Description

The GMC GT5-G80 is a rear axle assembly featuring a 4.10 gear ratio and a G80 locking differential. This combination is often found in Chevrolet and GMC trucks and SUVs. The GT5 RPO code indicates the 4.10 gearing, while the G80 code signifies the automatic locking rear differential.

This assembly is compatible with various Chevrolet and GMC models, including Silverado, Sierra, C2500, and 3500 HD Dually trucks, as well as Suburban 2500 and Yukon. Specific model year fitment varies, with applications noted for 1988-2000 C2500, 2001-2006 3500 HD Dually, and potentially other GM trucks from those eras.
