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