Timing Wrench

This handy wrench is specially designed to turn the crankshaft pulley large nut when adjusting valve timing or setting valve lash. For Spec Miata Racers, it is handy in the tech shed when having compression tested by way of a "Whistler".

Most standard socket and racket combinations will not clear the front sway bar. While just a wrench gives poor grip on the pulley bolt. The Advanced Autosports timing wrench fits perfectly on all model years from 1990-2005 and both 1.6 and 1.8 engines.
