Product Description

The Yukon Gear & Axle YG GM14T-538T is a high-performance "thick" ring and pinion gear set engineered for GM 10.5-inch 14-bolt full-float rear axles in Chevy and GMC heavy-duty trucks and vans. With a 5.38:1 ratio, it's ideal for enhancing towing capacity and low-end torque while performing under demanding loads. The thick design supports applications with 4.10 and lower carriers for added durability.

Constructed from forged 8620 alloy steel with precision tooth profiles, this gear set provides smooth, quiet operation with reduced heat and wear. Designed to OEM specifications, it ensures direct-fit installation in models spanning from the early C/K trucks of the 1970s to 2015 Express vans and Silverado/Sierra 3500 HD models. Excellent for street, off-road, or heavy-duty towing setups.

Yukon offers a comprehensive one-year warranty and a lifetime Y.E.S. protection plan option for added peace of mind. Please verify your carrier type (thick vs thin) and spline count before installation. Note: mounting hardware not included.
