• Wear in NP241 transfer case components on Chevrolet and GMC 4x4 models

Installation Notes and Tips

Verify the transfer case is NP241 and confirm the unit uses the BD50-8 input bearing before ordering. Match the bearing type and dimensions to the original components during teardown, and inspect the case, shafts, and sealing surfaces for wear before assembly. This kit is listed for N/A position applications and should be installed according to the vehicle and transfer case service procedure.

SKF manufactures these kits to meet or exceed original equipment specifications, with components selected for long service life and dependable sealing performance. The STCK241 is built for complete repair coverage on the listed applications, helping reduce repeat service on the same transfer case.
