Dan the Gear Man Tech® Note 1:
Contrary to popular belief, the Drive Chain can not cause a clunk or contribute to "slack" in the drive train in 4x2 mode. The chain is only under power in 4x4 mode.

Dan the Gear Man Tech® Note 2:
In addition to having the correct length, width, and link height, a replacement transfer case drive chain must have the same type of link pins as the original equipment chain. Why? Because transfer case sprocket teeth are machined with specific features and angles that match a specific link and pin type. Our QU50255 chains exactly match the original equipment specifications because they ARE original equipment chains.

Dan the Gear Man Tech® Note 3:
When Ford (1999 models) and Dodge (2003 models) first used NV271 and NV273 transfer cases, New Process Gear (NPG) of East Syracuse N.Y was part of New Venture Gear (NVG). When NVG dissolved, NPG continued on under Chyrsler. Chyrsler subsequently sold the production rights to Magna, a Canadian automotive parts company. All these name changes are confusing, but the important thing to know is a specific assembly number for any 271F, 271D, 273D, and 273F transfer case is the same and uses the same replacement parts regardless if it was built by New Venture, New Process, or Magna.
