KSP PERFORMANCE Front Upper Control Arms for Silverado & Sierra 1500 — 2-4" Adjustable Tubular A-Arms, Greaseable Black Pair

KSP PERFORMANCE front upper control arms are a pair of adjustable tubular A-arms designed to replace factory arms after a 2–4" lift on 1999–2006 Chevy and GMC 1500-series trucks and SUVs, restoring proper alignment and suspension geometry.

If you've lifted a Silverado, Sierra, Tahoe, Yukon or related GM 1500-series vehicle, the stock upper control arms often no longer align correctly with the chassis. These KSP PERFORMANCE tubular control arms are engineered to correct the suspension geometry created by a 2–4" lift, using heavy-duty materials, CNC machining and greaseable joints to suit off-road and lifted-street use.

How do these control arms correct handling after a 2–4" lift?

Raising the ride height changes caster and camber angles; these adjustable A-arms reposition the upper ball joint and restore alignment range. The tubular design and adjustable length let you dial in correct geometry without bending factory components.

• Adjustable length to compensate for 2–4" lift
• Tubular construction maintains strength and reduces weight
• CNC-machined connections for precise fitment
• Pre-installed dust boots and greaseable sockets to protect joints

What materials and manufacturing features improve durability?

These arms use thickened cold-drawn steel tubing and high-frequency heat-treated alloy ball pins for enhanced fatigue resistance. A durable powder-coat finish prevents rust, while PU bushings and greaseable joints extend service life in varied temperatures.

• Powder-coated surface to resist corrosion
• Cold-drawn steel tubing for structural integrity
• Heat-treated alloy ball pin for stronger joint performance
• Polyurethane bushings for long-lasting, temperature-resistant operation

Which vehicles and model years are compatible?

These KSP PERFORMANCE upper control arms are engineered for a wide range of GM 1500-series models spanning late 1990s through mid-2000s. Confirm your exact year, make and model before purchase to ensure a proper fit.

• Chevy Silverado 1500 (1999–2006)
• Chevy Avalanche 1500 (2002–2006), Suburban & Tahoe (2000–2006)
• GMC Sierra 1500 (1999–2006), Yukon & Yukon XL 1500 (2000–2006)
• Express/Savana 1500 (2003–2013), Cadillac Escalade series (2002–2006)

How should these arms be maintained for long life?

Periodic greasing of the zerk fittings preserves the internal socket and reduces wear—avoid over-tightening the zerk to prevent damage. New ball joints typically do not require additional grease within the first year; always follow installation torque specs and check fittings after initial road miles.

• Tighten zerk fittings after refilling grease, but don’t overtighten
• New ball joints: no extra grease needed within the first year
• Inspect dust boots and bushings periodically for damage
• Recheck alignment after installation and after first few hundred miles

Who is this for: These control arms are aimed at truck and SUV owners who have lifted their 1999–2006 GM 1500-series vehicles by 2–4 inches and need a robust, adjustable replacement to restore proper suspension geometry. Installers range from experienced DIYers with alignment tools to professional shops upgrading lifted rigs for improved on- and off-road handling. If you require corrosion-resistant components, greaseable joints and polyurethane bushings for extended service life, these KSP PERFORMANCE tubular A-arms are built to meet those needs.
