F-150 Upper A-Arms: UMI Performance Adjustable Lowered Kit

Truck builds are coming back around in a big way. For a long stretch, the lowered street truck scene felt like it belonged to the 70s and 80s C10 crowd. Now the late-model platforms are catching the same energy. The 2015-2025 Ford F-150 sits right at the center of that movement. Aluminum body, wide aftermarket support, and a chassis that responds well to a proper drop, which is where the UMI Performance F-150 upper A-arms come in.

The problem has always been the same problem every lowered truck owner runs into. When you lower a late-model F-150 without addressing the upper control arms, the front end suffers in real ways. The factory upper A-arms cannot correct the camber change that comes with the drop, which means your alignment shop runs out of adjustment before the truck hits spec. That is the exact gap the UMI F-150 upper A-arms fill.

The UMI F-150 upper A-arms just landed to solve that problem. Part number 6565 is the kit, and UMI engineered it specifically for trucks running 2.5 inches of lowering or more, with the sweet spot in the 3 to 6 inch range. That covers the bulk of street builds we see in the wild.

What Makes The UMI F-150 Upper A-Arms Different?

UMI machines these arms from premium US steel and TIG welds every joint. The Cerakote finish handles abuse, and you get a choice of red or black. The standout feature lives at the ball joint. UMI laser-cut and fully welded a heavy-duty adjustable ball joint pad into each arm. That pad lets you set camber in clean increments instead of fighting alignment shims.

UMI built the 6565 kit specifically for trucks running 2.5 inches of lowering or more, with the sweet spot in the 3 to 6 inch range. That covers the bulk of street builds we see in the wild, from mild drops to full slammed daily drivers working the show circuit.

How The Adjustable Camber Pad Works

The adjustable ball joint pad is the heart of this design. Therefore, your alignment shop can hit factory caster and camber spec without stacking shims behind the cross-shaft. As a result, tire wear evens out, and the truck tracks straight. UMI also engineered the ball joint pocket so the joint itself bolts in and out. Since standard parts-store ball joints fit the pocket, replacement down the road costs you almost nothing.

For instance, a 4-inch drop on stock arms locks you into roughly 2 to 3 degrees of negative camber. With the 6565 kit, you dial it back to factory spec or run a touch of negative for sharper turn-in. The call is yours.

Why The Bushing Design Matters

UMI runs greasable Delrin bushings on the 6565 kit. Delrin is a low-friction polymer that handles street and track abuse without binding. Each bushing rides inside a flanged two-piece sleeve machined from billet steel and zinc-coated for corrosion resistance. The flanged design keeps grit out of the bushing area, so the arms stay smooth thousands of miles down the road.

Rubber stock bushings deflect under load. Delrin does not. That means cleaner steering response and tighter feedback through the wheel, especially when you push the truck into a corner with any weight on the nose.

Why Cerakote Matters On Suspension Parts

Cerakote shows up on premium firearms because it shrugs off abrasion, salt, and road chemicals. Powder coat chips when a rock hits it at 60 mph. Cerakote holds. So when you crawl under your F-150 to chase a squeak, you do not see rust streaks on a fresh set of arms.

For a daily-driven truck that sees winter roads, that finish makes a real difference. Parts that look right at year five beat parts you wish you had coated yourself.

Final Word On The UMI F-150 Upper A-Arms

UMI fatigue and load tested the 6565 kit for street and racing duty before release. The arms ship with zinc-coated grade 8 12-point assembly bolts and the matching socket, so the hardware survives repeated adjustment without stripping. The F-150 release also fits a bigger pattern at UMI. They have been pushing hard into new platforms lately, including the 6th Gen Camaro suspension lineup, and the late-model truck market is the next natural step. For builders chasing the lowered late-model truck look without wrecking front-end geometry, the UMI F-150 upper A-arms are the cleanest option on the market right now.
