Drop your F-150 into a sleek, aggressive stance with real performance to match. UMI pairs coilover front springs and heavy-duty brackets with a shackle/flip rear and Viking double-adjustable shocks to dial ride height and handling for street, canyon runs, or local autocross.
Why it hits
-
Adjustable stance, front & rear: Fine-tune ride height for looks, aero, and geometry.
-
Viking double-adjustables (19/19): Independent 19-click compression and 19-click rebound to sharpen turn-in and ride control.
-
Stronger, smarter hardware: Double-shear front mounts work with factory lower A-arms; HD 4-position shackles with squeak-free Delrin bushings.
-
Street & race proven: Balanced spring rates and damper tuning keep it daily-drivable—until you twist the knobs.
Drop ranges (vehicle dependent)
-
Front: 1.5–4.0" (coilover adjustable)
-
Rear (2WD): 3.5–5.0"
-
Rear (4WD): 4.0–6.5"
Most trucks align happily with ~3–4" front drop on factory A-arms.

Hardware & instructions
-
100% Made in USA
Fitment notes
-
Leaf springs: Works with steel or composite leafs.
-
PowerBoost: Does not fit PowerBoost (driveshaft clearance).
-
Headlight level sensors: Trucks equipped with sensors (many Platinum/Lariat) require bracket p/n 6576.
-
Alignment: Book a professional alignment after install (set factory camber, maximize positive caster within spec).
Ride & handling
-
Daily driver to track-adjacent: Use low-speed compression to curb body roll and rebound to control oscillation.
-
Balanced geometry: Coilover front keeps the nose planted; rear shackle/flip + pinion shims maintain smooth driveline manners.
Install overview
-
Direct bolt-in design — no welding.
-
Front: Swap to UMI coilovers using double-shear mounts (compatible with factory lower A-arms).
-
Rear: Install flip kit/shackles, set the shackle position, add pinion shim/trans spacer to correct driveline angle.
-
Finish: Set shock clicks baseline (e.g., 8C/8R), check tire/wheel clearance, road test, then align.

Builder’s checklist
-
Choose spring rate for your drivetrain (2WD = 600, 4WD = 850).
-
Set your target drop; verify wheel/tire clearance at full lock and compression.
-
Plan for pinion angle setup using included shims/spacer—critical for smooth cruising.
-
If you run headlight level sensors, add p/n 6576.
-
Re-torque after 100–300 miles and after aggressive driving.
