Description

The USA Standard ZG D44-513T-RUB is a replacement ring and pinion set engineered for standard rotation Dana Spicer 44 axles, with a specific application for the TJ Rubicon model. This set provides a 5.13 gear ratio, ideal for optimizing performance with larger tires or for heavy-duty applications. It is designed as a 'thick' gear set, compatible with carriers originally intended for 3.73 and numerically lower ratios. Key specifications include 26 splines, 10 ring gear bolts, and an 8.50-inch ring gear diameter. USA Standard Gear backs their ring and pinion sets with a standard one-year warranty against manufacturing defects. Customers can expect a direct fit for the specified Dana 44 TJ Rubicon axles, ensuring straightforward installation for those looking to re-gear their differential. Free ground shipping is offered to the lower 48 states, with expedited options available at checkout.
