Stabilus SG229040 Lift-O-Mat Gas Charged Liftgate Lift Support

The Stabilus SG229040 is a gas-charged lift support from Stabilus's industry-leading Lift-O-Mat line, engineered to restore and maintain the smooth, controlled operation of your vehicle's trunk lid or liftgate. Designed as a direct OE replacement, this lift support is built to the same performance standards as the original equipment it replaces.

Lift-O-Mat technology utilizes a longitudinal velocity manifold groove pressed into the tube wall, allowing gas to flow around the piston with precision-tuned extension speed and dynamic damping. This gas-based approach delivers smooth, fluid motion — eliminating the bouncing or jerking common with worn or failed supports. The groove profile gradually narrows toward the end of the stroke, ensuring a gentle, controlled stop every time.

Key Features:

• Gas-charged Lift-O-Mat design with dynamic damping speed control for fluid, controlled opening
• Velocity manifold groove technology precisely tunes extension speed for this specific application
• Integrated rust-resistant piston rod for extended service life
• Part coatings tested to automotive standards for corrosion resistance
• Engineered to OE fit, form, and function — a true direct replacement
• Rated for consistent lifting force through 50,000 cycles
• Tool-free installation — no special tools required

For best results, replace lift supports in pairs to ensure balanced, even operation. The Stabilus SG229040 is a maintenance-free solution that restores the original opening and closing performance of your trunk lid or liftgate.
