Flatout GR40R Rally and Extreme Offroad Suspension
Flatout Suspension GR40R – Rally-Strength Coilovers with External Reservoirs
The Flatout Suspension GR40R is designed for drivers who demand more endurance, more control, and more capability from their suspension system. Building on the proven rally-strength platform of the GR40, the GR40R adds external reservoirs on all four shocks — dramatically increasing oil capacity to keep your suspension running cooler and preventing fade during long, punishing sessions.
Whether your build is focused on rally and rallycross competition or a heavy-duty off-road adventure rig, the GR40R delivers the perfect balance of adjustability, strength, and consistency. It’s the next-level suspension upgrade for drivers who push their vehicles harder, carry heavier loads, and need their coilovers to hold up when others fall short.

Enthusiasts Upgrading from the GR40 → Customers who want the same rally-strength platform with enhanced endurance.
The Flatout Difference
Unlike spacer lifts or generic coilover kits, the GR40R is a motorsport-inspired suspension system with professional-grade features like external reservoirs, bypass piston valving, and inverted dampers. It’s engineered to withstand abuse while still delivering comfort on the road, making it equally at home on a gravel rally stage or a loaded overland expedition.
