This is our CNC machined end solid stainless 304 shift linkage. These can be made in any length, but we keep standard e36/e46 (zf320/zf420) selectors on hand. If you have a custom length requirement, bend requirement or anything else please drop us line we will do what we can to assist. Processing time on a custom shift linkage is 48 hours. The factory single shear selector rod permits a significant amount of play in the connection between the shifter, and the selector shaft on the transmission. We pair high tolerance CNC ends with extremely high tolerance hardware to make the most precise shift possible. The total tolerance of the hardware we are working with is 0.00045" radially. You will not find a tighter tolerance shift linkage on the market, meaning you will not find a better shifting linkage on the market. The average weight of our stainless assembly is 12oz.
