This kit replaces the original Automatic Height Control (AHC) suspension on Toyota LandCruiser 100 Series models with a conventional coil spring and torsion bar system. It is designed for heavy duty load carrying and towing, providing a cost-effective and reliable alternative to AHC repairs.

Key Features

• Complete kit for AHC system removal
• Cost-effective alternative to AHC repairs
• Integrated components engineered to work together
• Variants tailored for different vehicle uses
• Backed by a 2-Year / 25,000-Mile Warranty

Product Overview

The kit converts the complex hydraulic AHC system, which can develop faults over time, to a more straightforward mechanical suspension arrangement. It includes front torsion bars, reinforced mounting plates, rear coil springs, and shock absorbers all around. This makes it suitable for frequent heavy loads and towing, delivering firm ride comfort when unladen but improved reliability under demanding use.

Several kit variants offer different ride heights and heavy-duty features, allowing selection based on load and clearance needs. The conversion is designed for the HD FZJ and UZJ100 IFS platforms of the LandCruiser 100 Series and fits all wheel sizes despite height measurements being referenced with 16-inch wheels.

Technology & Materials

The kit replaces the hydraulic and pressure sphere based AHC system with conventional mechanical suspension components. This includes coil springs and torsion bars engineered for heavy duty use, combined with matching shock absorbers and reinforced mounting hardware to ensure durability and consistent performance.

Installation & Compatibility

The kit includes all components required to fully disable the AHC system and install the coil springs, torsion bars, and shocks. It is designed as a bolt-in replacement for the existing suspension without modifying the vehicle structure. It is recommended to perform a professional wheel alignment after installation.

This kit is suitable for drivers needing a durable suspension solution for heavy loads and towing, especially where the original AHC system may have faults.
