Dieselgeek Sigma 6 Speed Short Shift Kit
Sigma 6 Speed Short Shifter for VW Mk4, Mk5, Mk6, Mk7 and Audi 8J, 8P vehicles equipped with a manual transmission
After several months of tinkering, Dieselgeek has come up with some revolutionary changes to the Sigma 6 Shifter. The goal was to keep all of the goodness that is Sigma but reduce the time it takes to install the shifter and get the adjustment right the first time. The first new feature on the list for 2021 is the Nutbar for the front to back cable end. This laser cut stainless bar is threaded for all four clamping screws on the billet aluminum Sigma cable end. This allows you to use one hand when tightening down the four Allen screws. Before there were individual nuts which required you to hold them with a wrench from underneath. The Nutbar is a big change and will save at least ten minutes of install time.
The second and even larger change is the switch to precision machined Delrin inserts for your stock side to side cable end which is used for gate selection. By switching back to a hopped up stock cable end, the super slick adjustment function is retained and makes the adjustment, (or readjustment) a breeze! The Perfect Pivot Delrin inserts do not have any extra play in them which means that they only rotate on the precision pins. They do not flex side to side like stock cable ends and will transfer motion without any losses. The time savings from an install standpoint is a 30 minute reduction at least and the process is much easier. In addition, if you get the first adjustment wrong, readjustment is only a one minute affair. The new 2021 Sigma shifter's ease of adjustment is incredible and should not be underestimated! Because they're under very little load, the Delrin Perfect Pivot bushings should also last forever. There is no performance loss whatsoever over the previous Sigma cable end: It's all gain.
The Dieselgeek Sigma 6 short shifter greatly reduces the throw of your shifts by replacing the entire under hood shifter assembly with a full billet unit. Installing this shifter will result in crisper, more direct and shorter shifts; perfect for those that like to slam their car into gear under heavy acceleration.

Please read this, especially if you have a Mk4.
If you are having any issues shifting, Dieselgeek suggests replacing any bad shifter bushings prior to installing the Sigma shifter. The Mk4's are only getting older and it is likely that one or more bushings in your shifter box needs to be replaced. If you have bad bushings in your shifter box, you will not be able to properly adjust the shifter. Watch this YouTube video and do the test shown prior to installing your shifter:

Please note that this shifter can be on the notchier side when compared to the factory shifter and requires a slightly heavier throw to fully engage. This shifter pairs well with a BFI heavy weight shift knob since the extra weight helps to "push" the selector into place. If you prefer a shift that is shorter but feels smooth like it does stock, we recommend using the APR shifter instead.
