Did you mess up the retaining nut while changing out a pulley? Did you drop it and lose it in the abyss? Do you have a custom bracket or setup that might need some slight pulley alignment correction to get that perfect laser aligned belt path? Say no more, we have you covered.
These are the same Denso spec'd flange nut and shims we use on all of our Denso based alternators with the 17mm rotor shaft diameter's.
Always ensure there is enough rotor thread available for secure fitment! Failure to have full pulley nut thread engagement can lead to rotor thread damage and/or catastrophic failure of belt system.
