What is the benefit of a 4.56 gear ratio?

A 4.56 gear ratio generally provides more torque multiplication, which is beneficial for towing heavier loads or for vehicles equipped with larger tires. It helps bring the engine's RPMs back into a more efficient range after modifications.

Does this ring and pinion set come with installation hardware?

This product is a ring and pinion gear set only. Installation typically requires additional components such as bearings, seals, and installation kits, which are sold separately. Refer to the manufacturer's installation guide for a complete list of required parts.

What is the break-in procedure for new ring and pinion gears?

Proper break-in is crucial for the longevity of new gears. It generally involves a period of moderate driving, avoiding hard acceleration or heavy loads, and performing several short cool-down drives. Always consult the manufacturer's specific break-in procedure instructions.

Product Details

If you're looking to change your vehicle's gearing for better towing or off-road performance, a new ring and pinion set is a key component. This USA Standard Gear set is designed for GM 11.5-inch rear axles and features a 4.56 ratio. This ratio is a popular choice for those who have added larger tires and need to bring the engine back into its optimal RPM range, or for heavy towing applications where more torque multiplication is beneficial.

Yukon Gear & Axle's USA Standard line is built to meet or exceed original equipment manufacturer specifications. Each set undergoes strict in-house quality checks, including dimensional, material, and fitment testing, ensuring you get a well-built part that performs reliably. This 4.56 ratio set is a solid option for trucks like the Chevrolet Silverado 2500 HD, GMC Sierra 3500 HD, and Dodge Ram 2500, among many others in the GM 11.5-inch axle family.

Changing your gear ratio is a significant modification that requires precision installation. While this set is designed for a direct fit into the specified GM 11.5-inch axle housings, it's crucial to follow the manufacturer's installation instructions carefully, which typically involve setting backlash, gear pattern, and proper break-in procedures. This ensures the longevity and performance of your new gears.
