The GKTECH stainless steel turbo locking tabs are critical in keeping your turbo nuts in their place and stopping them from coming loose. The factory items are typically damaged from the heat of the turbo after a number of years so it's a good idea when you've got the turbo off, to replace these at the same time. Simply bend up the ends of the tabs against the turbo nuts to keep them in their place. - Alternative for Nissan part 14495-40P10 - Fits all T2 flanged turbo applications (ie. T25, T28, GT2871r etc. etc.) NOTE: Sold as a PAIR
