Front Conversion Kit for Lexus RX300

The Unity 31-116000 kit converts the front air suspension on 1999-2003 Lexus RX300 models to a passive steel-spring setup. It is designed for owners who want to eliminate air-ride leaks and compressor failures with a more reliable suspension configuration.

Replaces Factory Air-Spring Components

This kit removes the original air struts, compressor and associated plumbing that often degrade after 31 years of service. The conversion is worth it when recurring air-leak repairs exceed the cost of a one-time steel-spring retrofit.

Limited to 1999-2003 RX300 Front Axle

The kit fits only the front suspension of the specified Lexus RX300 model years and does not address the rear air springs. Vehicles with rear air suspension will retain that system, and the conversion does not apply to other Lexus models or later RX generations.

Questions about this item

Will this front conversion kit bolt onto the factory mounting points of my 1999-2003 Lexus RX300 without modification?

Yes, the kit is engineered specifically for the 1999-2003 Lexus RX300 and uses the original suspension mounting locations for a direct fit.

What is the correct procedure for compressing the coil springs during installation, and what mistake causes uneven ride height?

Use a proper spring compressor on the new coils, tighten the top mount nuts to the vehicle's specified torque only after the vehicle weight is on the suspension, and never reuse the old top hat hardware.

Which components in this conversion kit are wear items that will eventually need replacement?

The coil springs and strut mounts are the primary wear items; inspect them during regular brake or tyre service and replace if sagging, corrosion or noise develops.
