KSP PERFORMANCE F-150 Adjustable Upper Control Arms 2021-2026 2-4in Front Lift, Greasable Ball Joint

KSP PERFORMANCE adjustable upper control arms replace factory fixed-angle arms to restore alignment and allow 2–4 inches of front lift on 2021–2026 F150 models (excluding Raptor).

These aftermarket upper control arms are engineered to correct caster and camber geometry after a suspension lift, using hardened, greasable ball joints and PU bushings to improve longevity and handling. Designed to fit 2021–2026 F150 trucks (not compatible with the Raptor), the KSP UCAs come powder-coated for corrosion resistance and built from thickened cold-drawn steel to endure lifted chassis demands. The arms are pre-assembled with dust boots, include a hex hole ball pin for simple installation, and are validated to clear common wheel/tire combos such as 20x8.5 ET44 wheels with 275/60R20 tires on higher-output models.

How do these upper control arms correct alignment after lifting my F150?

The KSP UCAs provide adjustable geometry that re-centers caster and camber to factory-like specifications after installing a 2–4" front lift. By changing the arm length and ball joint position, they remove the excessive negative camber and undue stress on steering components that lifting can create.

• Adjustable length to dial in caster/camber alignment.
• Greasable ball joints let you maintain smooth articulation.
• PU bushings resist deformation across temperature ranges.
• Pre-installed dust boots protect the joint from contaminants.

What materials and processes make these upper control arms durable?

KSP builds these UCAs from thickened, cold-drawn steel tubing and uses heat-treated alloy for the ball pin, delivering a robust structure that resists bending and fatigue. The powder-coated finish reduces corrosion, while greasable joints and durable bushings extend service life in harsh driving conditions.

• Cold-drawn steel pipe for increased structural strength.
• Heat-treated alloy ball pin for wear resistance.
• Powder-coating for long-term rust protection.
• Greasable socket and dust boots to flush contaminants.

How straightforward is installation and maintenance?

Installation is simplified by features like a hex-hole ball pin for easier torque application and pre-installed dust boots that save assembly steps. Routine maintenance is minimal: the ball joint is greasable, but new joints typically don’t require extra grease within the first year; afterward, use the supplied zerk fitting cautiously to avoid damage.

• Hex hole on the ball pin for easier tightening during install.
• Greasable zerk fitting for periodic lubrication—avoid over-tightening.
• Pre-assembled components reduce install time and errors.
• Compatibility check recommended before purchase.

Will common wheel and tire setups fit without rubbing the control arms?

KSP simulated fitment in three-dimensional models to ensure the upgraded control arm clears popular wheel/tire combinations used on lifted F150s. This reduces the risk of contact with 20x8.5 ET44 wheels and 275/60R20 tires on high-output variants, though final fit depends on specific offsets and lift configurations.

• Verified clearance with 20x8.5 ET44 and 275/60R20 in test simulations.
• Designed for lifted chassis to avoid interference during suspension travel.
• Not intended for Raptor models—confirm model year before buying.
• Final fit may vary with wheel backspacing, tire width, and lift setup.

Who is this for: These adjustable upper control arms suit F150 owners (model years 2021–2026) who have installed or plan to install a 2–4" front lift and need to restore proper steering geometry and durability. They are aimed at DIY installers and professional shops looking for greasable joints, heavy-duty construction, and a corrosion-resistant finish. If you own a Raptor or a model outside the supported years, choose a model-specific alternative. KSP PERFORMANCE provides a 30-day refund and a 12-month replacement warranty—contact the seller for fitment assistance or warranty support.
