You have the ability to take your trans apart and put it back together, but you are unable to take the clusters apart as you may not have the correct tools and equipment. The thought of some parts which are sensitive to the install, and are directional, during assembly might be a little scary. One little mistake and all of those expensive parts are toast! No need to worry! If you are willing to ship us your gear clusters we will be willing to do anything you'd like to them!
You can trust Jacks Transmissions to do it correctly with the best parts in the business to give you a long and trouble free service life out of your trans. We also have the equipment to double synchro gears, and modify parts to fit EVOIII assemblies, newer style synchros, etc. All you will have to do is just pop them in your trans and go!
We also spend a lot of time on synchro timing, alignment and operation to give you the best shift possible. Click -> Synchro Blueprinting
It is difficult to come up with rebuilds for clusters as everyone wants something different. If what we offer here is not what you are looking for, please email us at firstname.lastname@example.org and we will find the best option to fit your needs!
