KSP PERFORMANCE Silverado/Sierra Upper Control Arms — Forged Aluminium UCA for 2–4" Lift, Greasable Ball Joints

KSP PERFORMANCE forged aluminum upper control arms replace worn stock UCAs and are engineered to work with 2–4" lifts on 2007–2018 Chevy Silverado, GMC Sierra and similar platforms.

These aftermarket upper control arms are a direct-fit replacement for many GM trucks and SUVs, designed to restore steering geometry and improve front suspension durability after installing a 2–4" lift (spacers or shocks). Built from a single-piece forged aluminum alloy and finished with precision CNC machining, the arms are lighter than steel, corrosion-resistant, and serviceable with greasable ball-joint sockets and protective dust covers.

Will these upper control arms fit my Chevy or GMC with a 2–4" lift?

Yes — the KSP PERFORMANCE UCAs specifically cover most 2007–2018 Silverado 1500, Sierra 1500, Tahoe, Yukon, Suburban, Yukon XL 1500, Escalade and 2007–2013 Avalanche models when used with a 2–4" lift setup. They’re intended as a direct replacement to correct altered suspension geometry that occurs after lifting.

• Compatible models: 2007–2018 Silverado/Sierra 1500, Tahoe, Suburban, Yukon, Yukon XL, Escalade; 2007–2013 Avalanche.
• Designed for 2–4" lift heights using spacers or longer shocks.
• Direct-fit bolt locations for stock-style installations—no major fabrication required.

How do these aluminum UCAs improve suspension performance?

Upgraded UCAs let you restore proper steering and wheel alignment after a lift, reducing abnormal tire wear and improving handling. The adjustable design lets you fine-tune camber and caster to suit towing, hauling, or off-road conditions while the lightweight forged aluminum reduces unsprung mass for crisper response.

• Adjustability helps correct caster/camber changes from lifting the truck.
• Forged aluminum reduces weight compared with heavy steel arms.
• Serviceable greasable joints and dust boots extend service life under harsh conditions.

What makes KSP PERFORMANCE’s ball joint and construction durable?

KSP UCAs use heat-treated ball joints with a zinc-nickel alloy coating to resist corrosion better than uncoated ferrous joints. Each ball joint includes a tower dust boot plus an exclusive KSP protective cover, and greasable sockets allow periodic lubrication to clear out contaminants and reduce wear.

• Heat-treated ball joints with zinc-nickel coating for corrosion resistance.
• Dual protection: tower dust boots plus protective covers against debris.
• One-piece forged aluminum construction avoids weld failure points common to multi-piece arms.

How do I install and maintain these upper control arms?

Installation follows standard UCA replacement procedures — remove the old upper arm, transfer necessary hardware, and align to factory torque specs. After installation, have a professional alignment performed; occasional greasing of the ball-joint fittings will maximize service life.

• Installation: direct-fit for listed models; typical hand tools required.
• Maintenance: grease fittings accessible for routine lubrication.
• Post-installation: professional wheel alignment is recommended.

Who is this for: KSP PERFORMANCE forged aluminum upper control arms are aimed at truck owners who have lifted their 2007–2018 GM 1500-series vehicles 2–4" and want a durable, lighter-weight replacement to correct suspension geometry. They suit drivers who need stronger-than-stock components for off-road use, towing, or everyday driving while prioritizing corrosion resistance and serviceable joints. If you’re replacing worn UCAs after a lift or upgrading to adjustable arms to dial in alignment and handling, these KSP arms are designed to deliver long life and improved front-end control without complex fabrication.
