| This factory pilot bushing fits all 4 and 6 cylinder L series engines, Naps/Z 4 cylinder engines, both 1600 and 2000 roadster engines, as well as the VG30 engines in the 84-89 300 zx. We've found these bushings to be superior to most of the aftermarket units available. You should always replace the pilot bushing when doing a clutch job. For all the 6 cylinder engines as well as the L4's and the Naps/z engines, we always recommend replacing the rear crank seal at the same time. See listing. Last update 12/10 |
