I am thinking of rebuilding my g/box when the engine is finished. Has anyone run them and have any good/bad experiences from their use?

 

would like to know as well. in the process of rebuidling mine

 

didnt notice any difference when installing mine, if you have grinding problems or anything else of that nature, putting in new synchros most likley wont help much. Sliders suffer from the same wear as well and should be replaced accordingly

 

If you're road-racing, are a perfect shifter, and eat gearboxes like crazy, it would be a good idea. If you get bad synchros from shifting too fast or not being a perfect shifting, they won't help much. A sequential g/box might, though In other words, hardened gears/synchros will still wear away if abused or used improperly.

 

I purchased their race tranny for my race car and have been very happy. I run a sohc, which people don't make very many good parts for, putting out over 500 whp and I have not had any problems shifting thru gears. Their race trannies come with stock gears, carbon coated syncros, and a qauife lsd. I use them on customers cars as well. Good investment for the price.
