Key Features

Designed for serious off-road use, the Fabtech Dirt Logic coilovers feature stainless steel construction for superior corrosion resistance and longevity. The 2.5-inch diameter shock body provides increased oil capacity and heat dissipation, ensuring consistent performance even under demanding conditions. These coilovers incorporate a remote reservoir (resi) design, which allows for better oil and nitrogen separation, reducing fade and maintaining optimal damping characteristics during extended off-road sessions.

• Stainless steel construction enhances durability and corrosion resistance, ideal for off-road environments.
• Remote reservoir (resi) design improves heat dissipation and damping consistency during prolonged use.
• Precision-engineered for a 2.5-inch lift, providing increased ground clearance and improved suspension travel.
• High-quality components and TIG-welded construction ensure strength and reliability.
• Optimized valving for improved ride comfort, handling, and off-road capability.
• Designed specifically for GM K1500 models with 4WD systems, including Trail Boss and AT4 trims.

Construction & Design

The Fabtech Dirt Logic coilovers are built with a heavy-duty stainless steel shock body that resists corrosion and withstands harsh off-road conditions. The 2.5-inch diameter piston and high-flow valving provide precise damping control, ensuring a smooth ride on-road and excellent absorption off-road. The remote reservoir is connected via high-pressure hoses, allowing for increased oil capacity and better heat dissipation, which helps maintain consistent damping performance during extended use.

The coilovers feature a monotube design, which offers improved responsiveness and durability compared to twin-tube shocks. The TIG-welded construction and CNC-machined components guarantee a perfect fit and long-lasting performance. These shocks are engineered with a focus on strength, reliability, and ease of installation, making them a top choice for off-road enthusiasts looking to upgrade their suspension system.
