We released our original B/D Shifter back in 2012. Since then we have released three different versions. We have also made some small changes to update the design over the years. Now, in 2019 we have overhauled the three designs.
Starting at the bottom we have replaced the white plastic cage that holds the ball with a Delrin bushing. Delrin is used as it is one of the strongest plastics available, it is resistant to chemicals which is great for automotive applications. Delrin also has high abrasive resistance and low coefficient of friction which basically means it will shift smoothly when you first get it and for a long time. This will give you a tighter feel than the original accordion style plastic housing used on OEM shifters. The Delrin bushing is covered with a TPV bushing to keep it clean and anything from inside the bearing. We have replaced the stamped steel base plate with a 0.35" aluminium plate which will be sturdier and not rust over time. This aluminium plate will also add to the rigidity and feel of the shifter. Since this is what holds the bearing assembly we have found the stock plate to have play, be rotted, or not even there if using new aftermarket linkage. We have also added one more threaded hole to increase the rigidity further and triangulate the assembly. Now, this all wrapped around the redesigned lower shaft. We have maintained the adjustable throw from our original shifter but made it adjustable from inside the car. The 6061 aluminium black anodized lower adjustment shaft is machined with notched section to make it easy to spin up or down to adjust the throw. We have machined a sight hole to make adjustment clear and easily measured using the numbered steel internal shaft.
The rest of the shifter will look familiar to our older designs we are sure you are familiar with. We have anodized the elbows black and then machined logo and some edges for a clean and uniform look. All shifters are independently height and throw adjustable.
