High sealing stagger gap total seal piston ring for GT/GTB 15-25 turbine end application. Will directly replace the original item but with better sealing capability. If the turbo has failed and damaged the bore of the bearing housing, or the side walls of the grooves on the shaft, these should be replaced also. Simply replacing the seal(s) will not provide a complete repair.
If you need a complete repair kit check out the Rebuild Kits section.
