KSP PERFORMANCE Forged Upper Control Arms for 2007-2018 Silverado/Sierra 1500, 2pc 2-4in Lift, Aluminum w/ Greasable Ball Joints

KSP PERFORMANCE Forged Upper Control Arms are one-piece, CNC-machined aluminum UCAs designed to replace stock arms on 2007–2018 Chevy Silverado and GMC Sierra 1500 trucks with 2–4" of lift.

These upper control arms deliver a corrosion-resistant, serviceable alternative to factory steel arms for lifted Silverado and Sierra trucks. Built from forged T6 aluminum and finished with precision machining, the set includes greasable, zinc-nickel coated ball joints and polyurethane bushings to improve durability, steering feel, and suspension geometry for lifted applications. They are engineered to fit most 2–4" lift setups while offering increased articulation and reduced maintenance compared with OEM parts.

Will these control arms fit my lifted Silverado or Sierra?

They are intended for 2007–2018 Silverado and Sierra 1500 models when the truck has roughly 2–4" of lift. They provide the corrected ball joint angle and extra travel needed for common suspension lifts, but they are not compatible with 3.5" lifted knuckle kits.

• Vehicle fit: Chevy Silverado / GMC Sierra 1500 (2007–2018).
• Recommended lift range: 2–4" for best performance.
• Not compatible with specific 3.5" lifted knuckle kits.
• Sold as a 2-piece set for both driver and passenger sides.

How do these UCAs hold up to rust, wear, and off-road use?

The arms use forged T6 aluminum and a one-piece construction, eliminating welds and weak points that commonly corrode or fatigue. Ball joints are heat treated and coated with a zinc-nickel finish, and the polyurethane bushings resist temperature extremes and reduce noise compared to rubber.

• One-piece forged aluminum resists rust and eliminates weld failure points.
• Zinc-nickel coated ball joint pins for extended corrosion protection.
• Serviceable greasable sockets extend joint life and flush contaminants.
• Polyurethane bushings improve durability and deliver firmer feedback.

What maintenance and service options are available?

These control arms are designed with serviceability in mind: greasable sockets let you add lubricant to purge grit and moisture, and replaceable boots help shield the ball joints from debris. Routine greasing will prolong service life, especially after wet or muddy driving.

• Greasable ball joint sockets allow periodic lubrication.
• Protective dust boots and KSP covers help keep contaminants out.
• Metal-to-metal ball joint design avoids premature softening issues.
• Magnetic particle inspected during production for structural integrity.

How will these UCAs change driving experience and alignment?

With corrected geometry for lifted trucks, the arms reduce abnormal camber and steering pull, offering a wider range of motion than stock ball joints. Drivers typically notice firmer steering feedback and reduced noise, particularly when navigating uneven roads or trails.

• Improved ball joint angle for lifted suspension geometry correction.
• Greater articulation helps maintain tire contact over rough terrain.
• Polyurethane bushings reduce deflection and road noise.
• Helps maintain alignment settings longer under lifted conditions.

Who is this for: KSP PERFORMANCE Forged Upper Control Arms suit owners of 2007–2018 Chevy Silverado and GMC Sierra 1500 trucks who run a 2–4" lift and want a durable, serviceable upgrade over OEM steel arms. They’re a smart choice for daily-driven lifted trucks and off-road enthusiasts seeking improved suspension geometry, corrosion resistance, and easier maintenance without stepping up to custom knuckle systems.
