Cummins Main Bearing Kit 3801260

These replacement engine bearings are manufactured with high grade materials, featuring tri-metal construction for heavy-duty durability. Interstate-McBee's commitment to quality is priority number one.

These Interstate-McBee replacement parts are compatible with NT/N14 engine applications. The NT series was first introduced in the 1950s which evolved to become the N14 1980s, a more advanced, electronically controlled version. The N14 features improved fuel efficiency, emissions controls, and horsepower, making it popular for trucks and industrial machinery. Known for its robust design and reliability, the N14 became one of Cummins'® most successful engines for on-highway and off-highway use.
