KSP PERFORMANCE Upper Control Arm for F-150 (2004–2020) — 2–4" Front Lift, Red, Adjustable Ball Joint, Reinforced Steel

KSP PERFORMANCE 2-4" Upper Control Arm replaces factory arms on 2004–2020 F-150s to safely support 2–4 inch front lifts with adjustable ball joints and reinforced steel construction.

These aftermarket upper control arms are engineered to take the place of worn or stock arms when lifting your F-150 between 2 and 4 inches. Built from heavy tubular steel with MIG-welded joints and polyurethane bushings, the units are tuned to preserve suspension geometry while offering improved durability for street and off-road driving. Ball joints come pre-greased and are adjustable to help restore proper wheel alignment after installation.

How do these arms fit my F-150 and lift setup?

The KSP upper control arms are designed specifically for Ford F-150 model years 2004 through 2020 and intended for front-lift heights of roughly 2 to 4 inches. If you run wider tires on factory wheels, wheel spacers may be needed to avoid rubbing. After installing, wheel alignment is required to ensure correct handling and tire wear.

• Vehicle compatibility: 2004–2020 Ford F-150
• Optimized for 2–4" front lift kits
• Wheel spacers recommended for larger tires on stock wheels
• Professional alignment advised after installation

What materials and construction improve strength and reliability?

These arms use 1.25" DOM tubular steel and MIG welding throughout critical seams for a stiff, reinforced structure. The larger-diameter tubing and robust welds resist flex under load, helping retain correct suspension geometry during heavy use. A durable red finish protects the metal from corrosion and road debris.

• 1.25" DOM tubular steel for increased rigidity
• MIG-welded joints for consistent structural strength
• Protective red coating to resist corrosion
• Dust caps over joints to extend service life

How are the joints and bushings designed for performance?

KSP uses polyurethane (PU) bushings instead of rubber to reduce degradation in low temperatures and provide firmer control under load. Ball joints come pre-greased for immediate use and include a zerk fitting for future servicing—take care not to over-tighten the zerk as it’s copper and can snap if overtightened.

• PU bushings for longer life and improved low-temperature performance
• Pre-greased adjustable ball joints for quick installation
• Serviceable zerk fittings—tighten gently after greasing
• Dust caps increase joint longevity

What installation and maintenance notes should I know?

Installation requires standard mechanical competency and the ability to safely lift and support the vehicle. After fitting the arms, a full alignment is necessary. Ball joints are pre-lubricated and typically do not need grease for the first year; thereafter use the zerk to refill but avoid overtightening the fitting.

• Professional or experienced DIY installation recommended
• Alignment required following installation
• Ball joints pre-greased—no grease needed for about one year
• Use zerk fitting for maintenance; avoid over-tightening

Who this product is for: The KSP PERFORMANCE 2-4" Upper Control Arm is intended for F-150 owners upgrading to a modest front lift who want a strong, serviceable replacement for worn or stock arms. It's a fit for drivers running light- to heavy-duty street and off-road use who value reinforced construction, adjustable ball joints for correct alignment, and polyurethane bushings for improved longevity. Reach out to KSP customer support if you plan to pair aftermarket wheels or significantly different tire sizes so fitment can be confirmed before purchase.
