Lift kit for Lexus RX - Fourth generation | AL20 | 2015-2022

Lift set for Lexus RX - Fourth generation (2015-2022) | Classic Series

Improve the ground clearance and overall capability of your fourth-generation Lexus RX (AL20) for better all-road performance. Raising the vehicle height enhances its approach angles and underbody clearance, making it significantly easier to navigate steep parking ramps, high curbs, deep winter ruts, and unpaved terrain. This polyurethane lift kit gives you the added height to protect your exhaust system and underbody from hidden rocks, while preserving your exact factory suspension settings and ride comfort.

This complete lift kit is specifically engineered for:

Years: 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022

☑️ Full Compatibility: This lift kit is 100% compatible with all fourth-generation Lexus RX model variants. It seamlessly fits all factory versions — including RX200t, RX300, RX350, RX350L, RX450h, and RX450hL — across all trim levels, drivetrain configurations (Front-Wheel Drive and All-Wheel Drive E-Four), and all powertrain options (including petrol and hybrid variants) produced from 09.2015–11.2022.

⚠️ AVS Notice: Premium trim levels and performance variants (such as F Sport and Luxury) are frequently factory-equipped with the AVS (Adaptive Variable Suspension) system. While this lift kit is physically 100% compatible with AVS dampers, it requires mandatory mechanical sensor height adjustment and a Zero Point Calibration using a diagnostic scanner post-installation. If you or your workshop are not prepared to perform these complex suspension sensor configurations, this lift kit is NOT recommended for your vehicle. Skipping this step will lead to setup difficulties, incorrect adaptive damping behavior, and chassis control system errors.

• Front Axle Installation (Studs): This kit requires pressing out the original factory splined studs from the front upper strut mounts. They must be replaced with the provided reinforced extended studs to ensure sufficient thread engagement and maximum structural integrity.
• Note on Rear Spacer Design: To achieve the stated +40mm of actual lift, the physical thickness of the rear spacers is calculated to include the height of the original factory spring pads. By integrating these measurements, we ensure a precise fit and the exact lift height promised, regardless of the thickness of your old, worn-out factory isolators.
• Installation Note (Rear Axle): Important: The factory rubber spring isolators (gaskets) must be removed before installing the new spacers. Our spacers are designed to replace the factory isolators entirely, not to be installed on top of them.
• Lift Height Disclaimer: Please note that the final achieved lift height may vary depending on the individual condition and service life of your vehicle's suspension. Factors such as factory spring fatigue, engine and powertrain weight configurations (standard 2.0L Turbo / 3.5L V6 petrol vs. significantly heavier Hybrid AWD systems with battery packs on RX450h/RX450hL), as well as long-wheelbase 7-seater body variants (RX350L/RX450hL), can influence the final suspension height.

Our spacers are manufactured from professional-grade Polyurethane SCU-PFL-100 (93A Shore hardness). This material is the core of our Classic line, offering distinct advantages:

• Comfort & Quiet:

  Unlike metal spacers, polyurethane effectively absorbs road vibrations, maintaining high ride comfort and reducing suspension noise.

• Stealth Appearance:

  ⚫ The solid classic black color of the polyurethane ensures that the spacers remain invisible under the wheel arches and look like original equipment.

• Extreme Durability:

  100% resistant to road salt, oils, and harsh weather conditions. Polyurethane never rusts or corrodes, making it ideal for both snowy regions and coastal areas with high humidity.

• Structural Integrity:

  The 93A hardness ensures the spacers hold their shape even under heavy loads, while remaining flexible enough to protect your suspension.

• Wheel Alignment: A professional wheel alignment is required after installing the lift kit. This is a mandatory step to ensure proper handling and to keep your tires wearing evenly.
• Self-Installation: A spring compressor is required for installation. Please ensure you have the proper tools if you plan to install the kit yourself.
• Professional Installation: For your safety and the best results, we recommend having this kit installed by a qualified mechanic or a suspension specialist.

While this kit is for +40mm, we offer various heights of spacers to help you build the perfect lift kit for your needs. You can combine different heights to compensate for rear-end sag or to achieve a specific custom stance for your vehicle.
