KSP 2021+ F150 Upper Control Arms 2-4in Adjustable Front Lift

In this review of the KSP 2021+ F150 Upper Control Arms the bottom line is simple: these are a heavy-duty, adjustable replacement for the factory fixed-angle arms designed for 2021-2024 F150s that need proper caster/camber correction after a 2-4in lift. The reviewer found they deliver stronger construction and greasable ball joints that make maintenance straightforward, and the single biggest reason to buy is the combination of thicker cold-drawn steel and a powder-coated finish that resists corrosion while correcting geometry for larger wheel and tire setups.

Key Features

• Fitment: Designed specifically for 2021-2024 F150 models so buyers can expect direct compatibility except for the Raptor variant.
• Adjustability: Adjustable design corrects control arm angle after a 2-4in front lift to restore proper alignment and handling.
• Durable construction: Thickened cold-drawn steel pipe and CNC machined components provide a stronger pipe diameter that resists bending under load.
• Upgraded ball joint: High frequency heat treated alloy steel ball pin with a greasable zerk improves durability and allows flushing of contaminants.
• Corrosion resistance: Powder coated surface reduces rust and helps the arms maintain appearance and function in wet or salty environments.
• Installation-friendly: Pre-installed dust boots, a hex hole on the ball pin, and included mounting hardware simplify fitment for most DIY installers.

Who It's For

This product suits F150 owners (model years 2021 through 2024) who have lifted their trucks 2-4in and need a stout, adjustable upper control arm to correct suspension geometry and avoid tire rubbing when running larger wheels and tires. It is also a good match for those who prefer greasable joints and tougher materials than stock for off-road or heavy-duty use.

Those who should look elsewhere include Raptor owners, since these arms do not fit that model, and buyers who need a different fitment outside the specified model years. If you require a non-greasable, factory-style fixed arm, these upgraded adjustable arms may be more than you need.

Pros & Cons

Pros

• Heavy-duty build and CNC machining produce a robust arm that feels safer under load.
• Greasable ball joint and pre-installed dust boot enable easier maintenance and longer life.
• Powder coated finish resists rust and keeps components protected in harsh conditions.
• Designed to clear 20x8.5 ET44 wheels with 275/60R20 tires on high-powered models without interference.

Cons

• Not compatible with F150 Raptor models, so verify fitment before ordering.
• Care is required when greasing the zerk to avoid breakage, and new ball joints do not need extra grease for the first year.

Our Verdict

The KSP 2021+ F150 Upper Control Arms are a practical upgrade for non-Raptor F150 owners who run a modest 2-4in lift and want to restore correct suspension geometry with durable parts. They offer solid build quality, greasable joints, and corrosion protection at a price that represents good value for drivers who plan to keep their truck lifted and driven in mixed conditions.

Frequently Asked Questions

Will these fit my 2020 F150?
These arms are specified for 2021-2024 F150 models; compatibility with 2020 is not guaranteed.

Do the ball joints need immediate greasing?
New ball joints do not require extra grease within the first year; when greasing later, tighten the zerk carefully to avoid damage.

Will these clear 20 in wheels and 275 tires?
KSP simulated clearance for 20x8.5 ET44 wheels with 275/60R20 tires on high-powered models to avoid friction with the arm.
