle positioning, ensuring precise steering and eliminating common front-end issues associated with heavy towing and hauling.
  • Maximum Strength for Heavy-Duty Applications – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these control arms are designed to withstand high-load stress without bending or flexing.
  • Fully Adjustable for Precision Alignment – Designed with left- and right-hand threads, all components allow for on-the-truck adjustments without removal, ensuring caster and axle centering for optimal handling and tire wear.
  • Unmatched Durability with Rock Jock 4x4 Johnny Joints – Featuring greaseable, fully rebuildable Johnny Joints, these components reduce wear, eliminate bushing deflection, and provide long-term reliability in the toughest conditions.

Optional Inward Bend for Larger Tires

Running oversized tires? The optional inward bend upgrade provides extra clearance, preventing rubbing on the control arms. This is highly recommended for those running larger-than-stock tires to maintain full steering articulation.

Two-Stage Powder Coating for Maximum Protection

Each component undergoes a two-stage powder coating process to ensure long-lasting durability and corrosion resistance. A zinc primer base coat provides superior rust prevention, while a durable topcoat, available in 10 color options, allows you to match your truck’s build.

Made in the USA

Manufactured in Orem, UT, the Tow Series Front Suspension Kit is proudly built in the USA, ensuring top-tier craftsmanship, strict quality control, and unmatched reliability.

Optional Hardware Upgrade with Cam Bolt Delete Kit

This set installs using factory hardware, but for enhanced durability and easier installation, we offer an optional Grade 8 hardware kit with a cam bolt delete kit, available separately. The cam bolt delete kit eliminates weak factory cam bolts, preventing unwanted alignment shifts under load. It locks in proper alignment, ensuring stable, consistent performance under heavy towing and hauling conditions.

Final Thoughts

The Tow Series Adjustable Front Suspension Kit (TOW-D-35-2003-K5) is the ultimate upgrade for Ram 3500 owners who demand exceptional strength, precise alignment, and long-term durability. Whether you’re hauling trailers, towing heavy loads, or navigating demanding job sites, this kit provides the control and stability needed to tackle any challenge with confidence. Upgrade today and take full control of your Ram 3500’s suspension for unmatched performance and reliability!

Ordered a set of Core 4x4 control arms for my 2006 Jeep TJ. These are some heavy duty quality control arms. Can't wait to get them installed. Great customer service too!

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!

Great Experience. I wanted to make changes to my order and Korby was more than willing to work with me to get everything corrected. Hope to deal with these guys again in the future.

I have nothing but good things to say about Core 4x4. I have the crawler series on my JKU and we take it all over the place. These parts handle everything we throw at them.

I recently ordered a set of control arms from Core 4x4, and the entire experience was absolutely top-notch from start to finish. The ordering process was smooth, the parts arrived quickly, and the control arms themselves are extremely high quality—solid construction, great finish, and clearly built to last. I also want to give a special shout-out to Korby, the guy I spoke with during the process. His customer service was amazing. He went above and beyond to make sure I got exactly what I needed, answered all my questions, and made the whole experience stress-free. You don’t see service like that very often these days. If you’re looking for high-quality suspension components backed by truly exceptional customer service, I highly recommend Core 4x4. I’ll definitely be buying from them again.

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.
