Overview

The Fabtech 3.5-inch Front Upper Control Arm System with 2.5-inch Dirt Logic Coilovers and Rear Dirt Logic Shocks is a comprehensive suspension upgrade designed specifically for GM K1500 trucks from 2007 to 2018. This system is engineered to enhance your vehicle’s off-road capability, improve ride quality, and provide a more aggressive stance, making it ideal for enthusiasts who demand durability and performance both on and off the pavement.

Whether you're tackling rugged trails, hauling loads, or simply looking to upgrade your truck’s handling and appearance, this control arm system offers a significant upgrade over stock components. The system combines high-quality materials and precision engineering to deliver a reliable, long-lasting suspension solution that supports increased wheel travel, better articulation, and improved stability.

Key Features

Designed with performance and durability in mind, the Fabtech control arm system incorporates several advanced features:

• Heavy-duty upper control arms constructed from high-strength steel with a durable black powder coat finish for corrosion resistance and long-lasting performance.
• 2.5-inch Dirt Logic coilovers featuring remote reservoirs for superior heat dissipation and consistent damping during demanding off-road use.
• Rear Dirt Logic shocks engineered to provide excellent ride quality and stability, whether on rough trails or paved roads.
• Precision CNC-machined mounting points and high-quality bushings ensure a secure fit and smooth operation.
• Enhanced wheel travel and articulation, allowing your truck to navigate challenging terrain with confidence.
• Improved handling and stability thanks to the optimized geometry and high-performance shock absorbers.
• Made in the United States, ensuring strict quality control and manufacturing standards.
• Includes all necessary hardware and components for a complete installation, reducing downtime and installation complexity.

Construction & Design

The control arms are crafted from high-strength steel and feature a robust design that withstands the rigors of off-road driving. The use of CNC-machined mounting points guarantees precise alignment and fitment, while the black powder coat finish provides excellent corrosion resistance. The Dirt Logic coilovers are built with a monotube design and remote reservoirs, offering superior damping control and heat dissipation for consistent performance during extended off-road sessions. The rear shocks are similarly engineered for durability and ride quality, completing a suspension system that balances strength, flexibility, and comfort.

Performance & Sound

This suspension upgrade significantly improves your truck’s off-road capability by increasing wheel travel and articulation, allowing for better traction and control over uneven terrain. The high-performance coilovers and shocks help absorb impacts and reduce body roll, resulting in a smoother ride both on and off the pavement. While primarily focused on performance and durability, this system also enhances the aggressive stance of your truck, giving it a commanding presence.

Installation & Fitment

The Fabtech control arm system is designed as a bolt-on upgrade, making installation straightforward for experienced DIY enthusiasts or professional installers. All components are engineered to fit directly onto your GM K1500 without the need for cutting or extensive modifications. However, a proper alignment is recommended after installation to ensure optimal handling and tire wear. No additional tuning or specialized tools are required, and the system is built to integrate seamlessly with your vehicle’s existing suspension geometry.
