My friend broke one trying to take it out of his 6L. First the extension broke and then when he got a new extension the bolt broke off. He's not a very big guy either. Made a thread on here and found a couple other guys who did the same.

Had to pull the engine and swap the crank.

Luckily for me i havent had an issue with my arp crank bolt although its tough to get out sometimes.

 

Wow. I would have never thought...

 

i'll stick with $3 the stockers, thanks!
