Upgrade your GM 14-bolt with a 10.5" Thick Ring and Pinion Gear Set designed specifically for 4.11 and down carrier applications. This gear set allows you to run deeper gear ratios without changing carriers, making it a smart solution for builds running larger tires or needing improved torque multiplication.
Designed for GM full-size truck axles, this thick gear allows deeper gear ratios to be installed on a carrier originally designed for 4.11 and numerically lower gears without requiring a carrier replacement.This thick gear set is specifically designed to work with 4.11 and down carriers, and you do not need to purchase a new carrier when upgrading to deeper gear ratios.
