Why Builders Choose CORE 4X4

Warranty facts, not marketing language.

vs. MetalCloak

Their “lifetime” language refers to their service model. Actual parts warranty: 1 year. Ours: lifetime.

vs. Teraflex

Skip a maintenance interval? Their warranty voids. Ours doesn’t.

vs. Clayton Off Road

Clayton warrants their Johnny Joints for 90 days. We cover ours for life.

Enhanced Suspension Control for a Smoother, More Stable Ride

Upgrade your Dodge Ram 3500 (2003–2007) with Town Series Adjustable Front Lower Control Arms, engineered to provide improved caster correction, precise wheelbase re-centering, and enhanced ride quality. Designed for small lifts and leveling kits, these arms help restore proper alignment, reducing steering wander, poor return-to-center, and excessive tire wear. If your truck has a lift greater than 3 inches, pairing these with our adjustable front upper control arms will ensure full control over caster and wheel positioning.

What’s Included in the Set?

  • Town Series Adjustable Front Lower Control Arms (TWN-D-35-2003-FL2)

Key Features Benefits

  • Heavy-Duty 1 7/8” Steel Tubing Construction – Built from high-strength steel tubing, delivering superior strength, durability, and reliability over factory components.
  • Tapered Polyurethane Bushings for Maximum Comfort – Both ends feature greaseable, rebuildable polyurethane bushings, significantly reducing NVH (noise, vibration, and harshness) while improving handling and ride comfort.
  • Precision Adjustability for Optimized Suspension Geometry – Corrects caster, pinion angle, and wheel centering, restoring proper suspension function for leveled trucks and small lifts.
  • Eliminates Steering Instability Improves Drivability – Helps reduce wandering, improve return-to-center steering, and prevent excessive tire wear, especially important for towing and daily driving.
  • Recommended Pairing for Lifts Above 3 Inches – Town Series Front Upper Control Arms (TWN-D-35-2003-FU2) – For full caster correction and axle positioning on trucks lifted over 3 inches, we recommend upgrading both the upper and lower control arms.

A Complete Solution for Improved Ride Quality

Factory control arms often fall short when adjusting for ride height changes, leading to misalignment, steering instability, and excessive tire wear. The Town Series Front Lower Control Arms address these concerns by providing improved axle positioning and ride stability, particularly for leveled and mildly lifted trucks. If your truck has a lift over 3 inches, upgrading to adjustable upper control arms will further refine caster correction and suspension performance.

Optional Hardware Upgrade

This set installs using factory hardware, but for enhanced alignment stability and durability, we offer an optional Grade 8 hardware kit with a cam bolt delete, available separately. This upgrade eliminates weak factory cam bolts, ensuring stronger alignment retention and preventing unwanted shifting under load.

Highly Durable Two-Stage Powder Coating

To withstand the harshest conditions, our control arms undergo a two-stage powder coating process: Zinc primer base coat for advanced corrosion resistance. Durable topcoat available in 10 colors to match your truck’s style.

Proudly Made in the USA

All CORE 4X4 components are manufactured in Orem, UT, ensuring strict quality control and superior craftsmanship while supporting American manufacturing.

Final Thoughts

The Town Series Adjustable Front Lower Control Arms provide critical improvements to drivability, alignment, and handling, making them a must-have for leveled trucks and small lifts. If your lift exceeds 3 inches, pairing them with adjustable upper control arms will ensure full caster correction and axle control. Upgrade today for superior ride quality and long-term suspension durability!

Select your lift size in Step 1 — the kit ships with the correct geometry for that height. If you’re running a non-standard setup, call us before ordering and we’ll confirm compatibility.

Death wobble is a geometry problem, not just worn parts. Cruise Series corrects caster angle and eliminates the flex points that let shimmy start. Replacing one part at a time delays the fix — this replaces the geometry.

Yes, if you’ve done a lift kit before. Full-day project. Watch the complete JT install walkthrough on our YouTube channel — most owners wrap it in a day. Any off-road shop can run it if you’d rather have it done.

Any non-wear component fails — we replace it. No mileage cap. No maintenance intervals to track. No fine print about voiding if you miss a service. Lifetime means lifetime.

Teraflex’s lifetime warranty voids if you miss a maintenance interval. MetalCloak’s actual parts warranty is 12 months — their “lifetime” language refers to their service program. No conditions here.

We have all shopped places where the person on the phone makes you feel like they don't have the time to talk to you the customer or answer your questions. I can tell you first hand that's not Core 4x4. They have the best customer service I have seen so far. They have taken the time to respond to all of my questions in a very prompt and professional manner, taking the time to answer each and every question I have had. Lets put it this way if Core 4x4 sells a product I am wanting for my truck I will buy it from them, I highly recommend Core 4x4.

Good company, they offer well built parts and Great customer service. I had a couple of hang ups with my control arms that I purchased, they were very easy to work with and found the solution to make them work.

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!

I couldn't have been more excited for the initial unboxing of these new Core 4x4 UCA's! They appear to be so well built and just a true quality product. Installation was a breeze and the initial testing with the forklift appears to have given me some additional flex with less binding on the rest of the components now that the geometry is back properly aligned. Time will tell how they hold up on my near future off-road adventures but I don't have any doubt that they are up to the task!

The folks at Core 4X4 are always wonderful to deal with. They explain your options and never pressure or rush things. The quality of the Core Control Arms is top shelf, especially if your goal is to stop wheel hop. I recommend Core 4x4 without reservation ! ! !
