Detailed Description

INA ZS-S861 is an engine timing crankshaft sprocket designed for vehicles that rely on precise crankshaft-to-camshaft timing. This sprocket is used in timing system repairs on applications such as 2000-2010 Dodge Dakota, 1999-2010 Jeep Grand Cherokee, and 2011-2013 Ram 1500.

What It Helps Address

• Worn or damaged crankshaft sprocket teeth
• Timing chain drive noise caused by sprocket wear
• Incorrect cam/crank synchronization from timing component deterioration
• Service replacement during timing chain or engine front-end repairs
• Restoration of proper timing system engagement on Chrysler, Dodge, Jeep, Ram, and Mitsubishi engines

Installation Notes and Tips

Verify engine code, timing system layout, and OE part match before installation. Because fitment varies by model year and engine configuration, confirm the vehicle against the listed applications for Dodge Dakota, Jeep Liberty, Dodge Nitro, Ram Dakota, and Jeep Commander. Inspect related timing components, including the chain, guides, and tensioner, during service to avoid repeat repairs.
