Air Lift Performance Lexus LS400 Rear Kit

This Air Lift Performance suspension component is the Lexus LS400 Rear Kit. Confirm the complete chassis, drivetrain, factory damper or electronic-suspension equipment, front or rear position, ride-height range, wheel and tire clearance, management requirements, alignment needs, and included hardware before ordering.

Key Features

• The designers thought of almost everything to make the vehicle the perfect flagship for the brand, but Air Lift Performance thought that a change in ride height was in order.
• The rear kit features our double-bellow air springs, providing the ability to air out 4.9in from stock.
• The threaded-body shocks allow for up to 30 levels of adjustability, creating an air suspension that is completely customizable for your ideal performance setup as well as your daily driving needs.
• The Lexus LS400 was a five-year, one-billion dollar investment for Toyota, designed to be the absolute epitome of luxury, complete with automatic features, California walnut in the interior, and even an integrated cellular phone.
• Our kits are also about giving you the ability to achieve the versatility that the common coilover cannot provide, eliminating classic lowered-car problems, such as bottoming out, with the touch of a button.

Frequently Asked Questions

Will Air Lift 78659, the Lexus LS400 Rear Kit, work with my factory suspension options?
Confirm the complete chassis, drivetrain, adaptive or electronic dampers, front or rear position, wheel and tire package, and every exclusion for the exact part number.

Does this Air Lift Performance part include air management?
Suspension hardware and management are often sold separately. Check the exact included-parts list before planning compressors, tank, manifold, controller, sensors, lines, and fittings.

Will the vehicle need an alignment after installation?
Yes, a professional alignment is required after ride height or suspension geometry changes. Recheck clearance and alignment at the intended driving height.

Can the vehicle be driven at its lowest display height?
Use only manufacturer-approved driving heights and pressure ranges. A show or aired-out position may not provide safe suspension travel, steering clearance, or tire clearance.
