Stabilus 3B-5399SL Hood Lift Support

Hood Lift Support for Controlled Opening

The Stabilus 3B-5399SL hood lift support is a gas-charged Lift-O-Mat unit built for smooth, controlled hood movement. It uses dynamic damping to slow the final part of the stroke for a gentle stop, making it a precise OE-style replacement for applications that require refined motion control.

Fits application-specific hood support setups for light truck and car use, including select Honda Civic and Toyota Corolla fitments where this part number is specified.

• Application-specific design for OE-style motion control

Detailed Description

Stabilus 3B-5399SL is a hood lift support engineered with Lift-O-Mat dynamic damping technology. Instead of relying on basic damping behavior, the internal gas flow is managed through a precision groove profile in the tube wall, helping the hood slow progressively near the end of travel. That controlled motion is useful where a smooth, consistent hood opening feel is required. This part cross-references Monroe Shocks & Struts 172286 for the same application.

For buyers searching for a hood lift support for Honda Civic or Toyota Corolla, this Stabilus unit provides the dimensions and mounting style needed for application-specific replacement work. The 3B-5399SL part number is also referenced as 5399SL in interchange listings, which can help when verifying the correct hood strut for a vehicle repair.

What It Helps Fix

• Hood that drops instead of staying open
• Slow or uneven hood lift action
• Hood that closes too quickly
• Loss of support from a worn gas strut
• Inconsistent hood movement during service access

Installation Notes and Tips

Verify compressed length, extended length, stroke, and ball socket end style before installation. Compare the original hood lift support to the 3B-5399SL part number and confirm the mounting points match the vehicle’s existing hardware. Because mounting hardware is not listed as included, reuse or replace only the components already specified for the application.

For fitment-based searches, this hood lift support is commonly referenced for select Honda Civic and Toyota Corolla applications. Confirm the exact year, model, and position against the vehicle catalog before ordering.

Quality Assurance

Stabilus is known for OE-focused gas spring and lift support engineering, and the Lift-O-Mat line is built around controlled motion and consistent damping behavior. The 3B-5399SL is manufactured to support precise hood operation in application-specific automotive use.
