Stabilus 3B-059571 Lift-O-Mat Liftgate Lift Support Gas Spring with Temperature Compensating Valve

The Stabilus 3B-059571 is a Lift-O-Mat liftgate lift support gas spring designed for vehicles without a power liftgate. Engineered to OE specifications, this gas-charged lift support delivers smooth, controlled motion when opening and holding liftgates, tailgates, hoods, and hatches in place.

Lift-O-Mat Dynamic Damping Technology:

Unlike conventional lift supports that rely on an oil column, the Lift-O-Mat uses a precision-machined longitudinal groove—called a velocity manifold—pressed into the tube wall. This allows gas to flow around the piston in a controlled manner, with the groove's depth and geometry precisely regulating extension speed for a smooth, fluid opening motion with no bouncing or jerking.

The groove gradually narrows toward the end of the stroke, delivering a gentle, cushioned stop with minimal impact force.

Temperature Compensating Valve (TCV):

This unit includes an integrated Temperature Compensating Valve managed by a temperature-sensitive bi-metal valve inside the tube. In cold weather, the valve releases additional gas force to maintain proper hold strength. In warm conditions, it locks away excess force to prevent over-extension and ensure stability.

Key Features:

• Stabilus Lift-O-Mat gas spring with dynamic damping speed control
• Temperature Compensating Valve (TCV) for consistent performance in all weather conditions
• Velocity manifold groove design for smooth, jerk-free liftgate operation
• Cushioned end-of-stroke stop minimizes impact
• Designed for vehicles without power liftgate systems
• OE-level fit, form, and function
• Sold individually — quantity of 2 required per vehicle

The Stabilus 3B-059571 is built from high-quality materials and engineered for long-term durability, making it a reliable direct replacement for worn or failed OEM lift supports.
