Flatout Suspension GR40: Rally-Strength Lift Kit for 2018–2023 Subaru Crosstrek

The Flatout Suspension GR40 is built for Crosstrek owners who demand more capability, more durability, and more confidence across rough terrain. Designed using rally-inspired shock architecture, the GR40 delivers increased suspension travel, stronger components, and tuned damping that stays controlled under aggressive driving, heavy loads, and extended off-road use.

With its inverted monotube design and performance-focused internals, the GR40 lifts your Crosstrek while maintaining exceptional composure on gravel, washboard, and uneven terrain. If your adventures take you beyond basic fire roads and into more technical or demanding trails, the GR40 is the lift kit that bridges the gap between everyday adventure and true performance off-road capability.
