Dorman 697-800 Differential Carrier - Rear

Dorman 697-800 Limited-Slip Differential Carrier

Dorman 697-800 is a replacement limited-slip differential carrier assembly for rear axle applications that need restored traction and smooth power transfer. It addresses wear from hard use and poor lubrication by replacing the carrier housing, spider gears, differential pins, and clutches with all-new components.

Compatible With Chevrolet Silverado, Tahoe, GMC Sierra, Yukon, and other rear differential applications listed below, this cast iron carrier is built for 28-spline setups and common GM axle configurations.

Key Features

• Limited-slip differential carrier assembly for rear axle service
• Cast iron construction for strength and durability
• 28 axle shaft spline quantity
• Includes new spider gears, differential pins, clutches, and carrier housing
• Direct replacement for worn limited-slip differential components
• Cross-reference part numbers include 742G715D and 25824246

Detailed Description

This Dorman differential carrier is built to restore original limited-slip operation when the factory unit has worn out from mileage, load, or lubrication breakdown. The assembly is intended for rear differential service and is listed across a wide range of GM trucks, SUVs, vans, and performance cars, including Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications. Part number 697-800 is a practical replacement when the carrier housing and internal limited-slip components are no longer performing as they should.

The cast iron housing provides a solid foundation for the internal gearset, while the new clutches and spider gears help recover consistent torque transfer between the axle shafts. This makes 697-800 a strong match for rear-end rebuilds on vehicles with 28-spline axles and the specified ring gear and axle ratio combinations.

What It Helps Fix

• Chatter, slipping, or inconsistent limited-slip action
• Worn spider gears or differential pins
• Loss of traction from degraded clutch packs
• Noisy or rough rear differential operation
• Carrier wear caused by poor lubrication or heavy-duty use
