We have recently had feedback from one of our customers who put 70,000 miles on one set of our orings. Getting that many miles is dependant on driving habits. Given our new HBNR O-Rings that number could have been in the 85,000 mile range. No matter what your driving habits, you can replace orings as a consumable indefinitely and we always supply oring replacements with the kit or free if you contact us with your original order information.
Happy Shifting! ---- Andy
My name is Andy and we have been selling this fix since February 2010. Lots of success with it I may add. It is working for almost 100% of the people who tried it. Feel free to comment on the blog and I will try to update it when I think there is something good to share.Please take our survey if you have used our product as the detail in it will help us serve our customers better.
