Upgrading the UCA (upper control arm) is a must when leveling or lifting your front end by 2-3”. Our meticulously designed UCA's correct your geometry for the ultimate ride.

Specifications

Uniball (PTFE Kevlar reinforced) bearing completely sealed for long service life
Designed to maintain proper wheel alignment for 1.5in - 3in lift to prevent tire wear
Custom-plated 14mm uniball through-bolt (equal in strength to a 12-point bolt) safely clamps the entire outboard bearing assembly directly to the upright - less chance of failure than 2-piece designs
Allows full lock-to-lock tire clearance throughout the suspension travel
Each inner rod-end has two bolts per side clamp for safety
Each rod-end bolt has a nylock nut - no threaded holes to strip
The inner rod-end clamps are fully radiuses inside and out - which means no sharp corners that might cause stress cracks
FEA analyzed for 10,000-pound side impact loads
Finished in Type II Anodize

Product Highlights

American made
CNC precision machined and anodized in California

Aerospace grade material
Crafted from aerospace 6061-T6 Aluminum

Completely sealed uniball
Only we offer a billet UCA that fully seals the uniball, prolonging the life of the fastest wearing component. By keeping kevlar reinforcement PTFE liner free of debris and grime, its life is prolonged.

CAD Designed and FEA Analyzed
Using 3D scan data, we are able to reverse engineer the geometry and optimize it for lift. The geometry is configured for balanced comfort and performance both on and off road. Various versions of prototypes are made, installed, and analyzed to ensure correction of camber, caster and reduced bump steer.

Machining Details
Large chamfer at inner radius increases clearance for the coil spring at full suspension droop.

frequently asked questions

Yes, aftermarket lug nuts with a conical seat will need to be purchased separately. OEM lug nuts will not work.

OEM TPMS will work - the shop that installs your wheels should have an adapter available.

Yes, hybrid wheels can be used as is, without rings. Rings are not mandatory. If you later decide to add rings, you won't need to rebalance your wheels.

Yes, all of our wheels are street legal and DOT approved. The beadlock ring and mounting the wheel/tire as a beadlock is for offroad use only.

Yes, our wheels are hub-centric for most trucks (Tacoma, 4Runner, GX, 2nd Gen Tundra, F150, Colorado, Wrangler and Gladiator). For all other trucks, refer to our FAQ page for recommended hub ring sizes.

Yes, all wheels include ABS center caps. Billet caps are also offered as an upgrade and will work with all wheels.

Opt for the ring that you will use for its intended purpose. The primary function of the beadlock ring is to clamp the tire bead, which will leave a gap between the wheel and ring when not installed as designed.

It depends on setup. Is your truck lifted or stock height? Stock height trucks are best suited for +0 offset. The more negative the offset, the more the wheels will poke out past the fenders.

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.

I've never received more compliments on a wheel than I have with these. When it came to finding new wheels for my LC I knew right where to go. Even the guys at the tire shop were snapping pics. Customer service is also great, and shipping is quick

RG6-H Hybrid MonoForged Wheel | MATTE BRONZE

Abs center caps and wheel lip bolts.

Bought these for some discontinued rrw wheels. Caps are nice but the mounting bolts are larger diameter than the old ones. Wheel lip bolts are nice but the finish is not the same gold color as the discontinued wheels. Not a big deal just wanted to let others know if they have older wheels it will not be the same. I'm just going to find smaller threaded bolts for the caps and spray paint the lip bolts to match the old ones. I went with the abs caps due to other reviews saying the aluminum ones color fades out. Hope this helps anyone with older wheels.

Embossed ABS Center Cap (New)

Amazing wheels

These wheels are beautiful and strong. The color is perfect for my truck and along with some Toyo’s balanced very well. Perfect fitment and poke for the 3rd gen Tundra!

RS5-H Hybrid MonoForged Wheel | MATTE BRONZE

Love these wheels

Some of the best bang for the buck as far as aftermarket wheels for the F-150 Raptor goes. I shopped wheels for months, looking at all the major brands as far as some smaller brands' offerings. I compared weights, offsets, everything. I kept coming back to these RR7-H Flow Form wheels. They offered the best best features at their price point. The only wheels I liked better were almost twice if not more than twice the price of these wheels. FYSA, I weighed one wheel on my home scale at 23.6 lbs! That is as light or lighter than some forged wheels at this size. I can't recommend these wheels enough. They also look WAY better than the stock Raptor wheels. If I could change one thing, I do wish there were less aggressive offsets available, but that really isn't specific to just RRW, most wheels that I liked the looks of were only available in +0 offset.
