KSP PERFORMANCE Adjustable Upper Control Arms for F-150 2021–26 — 2–4" Front Lift, Greasable Ball Joint & PU Bushings

The KSP PERFORMANCE adjustable upper control arms replace factory fixed-angle UCAs to correct alignment and clearance on 2021–2026 F-150 trucks lifted 2–4 inches while adding a greasable ball joint and durable PU bushings.

Built specifically for 2021–2026 Ford F-150 (excluding Raptor), these aftermarket upper control arms are engineered to restore proper suspension geometry after a front lift. They use thicker cold-drawn tubing, CNC-machined connections, and heat-treated alloy ball pins to withstand heavier wheels and tires. Powder-coat protection and a pre-installed dust boot increase longevity, while the greasable socket lets you flush contaminants and maintain smooth operation.

How do these UCAs restore alignment after a 2–4" front lift?

Raising the front of your F-150 changes caster and camber angles, which can cause uneven tire wear and handling issues. The adjustable length and redesigned pivot geometry of the KSP arms let you return caster and camber nearer to factory specs, improving tracking and steering stability. Installation corrects the scrub radius and helps tires sit squarely on the road.

• Adjustable length to dial in caster/camber after lift
• Cold-drawn thick tubing resists bending under load
• Hex access on the ball pin simplifies installation and alignment
• Pre-set dust boot and greasable socket reduce wear and contamination

Will these control arms fit my F-150 and larger wheel setups?

These UCAs are designed for model years 2021–2026 Ford F-150 (not compatible with Raptor). KSP simulated common big-wheel combinations and upgraded the arms to avoid interference with 20x8.5 ET44 wheels and 275/60R20 tires on high-trim models. Double-check your year and model before ordering to ensure fitment.

• Fitment: 2021, 2022, 2023, 2024, 2025, 2026 F-150 (excludes Raptor)
• Engineered to clear 20x8.5 ET44 wheels and 275/60R20 tires in tested layouts
• Adjustable for 2–4" front lift applications
• Recommended to verify vehicle year/make/model prior to purchase

What materials and components improve durability and maintenance?

KSP upgraded core components to extend service life under off-road and heavy-duty use. The ball joint features a high-frequency heat-treated alloy pin and a greasable socket; the control arm body uses thicker, CNC-machined tubing with a powder-coated finish to resist corrosion. PU bushings provide temperature-resistant compliance and longer life than standard rubber.

• Powder-coated surface resists rust and corrosion
• High-frequency heat-treated alloy steel ball pin for strength
• Greaseable ball joint and zerk fitting for serviceability
• PU bushings for improved durability in varied climates

How difficult is installation and what should I know about maintenance?

Installation is straightforward for someone familiar with suspension work, but alignment after installation is required. The ball pin includes a hex hole to ease torquing. For maintenance, the new ball joint typically does not need extra grease within the first year; afterward use the zerk fitting but avoid excessive force when tightening to prevent damage.

• Hex hole on ball pin simplifies tightening during install
• Pre-installed dust boot protects socket components from wear-causing contaminants
• New ball joints: no extra grease needed within the first year
• When greasing, tighten zerk gently and do not overtighten copper fitting

Who is this for: These KSP PERFORMANCE adjustable UCAs suit F-150 owners who have lifted the front 2–4 inches and need stronger, adjustable arms to correct suspension geometry and clear larger wheels and tires. They’re intended for DIY mechanics, installers, and truck enthusiasts who want durable, serviceable control arms with improved materials and replaceable greasable components. KSP offers a 30-day refund and 12-month free replacement policy for added confidence—confirm vehicle fitment before purchase.
