Yukon Gear High Performance Thick Gear Set For GM 12 Bolt Car in a 4.11 Ratio

What you get here is a high-performance, thick ring and pinion gear set from Yukon Gear & Axle, specifically designed for GM 12-bolt car differentials with a 4.11 gear ratio. This set includes the ring gear and the pinion gear, both crafted from high-grade steel. This is a substantial upgrade for vehicles like the Chevrolet Chevelle, Pontiac GTO, or Buick Wildcat, especially if you've added more horsepower or larger tires. The 4.11 ratio is a popular choice for balancing acceleration and highway cruising, making it a versatile option for many builds.

Yukon engineers put a lot of thought into these gears. They've focused on the tooth surface finish to cut down on friction and heat, which is crucial for long races or when you're putting down serious torque. This attention to detail means the gears are built to last and perform consistently, even under demanding conditions. The fitment is designed to OEM specifications, meaning it should install right into your GM 12-bolt carrier without major modifications, though professional installation is recommended for this type of drivetrain component. The "thick" designation means this set is intended for carriers designed for 3.90 and numerically lower ratios, ensuring proper meshing and strength.

Beyond the gears themselves, Yukon Gear & Axle stands behind their product with a 1-year warranty against manufacturing defects. They also offer an optional Y.E.S. Plan for lifetime coverage, giving you extra peace of mind. When you're ready to put down serious power, this Yukon gear set is a solid choice for your GM 12-bolt differential.
