Regain Control. Restore Geometry.
Upgrade Your Suspension.

If you’ve lifted your truck, your factory upper control arms (UCAs) are now working against you. Lifting disrupts suspension geometry, leading to poor alignment, premature tire wear, and degraded handling.

RRW Forged UCAs are engineered to fix that.

Aerospace-grade strength with lightweight performance

Optimized for lifted geometry

Bolt-On Install

Compatible with stock & aftermarket coilovers

COMPLETELY SEALED UNIBALL

Our billet UCA features an entirely sealed uniball, which extends the lifespan of the fastest-wearing component. Ensuring that the Kevlar-reinforced PTFE liner remains free from debris and grime is essential for its longevity.

CAD DESIGNED & FEA ANALYZED

Using 3D scan data, we reverse engineer the geometry and optimize it for lift. This optimized geometry creates balanced comfort and performance both on and off road. Several prototypes are made, fitted, and analyzed to ensure correction of camber, caster, reduce bump steer.

frequently asked questions

Factory upper control arms weren’t built for aggressive off-road travel. RRW's UCA fix alignment issues, reduce stress on ball joints, and gives you the confidence to send it hard — and land it clean.
built to correct camber/caster on lifted trucks for smoother handling and tire wear
increases articulation for improved off-road traction and comfort
reduces bind and improves ride feel across all terrain

Yes, we sell replacement rubber boots here.

Ball joints are what factory UCA are equipped with and, while quiet and comfortable, they are not durable for offroad use and tend to wear prematurely.
Conversely, uniballs, especially the large 1.25 or 1.5 inch ones that we use, are far superior in terms of durability and range of motion. Although uniballs are known to be noisy when dirt and debris begin wearing out the PTFE liner, our rubber dust boot completely seals the uniball away from these elements. This not only prevents noise, it also potentially extends the life of the uniball allowing it to outlast a standard ball joint.

At this time, we only ship to the contiguous US States, Hawaii and Canada. For shipping inquiries outside of those regions, please reach out to our dealers Custom Offsets and Trail Built.

Good quality rim that's light weight

Good quality rim. Main thing I was after was the -25 offset and the weight savings. Everything seems to be good. I'm currently running the monoforge 2 without the rings and instantly noticed the weight savings of the wheel when driving. Truck feels more responsive while turning and has better acceleration and braking than the old SCS wheels.

RR7-H Monoforged 2.0 Hybrid Beadlock Wheel | MATTE BRONZE

Good quality, lots of bite.

Lug nuts seem to be of good quality with quality coating. They are deep, I counted 12-14 full turns on each as they were installed. Should last for a long time with plenty of bite.
