Choosing the Right Shifter Setup

We call our newest shifter the ISO Shifter, it is available in two different reduction ratios. The reduction ratio refers to the throw or travel of the stick from gear to gear. The 5% reduction version has a throw that is similar to the stock shifter while the 20% reduction version has a shorter throw that is closer to a typical short shifter. The ISO Shifter features a Polyurethane Isolated stick that dampens vibration extremely well. With the ISO Shifter you can have a smooth, precise shifter that is easy to move through the gears and keeps vibration out of your hand; a combination you can not get with any other shifter in a Corvette.

Below are your two options for choosing an ISO Shifter Kit with an Upgraded Factory Box. If you would prefer an ISO Shifter Kit with Billet Box you can select this option from the collection above or from our Parts Page. All of our shifter kits include stainless hardware and everything you need to replace a sloppy factory setup.
