DISCONTINUED BY VOLKSWAGEN AND NO LONGER AVAILABLE
The .681 5th gear is an excellent upgrade to any TDI. Recommended for those who drive consistently around 70 MPH, the .681 will drop RPMs by approximately 400, depending on wheel and tire sizes. For those who drive faster than 75 and on level surfaces the .658 is probably a better choice.
If your car has over 100,000 miles it's recommended that you change your gear oil as well as your transmission seal with the 5th gear. A 5th gear mod will significantly drop the dB level in the car, making travel a much more pleasant experience for all involved. This works with all manual transmission VWs from 1996 to the present, as well as many older models. Set includes 02D311158 large gear and 02D311361 small gear.
Pulling the gears is VERY easy! Don't sweat the puller instead you are supposed to heat the gear using an electric heat gun to 100C, the gear(s) slide right off!
If you try to pull the gear without heating it you will crack it nearly every time.
Same thing goes for reinstalling, heat it to 100C and it will slide right onto the shaft.
*NOTE: May or may not work on VW MKIV PD cars (2004-2005 TDI) **Update: KERMA tuning now restores Cruise control funtionality in Mk4 PD cars!!!
