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.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (TOW-D-35-2003-FU2)
  • Adjustable Front Lower Control Arms (TOW-D-35-2003-FL2)
  • Adjustable Front Track Bar (D-35-2003-FTB1)

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!

Great company, who worked with me on shipping parts to arrive in time for a show. When I explained my concern they went above and beyond to make it happen. Quality of the parts is top notch.

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.

Best control arms I have installed on any of my builds. After running every major manufacturer, Core 4x4 is on par or better than all the high-end companies at a fraction of the cost. Lifetime warranty is the cherry on top.

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.

Solid product, the lifetime warranty sealed the deal for me. Installed on my TJ and the ride quality improved noticeably. Shipping took a bit longer than expected but the parts were worth the wait.

Core 4x4 has no issues standing behind their already amazing products and will quickly and professionally solve issues may they arise. I will continue to be a customer.

2022 I ordered a 2023 Jeep Wrangler Rubicon in High Velocity yellow. Without any hesitation I knew I was going with Core 4x4’s 16pc Camp series suspension, powder coated in yellow. Compliments were a given from any and everyone that looked under my jeep. So beefy, I may have left some yellow paint on the rocks from Maine to Florida, but no bends or breaks. Customer service has been perfect each and every time I have needed something. Their warranty is top notch! Their communication is also wonderful. Might upgrade to the Crawl Series control arms where the Johnny joints are on both sides. Great all around company and a great team to troubleshoot your issue and come to a conclusion. Nothing bad to say about this company. Just love this suspension.

Korby and the rest of the team at Core 4x4 know there stuff and answered my question in a timely manner. They even were able to quick ship a re-build kit for me so I could get my truck back on the road- Thanks!

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.
