Looking for a better loc than their's. I have had 4 failures with them in the past 2 years. Most were caught before any major damage,,ONE wasn't.!!..guess whose engine that ONE was on??
It appears that some of the locs are soft, as in not getting the heat treat that the others are getting. It is not a complete set that is wearing and pulling through, just one on an entire engine.

If you like drag racing, support your local track.
