NP1128F Transfer Case Slip Yoke

This is the NP1128F transfer case that we use behind the 6R140 transmissions found in the 2015-2019 V10s and 2021/up 7.3 gas vans. This is a bolt up unit for the E450s and most of the V10 E350s. 2021/up E350 7.3s need a new output shaft before this t-case can be used. Email chris@ujointoffroad.com if you need help ID'ing what you have.
