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 /help-center/he-05130-what-are-the-different-shipping-options-costs-and-transit-times and /core-return before checkout

Can I buy a transfer case without an engine?

Do install kits fit every engine?

Kits are SKU-specific; confirm variant codes with a specialist.

Is additional oil required?
