ReadyLIFT SST Upper Control Arms for 3.5" Lift | 2021–2026 Ford F-150
Is This for You?
You're running a 2021–2026 Ford F-150 with 3.5" of front lift and you're experiencing accelerated tire wear, alignment instability, or ball joint binding — all symptoms of a factory upper control arm operating outside its designed geometry range. The ReadyLIFT 67-21350 SST UCAs are the same arms included in ReadyLIFT's full SST Lift Kits, now available standalone for customers who want to upgrade their existing lifted F-150 with corrected suspension geometry, superior pivot durability, and long-lasting ball joint performance.
The Result
One pair of DOM (Drawn Over Mandrel) round tube steel upper control arms with corrected ball joint cup angles engineered specifically for 3.5" lifted F-150 applications. DOM tubing delivers the tightest OD and ID tolerances in the industry and the highest possible weld strength — making these some of the toughest tubular UCAs available. Heavy-duty ball joints on the knuckle end provide superior strength and long service life under the load of heavy aftermarket wheels and tires. ReadyLIFT TCT (Terrain Control Technology) maintenance-free, self-lubricating pivot bushings on the frame end ensure quiet, durable, and stable pivot performance for the life of the arm. Powder-coated finish for long-term corrosion resistance.
Verified Fitment (OFAS Standard)
✅ Fits: 2021–2026 Ford F-150 (with 3.5" of front lift)
❌ Note: These UCAs are engineered for use with 3.5" of front lift — confirm your current lift height before ordering; incorrect lift height pairing will result in improper ball joint angles and geometry

Wheel & Tire Fitment
No wheel or tire restrictions specific to this component. UCAs correct suspension geometry at 3.5" of lift — verify your total front lift height and tire clearance with your existing lift configuration before ordering.
Installation & Engineering Notes
This is a bolt-on UCA replacement. All UCA hardware must be torqued to specification at ride height — do not torque with the suspension hanging. A professional 4-wheel alignment is mandatory post-installation to verify corrected ball joint angles and lock in geometry. Lifting your vehicle raises its center of gravity; exercise appropriate caution on- and off-road. All Advanced Driver Assistance Systems (ADAS) including Ford Co-Pilot360, Pre-Collision Assist, Lane-Keeping System, BLIS, and automatic headlight leveling must be checked and recalibrated after any suspension geometry change.
Engineering Question: What is your current front lift height on your 2021–2026 F-150? These UCAs are engineered specifically for 3.5" of front lift — confirm your exact lift height before ordering to ensure proper ball joint angle correction.
