The Dirt Logic 4.0 Resi Coilover [Passenger] is built to deliver maximum off-road damping performance while maintaining excellent highway ride quality. Designed for full-size vehicles that require the strongest and most capable suspension components, this passenger-side specific coilover provides extreme strength, stability, and control in a true bolt-on configuration.
With its massive 4.0-inch shock body and remote reservoir, the Dirt Logic 4.0 significantly increases oil capacity and cooling efficiency. This allows for consistent, fade-resistant performance during aggressive off-road driving and demanding terrain, making it ideal for vehicles equipped with Fabtech front coilover conversion kits.
