What gear ratios is this Yukon Dura Grip differential compatible with?

This Dura Grip positraction unit is designed to work with 3.73 gear ratios and any numerically lower ratios. It is specifically designed for the 55P GM axle with 17 spline axles.

What makes the Yukon Dura Grip different from an open differential?

An open differential sends power to the wheel with the least traction. A limited-slip differential, like the Dura Grip, automatically biases torque to the wheel with more traction, improving performance and control in slippery conditions or off-road.

Is this differential a direct bolt-in replacement for all 55P GM axles?

This unit is designed for 55P GM axles with 17 spline axles and 3.73 or numerically lower gear ratios. Proper installation may require specific tools and knowledge of drivetrain components. Always refer to the manufacturer's installation instructions or consult a professional mechanic.

Product Details

When you're tackling rough terrain or just want more confidence on the road, a limited-slip differential can make a big difference. This Yukon Dura Grip positraction unit is built to handle demanding conditions, offering smooth yet aggressive traction for a wide range of vehicles. It's designed to work with 3.73 gear ratios and numerically lower, and it's compatible with 17-spline axles found in many classic GM vehicles, including models like the Chevrolet Bel Air, Corvette, and Impala from the mid-50s to mid-60s.

Yukon Gear & Axle put some serious thought into building this unit for the long haul. The case is made from strong nodular iron, and the spider gears are forged from 4320 chromoly steel, which is known for its toughness. It also uses composite clutches that are designed for durability and consistent performance. Because it's completely rebuildable, you can service it down the road to keep it performing at its best. This unit is assembled in the USA after undergoing extensive testing and design work.

Installing a limited-slip differential is a significant upgrade for your drivetrain. It helps ensure that power is sent to both wheels, even when one starts to lose traction. This unit is designed to fit a variety of 55P GM applications with 17-spline axles and 3.73 or numerically lower gear ratios. Make sure to consult your vehicle's service manual or a professional mechanic for specific installation procedures and any additional components you might need.
