KSP PERFORMANCE F-150 Upper Control Arm — Adjustable Forged Aluminum for 2-4" Lift, Corrosion-Resistant

KSP PERFORMANCE's forged aluminum upper control arm is an adjustable, corrosion-resistant front A-arm built to correct ball-joint geometry on 2–4" lifted Ford F-150s (2004–2020) and compatible Expeditions/Navigators.

This upper control arm replaces factory components with a one-piece T6 aluminum forging that resists rust, reduces unsprung weight, and restores proper suspension angles for lifted trucks. It pairs a serviceable, greaseable socket with a heat-treated, zinc-nickel coated ball joint and polyurethane bushings designed to handle harsher conditions than original rubber. The unit is machined to precise tolerances and inspected magnetically to catch flaws before installation.

How does this control arm improve handling on a lifted F-150?

Raising a truck changes steering and suspension geometry; this aftermarket arm brings the ball-joint pivot back into a safer operating angle. The extended range of motion in the joint reduces bind during articulation and helps maintain consistent alignment settings, improving steering feel and tire wear.

• Adjustable length to dial in caster and camber after a 2–4" lift
• Greater ball-joint travel than OE parts to avoid binding
• Polyurethane bushings for firmer, more responsive feedback

What makes the construction durable and rust-resistant?

The arm is CNC-machined from a single T6 aluminum forging, eliminating weld seams and weak points that can corrode or fail. The ball-joint pin receives a zinc-nickel coating for long-term corrosion resistance, and each assembly is magnetically inspected to ensure structural integrity before it ships.

• One-piece forged T6 aluminum reduces weight and removes welding failure points
• Zinc-nickel coated, heat-treated ball-joint pins resist corrosion
• Magnetic particle inspection verifies casting/forging quality

How does serviceability and maintenance work with this arm?

KSP PERFORMANCE designed the unit with a greasable socket and replaceable protective dust covers so you can refresh lubricant and flush out contaminants without replacing the whole arm. The tower-style dust boots and KSP protective covers extend joint life, and the metal-to-metal joint performs reliably under load compared with some polymer-style joints.

• Greaseable socket for periodic lubrication and contaminant flushing
• Removable protective covers and tower-shaped dust boots included
• Metal-to-metal ball joint for increased durability over POM designs

Will these arms fit my truck and what clearance considerations exist?

These upper control arms fit Ford F-150 models from 2004–2020 (excluding Raptor models) and are also compatible with 2006–2022 Ford Expedition and Lincoln Navigator. Wheel offset and spacer choices may be necessary to avoid tire-to-arm contact on vehicles with conservative factory wheel offsets.

• Direct fit for 2004–2020 F-150 (not Raptor); 2006–2022 Expedition and Navigator
• If using stock ET44 wheels, at least 1.5" wheel spacers or 0 offset wheels recommended
• Designed for 2–4" leveling lifts; corrects ball-joint geometry within that range

Who is this for: This KSP PERFORMANCE upper control arm is aimed at owners upgrading or repairing the front suspension on lifted Ford trucks who want a durable, serviceable, and rust-resistant solution. It suits off-road enthusiasts who need increased joint travel, daily drivers chasing better steering response after a lift, and technicians seeking a high-quality, inspected replacement that handles seasonal exposure and heavy use.
