Tired of a trunk lid that won't stay up? The Tuff Support Trunk Lid Lift Support (P/N 611746) is a gas-charged strut that raises the trunk lid and holds it open, and it drops in as a direct-fit replacement for the 2006-2013 Lexus IS250, 2006-2013 Lexus IS350, and 2008-2014 Lexus IS F.
- Does the lifting: The pressurized gas cylinder extends to raise the lid and steadies it overhead so it doesn't drift down while you load and unload.
- Sold individually: The listed Lexus applications use two supports per vehicle (Quantity Per Application: 2), so order 2 to replace both sides together as a matched pair for even, balanced support.
- Signs it may need replacing: a trunk lid that slowly sags shut, won't stay up on its own, or feels weak and slow to raise — often worse in cold weather — are common signs a lift support has lost its charge.
Each unit is a direct-fit replacement for the listed applications. If a worn-out lift support is the reason your trunk won't stay open, this replaces it. Manufacturer part number 611746.
