Unity 65190c Rear Conversion Kit for 1990-2000 Lexus LS400

Rear Conversion Kit for 1990-2000 Lexus LS400

This rear conversion kit replaces the original air suspension on 1990-2000 Lexus LS400 models with a passive steel spring setup. It is intended for owners who want to eliminate air ride leaks and compressor failures. The kit provides a direct retrofit solution for the rear axle. It is not for buyers who want to keep the factory air ride system or who need a front axle conversion.

Steel Spring Retrofit With Direct Fitment

The kit uses steel springs engineered to match the vehicle's original mounting points for a trouble-free installation. Unity's 50 years of aftermarket manufacturing experience informs the build quality, aiming for long-lasting reliability without air bags or compressors. The passive design removes the complexity of electronic height sensors and air lines. Daily driving returns a consistent ride height without the risk of overnight sag or warning lights.

Hardware Included For Complete Rear Swap

Bundled hardware covers the components required to complete the rear conversion in one job. Having all brackets and fasteners in the box reduces trips to the parts store and speeds up the installation. The package focuses on the rear axle only, so a separate kit is required for the front. It is not for shops or DIYers looking for a full four-corner conversion in a single box.
