Application Details

This liftgate support is used on Lexus RX vehicles where the rear liftgate needs controlled opening and holding force. For 2008-2009 Lexus RX350 and 2004-2006 Lexus RX330 applications, the listing notes specific bracket requirements and, for RX330, a non-power configuration. Use 612190 when matching the exact vehicle year, model, and notes shown in the fitment data.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Problems It Can Address

• Liftgate that will not stay open
• Rear hatch that drops too quickly
• Weak or inconsistent lift support pressure
• Difficulty opening or holding the liftgate in place
• Wear-related loss of hatch support on Lexus RX models

Installation Notes

Verify the vehicle year, model, and configuration before ordering. Match the fitment notes exactly: 2008-2009 RX350 is listed as supplied with brackets, while 2004-2006 RX330 is listed without power and with brackets. Compare the existing lift support and mounting points to confirm the correct application before installation.

Quality Assurance

Tuff Support is owned by ISC Industries, a lift support manufacturer based in Turkey. That manufacturing background supports consistent application-specific replacement parts for rear liftgate service.
