Detailed Product Overview

INA ZT-9-5442 is part of INA’s timing drive repair solutions for chain and belt components. In the engine valve train, the tensioner helps keep the timing chain properly loaded so the drive system can maintain the correct relationship between the crankshaft and camshafts. That matters for drivability, engine response, and long-term timing system reliability. This part number is used across a wide range of Nissan and INFINITI vehicles, including Nissan Altima, Maxima, Murano, Pathfinder, Quest, and 370Z, as well as INFINITI G37, Q50, Q70, QX50, QX60, and QX70 models.

What It Helps Address

• Timing chain slack or inconsistent chain tension
• Noise from a worn or weakened timing drive tensioner
• Incorrect valve timing caused by timing drive wear
• Service needs on chain-driven Nissan and INFINITI engines
• Replacement of a failed right-side or right upper tensioner assembly

Installation Notes and Tips

Verify engine code, model year, and tensioner position before ordering. Fitment includes right and right upper applications, and some listings reference secondary or thru notes, so confirm the exact engine layout against the vehicle’s service information. Inspect the timing chain, guides, and related valve train components during service to avoid repeat repairs. Part number ZT-9-5442 should be matched to the vehicle application and the INA Global Number 551 0494 100 reference where listed.
