Transfer case chain (DCD, ITC DD295)

Common symptoms include a loud clicking or popping noise under heavy acceleration, a jerking sensation when the 4×4 system engages, or a ‘skipping’ feeling. These happen because a stretched chain loses its tension and jumps over the teeth of the internal sprockets.

This chain is specifically designed for the DCD and ITC DD295 transfer case units. These are typically found in various Land Rover and Mercedes-Benz off-road models. To be 100% sure, check if your transfer case tag identifies the model as ITC DD295 or DCD.

In many cases, replacing the chain is a cost-effective way to restore the unit’s functionality without buying a complete assembly. However, you should inspect the sprockets for wear; if the teeth are sharp or damaged, they may cause a new chain to wear prematurely.

The primary causes are high mileage, lack of regular fluid changes, and heavy off-road use. Over time, the metal links stretch slightly, leading to slack that eventually disrupts the smooth power transmission between the front and rear axles.

Replacing the chain requires opening the transfer case housing. While it is a standard part of a rebuild, it requires mechanical expertise and specific tools. We recommend professional installation to ensure the seals are properly seated and the unit is correctly shimmed.
