Description

The Revolution Gear and Axle 75-2023-40 is a full spool differential designed for GM 14-bolt 10.5-inch axles. It features 40 spline count and is compatible with 4.10 gear ratios and numerically lower (e.g., 3.73, 3.55). This spool provides 100% traction to both wheels simultaneously. It is a cost-effective option for racing or off-road applications.

Spools are not recommended for daily driving due to the added stress they place on the drivetrain. This component is manufactured in India.
