Description

USA Standard Gear ensures superior performance through rigorous in-house quality evaluations, guaranteeing that each product passes stringent dimensional, material, and fitment testing. This meticulous process results in a reliable and durable component for your drivetrain. The ZG GM9.5-411 features a 9.50-inch ring gear diameter, a 30-spline pinion, and 12 ring gear bolts, providing precise engagement and power transfer. The 4.11 ratio is ideal for applications requiring a balance between acceleration and cruising efficiency. This gear set is compatible with GM 9.5" axles. While specific vehicle fitment can be confirmed through the 'Select Vehicle' tool, the general application is for GM vehicles utilizing the 9.5-inch axle differential. For detailed fitment information or assistance with your specific build project, USA Standard Gear offers technical support via phone at 1-800-347-1188 or live chat.
