Description

This master overhaul kit is engineered for Chrysler/AAM 11.5” rear differentials and specifically accommodates vehicles with rear coil springs. A key feature of this kit is the inclusion of conversion bearings that facilitate the installation of an early 2.00 inch diameter pinion, replacing the original factory 2.125 inch diameter pinion. This conversion allows for greater flexibility and compatibility when rebuilding or modifying your differential setup. USA Standard Gear is recognized for offering a wide array of tailor-made kits to suit specific installation needs, ensuring you have the correct components to start and finish every differential job with confidence. This kit is part of their commitment to providing comprehensive solutions for various automotive applications.
