The Dirt Logic 4.0 Resi Coilover is built to deliver extreme off-road damping performance while still providing excellent comfort and control on the highway. Designed for full-size vehicles that demand the biggest and strongest suspension components, this high-end coilover offers unmatched strength, stability, and performance in a true bolt-on configuration.
With its massive 4.0-inch shock body and remote reservoir, the Dirt Logic 4.0 dramatically increases oil capacity and cooling efficiency. This allows the shock to maintain consistent, fade-resistant performance during aggressive off-road driving, making it an ideal choice for drivers who push their vehicles in the toughest conditions.
