I usually freshen the engine up each winter anyway...but the most runs ive made on the back cut low tension rings was 350 in one season...that was running combos/national events/div races/test n tunes/ and bracket racing....never really slowed down, most of the time it was faster at the end of the year then the begining from testing. ?

I have been buying my low tension ring from Tri City Performance in Vista Calif. for past decade. Although the design has changed, they have lasted at least as long as the Speed Pro Production rings I used to use. Greg has even put them in a street car before! My current set in my 340 has over 600 runs in the last 4 years..still leaks down great !! John Irving 741Stk/SS
