Eibach Load-Leveling System for 2003–2009 Lexus GX470, 400+ lb Load Rating – AK31-59-005-03-02

The Eibach Load-Leveling kit is optimal for vehicles which are frequently loaded and unloaded for towing, camping trips, or overland expeditions. Armor, roof-top tents, storage shelving, full size spares and tire carriers increase weight ultimately effecting static ride height of your vehicle. The addition of the height adjustable perch allows fine tuning of rear ride heights, keeping your chassis clear from the trail, and tires clear from fenders. Height Adjustable Rear Spring from 2.0" to 3.5" with 400lbs of added rear weight.

• Adjustable Threaded Spring Seat, ERO Race Springs and Bump Stops allow fine tuning of Rear Load Capacity and Ride Height
• Eibach ERO Off-Road Race Spring Compatible for Adaptability
• 6061-T6 Billet Aluminum Threaded Spring Seat
• For vehicles with 400LBS of Added Weight.
• Made in the U.S.A.

The Eibach Load-Leveling System is designed for 2003–2009 Lexus GX470 vehicles that regularly carry additional equipment or cargo for towing, camping, overland travel, or off-road use. Added armor, roof-top tents, storage systems, full-size spare tires, and tire carriers can lower the vehicle’s static rear ride height and reduce available chassis and tire clearance.

Using an adjustable threaded spring seat, Eibach ERO off-road race springs, and bump stops, this system allows the rear suspension to be fine-tuned for vehicles carrying approximately 400 pounds of additional rear weight. The height-adjustable rear spring supports adjustment from 2.0 to 3.5 inches, helping maintain a practical ride height and improved clearance under changing load conditions. The 6061-T6 billet aluminum threaded spring seat provides durable, precise adjustment for demanding off-road applications.

Part number AK31-59-005-03-02 is made in the USA and is compatible with Eibach ERO off-road race springs for added setup flexibility. This automotive suspension system is intended for GX470 owners seeking a more adaptable rear load-support solution without relying on a fixed-height spring configuration. Professional installation and appropriate suspension setup are recommended.
