Unity Rear Conversion Kit 31-516200-FWD for AWD

This Unity rear conversion kit converts the air suspension on AWD Lexus RX models to a passive coil-spring setup. It fits 2004 to 2006 RX330, 2007 RX350 and 2006 to 2007 RX400h vehicles. The kit supplies preassembled strut assemblies with top mounts, bearing plates, bumpers, insulators and coil springs. All components are new and designed for a direct, bolt-on installation.

Who this suits and who should look elsewhere

The kit suits owners of compatible AWD Lexus RX models who want to eliminate air-suspension maintenance with a reliable passive system. It is not for front-wheel-drive variants of these vehicles. It does not fit models outside the 2004 to 2007 range or other Lexus lines. Buyers needing to retain the original air-ride function should not use this conversion kit.

AWD-only fitment for 2004-2007 Lexus RX models

The single deciding specification is that this conversion kit fits all-wheel-drive Lexus RX330, RX350 and RX400h models produced between 2004 and 2007. Front-wheel-drive versions are excluded. Verifying the drivetrain and model year against this fitment list confirms whether the kit is the correct part for the vehicle.

Questions about this item

Does the kit ship as a complete unit or do I need to buy any extra hardware for my 2004-2006 Lexus RX330?

The kit arrives as preassembled strut assemblies including top mounts, bearing plates, bumpers, insulators and coil springs, so no additional components are required for installation.

Is the 31-516200-FWD kit the correct choice for a 2007 Lexus RX350 with all-wheel drive?

Yes, the conversion kit is listed for AWD only and covers the 2007 Lexus RX350 along with the 2004-2006 RX330 and 2006-2007 RX400h models.

What does the preassembled strut assembly actually replace on the vehicle once fitted?

It replaces the original air-spring strut with a passive coil-spring unit, eliminating the air-ride system while using OE-style mounting points for a direct fit.
