New for the 2019-2020 Chevy/GMC 1500 trucks, Zone Offroad has released adventure series upper control arm (UCA) kits specially designed for improved suspension travel and added strength over the factory units; perfect for leveled/lifted applications. They use a repositioned ball joint mount to provide greater range of motion for increased suspension travel. This corrects the ball joint binding issue common on stock control arms that may lead to premature wear of factory ball joints. Specially built to maximize tire/wheel clearance, these steel fabricated, fully boxed, and welded with CNC machined ends, arms feature high quality greaseable ball joints and OE rubber bushings to strength, durability and quiet operation. The high quality ball joints are build to outperform OE units allow for easy servicing and superior corrosion protection when compared to uniball style control arms. Red anodized aluminum ball joint caps are used to keep mud and grime off the ball joints and create a clean, high-end appearance. At the frame mount, the arms use factory style, durometer-specific rubber bushings pre-installed for quiet maintenance free operation. This kit includes hardware to mount the factory brake line brackets to the new arms and optional weld-in steering stops to allow use of more tire/wheel combinations. These UCA's come finished in a durable textured black powercoat for long-lasting good looks. Arms are fully assembled for quick, easy installation right out of the box. In addition to the arms, optional weld-on steering stops are supplied for trucks using factory wheels, as well as a wheel spacer for clearance in the event the factory spare tire needs to be installed. Upgrade your GM's upper control arms to Adventure Series Upper Control Arms from Zone Offroad.

The steering stops are not required for use with factory wheels, but they are recommended to for clearance when turning full lock

I just purchased a 2020 GMC AT4. I am going to purchase your 1.75″ Leveling Kit but on the fence post if I really need these really nice Upper Control Arms. Is the 1.75″ leveling kit not good enough by itself ($130) or are there issues with just using the leveling kit? One of the other companies product has a warning about the leveling kit and using the 4WD Auto function on the truck. Does Zone have any warning associated to the vehicles drive line from installing the leveling kits with/without the Upper Control Arms? Asking lots of questions to make sure I don’t ruin other components on my truck by not purchasing the right parts to level it. Thanks Tony

Hey Tony,
Thanks for your interest in Zone Offroad. Short answer is no, the UCAs are not required to run our leveling kit on the AT4, but are a good upgrade and have a few benefits over the factory UCAs.

The AT4 uses the same base chassis/suspension design as the standard GM1500 trucks, just with roughly a 2″ taller ride height. In general adding a leveling kit would be like setting the ride height of a standard GM1500 3.5-4″ over stock which if not handled correctly can cause issues. The warning that other kit use is due to most using a top mount spacer design which will give the ride height, but also increases the overall length of the strut assembly to the point of can overextending the suspension, steering and driveline angles at full droop. In contrast, our leveling kit is designed a bit differently. For one the overall ride height is only 1.75″ as that is what is needed to level out the AT4. Secondly our kit uses a combination of a smaller top mount + preload spacer. The preload spacer won’t increase the overall length of the strut assembly so our smaller top mount spacer keeps the strut assembly within an acceptable length to allow full suspension travel, while retaining the factory ride quality without causing premature wear of front end components.

As far as benefits to upgrading our UCAs in combination with our leveling kit:
– Improved strength over the factory UCAs
– Improved travel/ball joint positioning (uses an indexed ball joint cup – will help with camber adjustments)
– Uses a high strength ball joint for improved durability
– Its serviceable (greaseable) for a long life and quiet operation
– Improved appearance overthe factory UCAs
