Flatout GR40R Suspension for 2019–24 Subaru Forester

The Flatout GR40R Coilover System is engineered for serious off-roaders, overlanders, and expedition builds. Based on our rally-proven GR40 platform, the GR40R adds external reservoirs on all four shocks, delivering fade-free performance even under heavy loads, rough trails, and extended adventures.

This heavy-duty coilover system is ideal for rigs carrying rooftop tents, spare tires, bumpers, or recovery gear, ensuring your Forester maintains control, ride quality, and durability no matter the terrain.

Why Choose the GR40R?

• Fade-Free Performance → External reservoirs increase oil capacity, keeping shocks cooler under extreme use.

• Heavy-Duty Strength → Inverted shock design and bypass piston valving handle rocks, drops, and washboard roads.

• Adjustable Ride Height → 0–3” lift lets you optimize clearance and stance for bigger tires or rugged terrain.

• Overload-Capable Springs → Optional spring upgrades support heavy builds, rooftop tents, or added cargo.

• Rebuildable Design → Long-term serviceability for expedition and adventure rigs.

• Corrosion-Resistant → Electroplated shock bodies protect against mud, snow, and salt for 7–10 years.
