KSP 2-4 in. K1500 Upper Control Arms – Adjustable Front UCA for Chevy/GMC 1988-1999

Premium design for classic Chevy and GMC K1500s

Meet the KSP PERFORMANCE 2-4 in. K1500 Upper Control Arms, engineered to support lifted or stock-height suspensions on 1988–1999 Chevy and GMC 4WD trucks. These adjustable UCAs are designed for 6-lug wheels and work with compatible knuckles. They are not a universal fit for straight-front-axle configurations, so verifying the year, make, and model before purchase helps ensure proper compatibility.

What makes these arms stand out

Build quality and material choices are designed for durability in demanding conditions. A powder-coated surface resists rust and corrosion, while CNC machining ensures precise pipe diameter. The ball pin is crafted from high-frequency heat-treated alloy steel, delivering strength where it matters most, and a thickened cold-drawn steel tube helps maintain correct chassis geometry after lifting.

• Dom tuber arms address common fitment challenges after lifting, aiding alignment across a range of setups.
• The ball pin includes a hex hole for easier installation, and a pre-installed dust boot shields components from contaminants.

Key features for performance and maintenance

• Greaseable socket design lets you introduce lubricant to flush contaminants, reducing corrosion risk over time.
• PU bushings balance ride comfort and control, performing reliably in varied weather and road conditions.
• Powder-coated finish plus robust steel construction provide durable, off-road-ready protection.
• Hardened ball joint design and a heavy-duty pipe help extend the lifespan under demanding use.

Care and compatibility notes: Always recheck year/make/model in the product description to confirm fitment with your vehicle. If your setup uses aftermarket knuckles, please contact us for guidance. After installation, follow standard torque specifications and periodically recheck fasteners to maintain optimal performance.
