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

Take full control of your Dodge Ram 2500 (2003–2007) with the Tow Series Adjustable Front Suspension Kit—a massive upgrade engineered specifically for towing, hauling, and extreme-duty applications. Factory suspension components simply can’t handle the added strain of heavy loads, leading to death wobble, wandering steering, and premature wear. This kit eliminates these issues by delivering unmatched strength, precision alignment, and rock-solid stability, making it an essential upgrade for any Ram owner who demands performance and reliability.

What’s Included in the Kit?

  • Adjustable Front Upper Control Arms (TOW-D-25-2003-FU2)
  • Adjustable Front Lower Control Arms (TOW-D-25-2003-FL2)
  • Tow Series Adjustable Front Track Bar (D-25-2003-FTB1)

Key Features Benefits

  • Eliminates Death Wobble Wandering Steering – By correcting caster and axle positioning, this kit locks in front-end stability, ensuring precise steering even under heavy towing loads.
  • Maximum Strength for Towing Hauling – Built from 1.75” OD DOM Tubing with a 5/16” wall thickness, these components outperform factory parts by a wide margin, preventing bending, flexing, or failure under extreme conditions.
  • Fully Adjustable for Perfect Alignment – Featuring left- and right-hand threads, all components can be adjusted on the truck without removal, making it easy to dial in precise caster and axle centering for improved handling and tire wear.
  • Extreme Durability with Rock Jock 4x4 Johnny Joints – Unlike factory-style rubber or poly bushings that degrade under load, these greaseable, fully rebuildable Johnny Joints provide exceptional longevity, reduce wear on surrounding components, and eliminate bushing deflection for consistent performance.

Optional Inward Bend for Larger Tires

Running oversized tires? The optional inward bend upgrade allows for greater tire clearance, eliminating rubbing against control arms. This is a highly recommended upgrade for anyone experiencing steering limitations due to larger tires.

Two-Stage Powder Coating for Maximum Protection

Every component undergoes a two-stage powder coating process for exceptional durability and corrosion resistance. A zinc primer base coat ensures advanced rust protection, while a durable topcoat, available in 10 color options, allows you to match your truck’s style.

Made in the USA

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

Optional Hardware Upgrade with Cam Bolt Delete Kit

This kit 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-25-2003-K5) is a game-changing upgrade for Ram 2500 owners who demand stability, durability, and performance. Whether you're hauling heavy loads, towing trailers, or tackling rough job sites, this kit delivers the control and strength you need to eliminate front-end issues and drive with confidence. Upgrade today and experience the difference in handling, stability, 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.

Korby was extremely helpful in helping me find the right part for my truck. He was kind, knowledgeable, and patient while I asked a million questions. He also went out of his way to find the right shipping option for me since it’s tricky where I live. I’m looking forward to getting the parts so I can fix my truck and go adventuring again soon!

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!!!!

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! 👍👍

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.

Excellent quality product and service. My l lower control arms broke and within the same day core 4x4 hooked me up with tier 2 arms and with the color I wanted. My Jeep rides better and has been solid for several months so far. 10/10 would recommend their products to anyone.

I broke a grease fitting off in my end link. I thought I was going to have to buy a new one. Reached out to Core 4x4 and wham! bam! They fixed it and sent it back with 2 day shipping. Got it a day early even. If they couldn't fix it they were going to send me a new one. Now that's customer service! They are now a permanent part of my garage. Thank you Core 4x4!
