Shortly after the release of our Billet RSX Shifter we started to receive several inquiries about making a similar shifter for the B and D series engines. At first we were a little hesitant but after some thought we remembered that we actually made a prototype several years ago. So we got it out made a few changes and produced a couple more prototypes for testing and feedback purposes. Testing went very well and the response to our photos was also excellent so we decided it was time to make this product available.
he K-Tuned B & D Series Shifter was designed with full adjustability in mind. The shifter pivot ball is height adjustable shifter height is adjustable and the offset elbow of the shifter can be rotated to several different positions. The adjustable pivot ball allows the user to thread the pivot ball higher up on the shift rod to shorten shift throw if desired. Construction is as expected only high quality materials are used to ensure the shifter will last. We used 100% stainless steel with the lone exception being the offset elbow which is made from billet aluminum. All hardware spacers and allen keys for adjustment are included in our kit. This is a great shifting upgrade for any B or D series engine setup.
Pro Circuit Shifter
Since 2012, when our original B/D Shifter was introduced we received several requests to make our shifter taller. It seems a few of our customers were using our shifters fully extended for circuit racing and in some cases they were even adding an extra 4" shift extender to increase the overall height even more. Although this might seem fine, the added height increases shift leverage and our original design was not made to support this modification. The requests for a taller set-up continued so we designed the K-Tuned Pro Circuit B/D Shifter. We also had requests asking us to put the look of our Billet RSX Shifter into an option for the B/D users, so we started making a few changes.
The most noticeable change to our new design is the offset elbow, which is now locked in a fixed position to increase strength, it does not rotate any more like our original. The new elbow now allows a maximum height setting that is 5" higher than stock. We now use a brass pivot ball and a more stable bearing set-up to further reduce friction. The pivot ball is threaded and still allows the user to move it up or down to adjust the shift throw as desired. For construction, only high quality materials are used to ensure the shifter will last even in the hands of aggressive drivers. A mix of 100% stainless steel is used on the upper and lower rods, the offset elbow is made from billet aluminium and the new pivot ball as mentioned earlier is now made of brass. Like 90% of our product line, this shifter is 100% North American made as are all the raw materials. All hardware, spacers and Allen keys for adjustment are included in our kit. This is without any doubt, the ultimate shifting upgrade for any B or D series engine set-up.
