Product Details

The Yukon Gear & Axle ZG C9.25B-355B is a USA Standard ring and pinion gear set designed specifically for 2011 and newer Chrysler 9.25" ZF rear differentials with a 3.55:1 gear ratio. This precision-engineered gear set provides a direct replacement for worn or damaged factory gears, restoring optimal differential performance and driveline efficiency.

Key Features:

  • 3.55:1 gear ratio for balanced performance and fuel economy
  • Precision-manufactured to OE specifications for proper fit and quiet operation
  • Heat-treated alloy steel construction for maximum strength and durability
  • Designed for Chrysler 9.25" ZF axles in 2011+ Ram trucks and other Chrysler vehicles
  • USA Standard Gear quality backed by Yukon's industry-leading warranty

Professional installation is required, including proper setup with new bearings, seals, and a master install kit (sold separately). Ring and pinion gears must be installed as a matched set and require precise backlash and bearing preload adjustment for optimal performance and longevity.

I ordered adapters for my current 5th wheel hitch unfortunately they are the incorrect adapters would like to return just waiting on response from autoplicity regarding return.

We had a few questions. Like how to pay with Amazon which didn't come up. Also we live in a small town. We put in the home address and added the PO Box Number since our town is too small for home delivery. But mostly we negotiated it ok.

Called the returns dept and found a friendly helpful person to answer my questions! how refreshing

Excellent Service! Excellent Prices!!

did not see if delivery would be Wed July 22?
