The Flatout Suspension GR40R is engineered for Subaru Outback owners who demand strength, adjustability, and endurance for heavy-duty off-road and overland use. Built on the proven GR40 rally-strength foundation, the GR40R adds external reservoirs on all four shocks to maximize cooling, fade-free performance, and long-term reliability.
