The Dirt Logic 4.0 Resi Coilover [Driver] is engineered to deliver uncompromising off-road damping performance while maintaining excellent highway comfort. Designed specifically for full-size vehicles, this driver-side coilover provides extreme strength, stability, and control in a true bolt-on configuration.
With its massive 4.0-inch shock body and high-capacity remote reservoir, the Dirt Logic 4.0 dramatically increases oil volume and heat dissipation. This ensures consistent, fade-resistant performance during aggressive off-road driving and demanding terrain, making it the ultimate suspension upgrade for vehicles equipped with Fabtech front coilover conversion kits.
