KSP PERFORMANCE Front Upper Control Arms for Silverado/Sierra 1500 (1999–2006) — 2–4" Adjustable Tubular A-Arms, Black, Heavy-Duty

These KSP PERFORMANCE front upper adjustable tubular control arms replace factory A-arms to correct geometry and steering after a 2–4" lift on Chevy, GMC, Cadillac 1500-series trucks (1999–2006).

When you lift a full-size pickup or SUV, stock upper control arms often sit at the wrong angle, causing uneven tire wear, poor alignment, and compromised steering feel. KSP PERFORMANCE engineered these tubular, adjustable front upper control arms to restore proper suspension geometry for 2–4 inch lifts, using thicker cold-drawn tubing, greaseable sockets, and heavy-duty ball joints. The powder-coated finish and CNC-machined components aim to deliver corrosion resistance and consistent fit on a wide range of GM platforms.

How do these control arms improve handling after a lift?

By replacing the factory upper arms with adjustable tubular A-arms, the suspension’s caster and camber can be returned closer to OEM angles, which stabilizes steering and reduces premature tire wear. The stronger pipe diameter and high-frequency heat-treated ball pin help maintain alignment under load.

• Adjustable length corrects caster/camber for 2–4" lifts.
• Cold-drawn steel tubing resists bending and flexing.
• High-frequency heat-treated ball pin increases durability.
• Greaseable socket allows periodic lubrication to extend life.

Will these arms fit my truck or SUV model?

KSP lists broad compatibility across many GM 1500-series vehicles from 1999–2011 depending on model; always verify your year, make, and model against the fitment list before ordering. The set includes two upper control arms designed for vehicles lifted 2–4 inches and intended to replace factory or stock suspension arms.

• Fits Chevy Silverado 1500 (1999–2006) and Avalanche 1500 (2002–2006).
• Compatible with Tahoe, Suburban 1500, Express, and similar GM platforms.
• Works on GMC Sierra/Yukon series and Cadillac Escalade 2002–2006 variants.
• Verify fitment for Savana, Escalade EXT, and Escalade ESV where listed.

What are the construction and maintenance details I should know?

The arms are formed from thickened, cold-drawn steel tube, CNC-machined for accurate diameters, and finished with a powder coat to resist rust. Ball joints include a hex hole for installation; sockets are greasable and come with a pre-installed dust boot to limit contamination.

• Powder coated surface for corrosion protection.
• Pre-installed dust boots shield socket components from dirt and moisture.
• Greaseable sockets allow flushing of contaminants; tighten zerk fittings after greasing.
• New ball joints generally do not require additional grease within the first year.

How difficult is installation and what should I prepare?

Installation requires basic suspension tools and a lift or jack stands; tightening torque specs and alignment are essential after installation. These arms include installation-friendly features like hex-hole ball pins, but professional alignment after reassembly is recommended to ensure safe steering and even tire wear.

• Requires removal of factory upper arms and installation of adjustable tubular replacements.
• Hex-hole ball pin simplifies tightening during assembly.
• Re-torque zerk fittings after lubrication; avoid excessive force to prevent damage.
• Schedule a wheel alignment after installation for correct caster/camber.

Who is this for: These KSP PERFORMANCE front upper control arms are aimed at owners of Chevy, GMC, or Cadillac 1500-series trucks and SUVs who have added a 2–4 inch lift and need to restore proper suspension geometry. They suit DIY mechanics comfortable with suspension work, off-road enthusiasts wanting stronger components, and anyone seeking a long-lasting replacement that improves steering stability and reduces uneven tire wear after lifting their vehicle.
