Revolution Gear & Axle Ring & Pinion Set for GM 10.5" 14-Bolt Rear Axle (4.10 Ratio)

This Revolution Gear and Axle ring and pinion set is a 4.10 ratio gear for the GM 10.5 inch 14-bolt rear axle, the heavy-duty rear found under GM 2500 and 3500 trucks. It is a common ratio for towing and larger tires.

The set uses a 30-spline pinion and a 10.5 inch ring gear built for the 14-bolt housing, made from 8620 steel and heat treated to OE-level standards, then lapped for quiet running. Note the carrier break: this gear family splits at 4.10/4.56, so verify your carrier supports a 4.10 before ordering.

A 4.10 ratio is a workhorse choice for heavy GM trucks that tow or run taller tires, giving back low-end pulling power without an extreme drop in highway gearing.

This is a gear set only. It does not include bearings, an install kit or a limited slip/locker. Plan on the matching Revolution GM 14-bolt 10.5 master install kit for your year range and have an experienced installer set pinion depth, backlash and preload to spec.

For a 14-bolt that needs fresh gears or a tow-friendly ratio, a 4.10 ring and pinion is an OE-quality, durable choice.
