One of the great features of our “toploader ” sequential shifter is that its easily adapted all other 4 speed transmissions with external linkages on the left side by changing only shift rod lengths and the shift arms on the box. We now in the process of prototyping the arms to suit the gforce tex racing 101 box.
In the world of social media this discussion often comes up with internet experts trying to tell us our shifters are not a true sequential. Well the hard fact is that our shifters are as sequential as they can possibly be, the definition of sequential is for it to be in order. A sequential gearbox is not necessarily a dog box and a dog box is not necessarily sequential, the internal engagement method is unrelated to the shift pattern. Our sequential shifters work great with dog or synchro gears.
To see a great explanation how synchros work read this article from Tremec, https://tremec-blog.com/manual-transmission-synchronizers-101/#:~:text=To%20engage%20a%20gear%2C%20the,mesh%20with%20the%20next%20gear.
Dog engagement can be seen clearly here http://www.mechanicalwalkins.com/wp-content/uploads/2019/10/Dog-CLutch.jpg
Of the two methods synchro engagement is by far the most refined and greatest technical achievement but the dog engagement definitely has is place in some race cars.
This shifter will suit all the early 4 speed manuals with external shift rods on the left side of the box , Andrews T101, Gforce 101, Jerico, Muncie, t10 and we do expect there will be high demand for these as many of you still use these in race cars with dog gearsets . The design has a unique lever virtual pivot system that allows us to have a high lever with a very short throw and move the lever to almost the center line of the box.
