Flatout GR40-PRO Coilovers for 2015-19 Subaru Outback

The Flatout GR40-PRO is engineered for drivers who push their Subaru Outback beyond pavement. Designed for hardcore off-roaders, overlanders, and expedition builds, these professional-grade coilovers deliver strength, adjustability, and endurance for the most demanding terrain.

Unlike spacer lifts or basic shock/spring combos, the GR40-PRO features 3-way adjustable inverted shocks, external reservoirs, and advanced valving, giving you complete control over rocks, washboard, sand, and mud. With 0–3” of lift and full damping adjustability, it’s the ultimate suspension upgrade for serious off-road use.
