KSP Forged Upper Control Arm for Silverado/Sierra 2007-2018 – 2pc Adjustable Front Aluminum UCA with Greasable Ball Joint

Overview

The KSP Forged Upper Control Arm kit is designed for Silverado/Sierra 1500 trucks from 2007–2018. This two-arm front UCA upgrade is tailored for lifted setups, specifically 2-4 inches of suspension height increase. Each arm features a one-piece forged aluminum body, delivering a strong, lightweight alternative to traditional iron components. The material choice helps resist rust and corrosion, which is especially valuable in winter conditions and on salted roads. Before leaving the production line, every arm undergoes magnetic particle inspection to verify integrity and finish, giving you confidence in the build quality.

Durability and Precision

• Two one-piece forged aluminum arms provide robust rigidity with lighter weight.
• Precision CNC machining ensures accurate dimensions for a consistent fit.
• Rust resistance is built into the design, helping longevity in challenging climates.
• Greasable sockets enable fresh lubrication to flush out contaminants, potentially extending service life.

Protection, Maintenance, and Longevity

The ball joints are paired with tower dust boots and exclusive protective covers to minimize debris exposure. Zinc-nickel coated ball joint pins add another layer of corrosion resistance, supporting steady articulation under load. This metal-to-metal joint design aims to deliver reliable movement compared with less robust alternatives.

Lift Compatibility and Real‑World Use

Designed for trucks with a 2-4 inch lift, this kit offers a greater range of motion that can help with chassis alignment and steering feel on both paved roads and rougher terrain. It is important to note that compatibility varies with specific knuckle configurations; models equipped with a 3.5 inch lifted knuckle kit may not be compatible.

Performance under Temperature and Terrain

• Premium polyurethane bushings resist extreme temperatures and maintain consistent feedback.
• Groove design supports lubrication flow, contributing to smoother operation and reduced noise.

What to Expect

In everyday driving, you may notice steadier front-end behavior and improved geometry across uneven pavement and off-road surfaces. While results depend on your overall suspension setup, this KSP UCA upgrade aims to provide durable, serviceable performance for lifted Chevy and GMC trucks without overpromising outcomes.
