We have recently worked to develop a billet outer blocking ring for the GTO and 3000GT AWD transmissions. This item is a major improvement over stock blocking ring and also allows you tostop 1st abd 2nd gear grinding.
Billet Steel, over 100% stronger than the stock material. The stock material will strip off the teeth with enough with the crunching of the lower gears.
The new redesigned blocking ring now has 7 teeth per segment versus 6 on the old Ring for more strength and better gera change selection
The bloacking ring has sharper teeth than stock had for smoother gear changes too.
We have been supplying this blocking ring to customers along with our Synchrotech carbon synchros to test them ( Now available from this section on the website) and we to say its the best gear changing combination we have ever tried, just goes in gear like butter!.
