Detailed Description

Stabilus 4B-197439 is an OE-style gas spring specified for Infiniti lift support service on the 2010-2013 Infiniti G37 and 2014-2015 Infiniti Q60. The unit’s 340 N force rating, 295.5 mm compressed length, and 471.5 mm extended length are the core dimensions used to match the original support geometry and operating effort. The plastic socket attachment style on both ends supports a direct-fit replacement where the original design uses socket-mounted connections.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Stabilus 4B-197439 is also referenced under part number 4B-197439 for catalog and search matching.
