Transfer Case and Install Kit Buying Guide for Drivetrain Swaps
When you need a transfer case (TC) or install kit (IK) with your engine or transmission order — SKU segments, fitment, and bundle tips on Expedia Parts.
Transfer case (TC segment)
Transfer cases route power to front and rear axles on 4WD and AWD applications. Match:
- OEM tag and ratio
- Year, make, model, and engine family
- Connector and speed sensor count
Reman TC SK
Us use the **R** segment; used LKQ tiers use **UB/UO/UM** when offered.
Install kit (IK segment)
Install kits bundle hardware, fluids, and gaskets for professional installation. **IK** rows in our catalog are reman-class (**R** segment) add-ons — pair them with the engine or transmission SKU you are installing.
Order workflow
1. Confirm main unit fitment (engine **E** or transmission **T**) 2. Add matching **TC** if 4WD/AWD 3. Add **IK** for shop install 4. Review /shipping-policy and /core-return before checkout
