Flatout GR40 Coilovers – 1–3” Lift Rally-Inspired Suspension System

The Flatout GR40 Coilovers are designed for 2005–2010 Jeep Grand Cherokee owners who want a suspension system that balances daily driving comfort with true off-road and rally performance. With 1–3 inches of lift over stock, the GR40 provides the ground clearance needed for trails, rallycross, overland adventures, and rugged off-road conditions while maintaining smooth handling on paved roads.

Built for strength and durability, the GR40 features inverted front shocks and external reservoir rear shocks, engineered to withstand demanding conditions and extended use. Each coilover assembly is fully rebuildable, providing long-term serviceability and the ability to tune the suspension to your vehicle’s load, gear, or off-road setup.

The GR40 is an all-in-one suspension solution that replaces your stock components with complete coilover assemblies. Its adjustable valving and soft linear rate springs deliver comfort at low speeds and control at high speeds or over rough terrain. This system eliminates the need for spacer lifts or mixed spring/shock combos.
