here is a 2nd gear synchronizer set with sleeve, 1st/2nd syncrhos and gears for countershaft side only removed from a 2005 civic si ep3 k20 transmission. excellent condition with no damage. this is only for 2002-2005 civic si with k20 engine. this item is not the same for any other k series since the gear ratios are different. this set came from a 99k mile, unmodified SI with case damage from wreck. synchronizers are in excellent condition with barely any wear. teeth on sleeve are in great condition for a k series with minimal wear. please look closely at all pics.
