My qa1 1.25" heims have lasted me a long long time. They came from midnight 4x4 in like 06. I also have some ruffstuff on the rear and they seem to be doing their job. If you want the best and strongest heim in the world, look at EMF heims out of Canada. I am slowly switching all my joints over to them.
Besides being the strongest, They dont squeek when they are dirty!!!! Worth the price of admission right there
