Raise and hold your hood with a smooth, controlled motion using the Stabilus Hood Lift Support 4B-431885, a gas-charged lift support with dynamic speed control that measures 20.20 inches. It drops in as a direct-fit replacement for the 2010-2015 Lexus RX350 and 2010-2015 Lexus RX450h — see the "Vehicles it fits" section for engine-level details.
Built around Stabilus Lift-O-Mat with Dynamic Damping, it uses a longitudinal groove pressed into the tube wall — a velocity manifold — that lets gas flow around the piston with extension speed and damping engineered for this application. The groove profile gradually narrows toward the end of the stroke for a gentle, controlled stop.
- Dynamic damping control: creates a fluid opening motion with no bouncing or jerking during cycling.
- OE-based design: based on the OE design to help ensure proper fit, form and function.
- Corrosion-tested coatings: part coatings tested to automotive standards for corrosion resistance.
- Easy installation: installs with no special tools.
For best results, replace lift supports in pairs.
