To permanently fix this, a change in the fundamental design of the pivot is required, changing the assembly to a double shear system with the UUC Double Shear Selector Rod (DSSR).
Unfortunately, this is only a temporary fix as the new joint's bushing will exhibit the same rapid deformation. (figure 3)Ī temporary fix is to simply replace the selector joint. The result is an in-gear shifter "free play" of 3/4" and up to 1" in either direction, over 35mm total. The looseness and slop are magnified by the leverage-multiplication effect of the shift lever itself. 2 image shows a selector joint that has approximately 25K miles of use. The result is a steady deformation of the bushing, resulting in looseness and slop in the entire mechanism. The design of the selector rod has a pin at 90° to the main rod, which exerts a tremendous amount of leveraged force on the selector joint bushing from one side (known as a single shear force). We already know how badly plastic wears in an automotive application, and these areas are not an exception. In the original BMW design, the connection at both ends has a large injection-molded plastic bushing. One significant wear area that has never been addressed previously is the wear and ovalization of the linkage connection points at the transmission and the shifter's lower pivot. While producing a "short" shifter, our more important goal in improving the BMW shifter assembly is to increase the precision and smoothness of the overall operation. ** Add one to your UUC Evo 3 kit by clicking above** The goal: UUC's optional 'Double Shear Selector Rod' These do not wear or ovalize like solid-metal or plastic designs with expanding tolerances. * zero-tolerance lower pivot bearings that never require lubrication and eliminate significant mechanism friction. * linkage geometry perfectly corrected, with self-adjusting primary pivot bearing that permanently retains lubrication and precision (some models). * flex and rotation-free lever construction with full-length vibration-absorbing bushing. * height adjustment via upper-section length change (this does not change linkage geometry like moving-ball designs). The unique characteristics of the design include: With that in mind, our latest generation brings the BMW shifter to a new level of smoothness and minimized shift effort. In the interest of continually improving our product, we are always developing and testing modifications intended to bring "ultimate" to higher levels. Our products are not modified BMW components, and they are not "one size fits all" as with lesser offerings. Our design starts with the finest materials: T-304 stainless steel, T-6061 aircraft-grade aluminum, precision bearings, self-adjusting and lubricating primary pivot bearing, and the finest-grade silicone vibration absorbing material. The UUC Ultimate Short Shifter is unique, completely different than anything else available. **When ordering, please make sure you carefully select your shifter choice,Įspecially if your car has a transmission swap** I don't think there can be a more resounding endorsement than that. Our feeling? The UUC Evo 3 Shifty kit is the best and by-far worth every cent! We have sold, installed and used just about every short shifter on the market Smooth and tight, the Evo 3 line of SSKs are a favorite of enthusiast around the There is a reason UUC's Ultimate Short Shift Kits are some of the most popular upgrades for street driven BMWs.
