Fabtech 2019 GM K1500 Trail Boss/AT4 4WD 1.5in Ball Joint UCA System - Component Box

When you're lifting your 2019-2021 Chevrolet Silverado 1500 or 2019-2021 GMC Sierra 1500, especially with a 1.5-inch lift, the front suspension geometry changes. This Fabtech Ball Joint UCA System, part number FTS21271, is designed to correct that geometry. You get a set of tubular upper control arms (UCAs) and heavy-duty ball joints. These components work together to ensure your front suspension can be properly aligned after the lift is installed, which is crucial for tire wear and handling.

The design of these UCAs is specifically for the newer GM truck suspension geometry introduced in 2019. This means you won't need additional differential drop brackets to keep your CV axles operating within their intended range, simplifying the installation process. The tubular construction offers a strong yet relatively lightweight solution for the front end, built to handle the stresses of performance driving and off-road use. The heavy-duty ball joints are a key part of this system, providing a robust connection point that's designed to meet the demands of lifted trucks.

This component box includes the upper control arms and the necessary heavy-duty ball joints to complete the upgrade. Installing these UCAs is a common step when lifting these trucks to ensure proper alignment and prevent premature tire wear. Always refer to the manufacturer's installation instructions for specific details on mounting and alignment procedures after installation.
