KSP PERFORMANCE Upper Control Arms for Chevy/GMC 1500 2-4" Lift — Forged Aluminum with Greasable Ball Joints

KSP PERFORMANCE forged aluminum upper control arms replace worn factory arms and restore correct suspension geometry on 2007–2018 Chevy/GMC/Cadillac 1500 trucks with 2–4" lifts.

These aftermarket upper control arms are engineered to suit lifted Silverado, Sierra and related GM trucks that use 2–4" lift spacers or shock extensions. Built from a one-piece, CNC-machined aluminum alloy and fitted with greasable, heat-treated ball joints and protective dust covers, the arms aim to improve durability and alignment range compared with OEM stamped steel pieces.

Will these control arms fit my truck and lift setup?

Yes — these arms are designed for a broad range of GM 1500-series models from 2007 through 2018, including Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche and Escalade. They are specifically intended for vehicles running a 2" to 4" lift using spacers or shock modifications.

• Compatible models: Chevy Silverado 1500, Tahoe, Suburban; GMC Sierra 1500, Yukon, Yukon XL; Cadillac Escalade; 2007–2013 Avalanche.
• Best fit for trucks with 2"–4" lift height.
• Works with lift spacers or extended shocks—verify suspension geometry before installation.

How do these arms improve suspension performance?

The longer range of motion and adjustable geometry help correct caster and camber changes caused by lifts, delivering more predictable steering and reduced undesirable body motions. Because the ball joints are greasable and protected, the components maintain smoother operation over time.

• Adjustable design for fine-tuning caster and camber.
• Greaseable sockets flush out contaminants to extend service life.
• Protective boots and KSP covers reduce debris intrusion.

What materials and construction details matter?

KSP uses a high-quality aluminum alloy in a one-piece forged-style design that resists corrosion and lowers unsprung weight compared with heavy steel arms. Precision CNC machining provides tight tolerances and a clean appearance without welded seams that can weaken over time.

• One-piece aluminum alloy construction for strength and corrosion resistance.
• Heat-treated ball joints with zinc-nickel coating against rust.
• CNC-machined finish for consistent fitment and aesthetics.

How easy is installation and ongoing maintenance?

Installation is a straightforward bolt-in replacement for vehicles within the specified model and lift ranges, but alignment is recommended after mounting. Routine greasing of the ball joints keeps the parts operating smoothly and helps prevent premature wear.

• Direct-replacement fitment for compatible 2007–2018 GM 1500 models.
• Perform wheel alignment after installation to restore correct geometry.
• Periodic greasing via zerk fittings prolongs joint life.

Who is this for: KSP PERFORMANCE forged aluminum upper control arms are intended for owners of 2007–2018 Chevy, GMC or Cadillac 1500-series trucks who have lifted their truck 2–4" or plan to, and who want a durable, lower-weight replacement that restores proper steering and suspension geometry. Installers and DIY truck enthusiasts who value greasable, serviceable ball joints and corrosion-resistant construction will find these arms a practical upgrade over worn OEM units.
