Flatout GR40R Suspension System for 2022–2025 Subaru Outback Wilderness

The Flatout Suspension GR40R is engineered for drivers who push their Subaru Outback Wilderness harder than stock suspensions can handle. Designed for overlanders, adventure rigs, and heavy-duty off-road use, the GR40R builds on the proven GR40 rally-strength foundation and adds external reservoirs on all four shocks to maximize endurance and fade-free performance.

By increasing oil capacity, these reservoirs keep shocks running cooler and smoother, even under heavy loads, rugged trails, or extended off-road trips. Whether hauling rooftop tents, tire carriers, recovery gear, or towing trailers, the GR40R ensures your Outback stays in control in the most demanding conditions.

Key Features of the GR40R Coilovers

• 0–3” Adjustable Ride Height → Optimize stance and clearance for larger tires and rugged terrain.

• External Reservoirs on All Four Shocks → Increased oil volume prevents overheating and reduces damper fade.

• Inverted Heavy-Duty Shock Design → Rally-proven durability for extreme off-road conditions.

• Bypass Piston Valving → Smooths washboard chatter while absorbing large impacts and drops.
