Adding to what everyone else has said, i doubt your 6" lift and 35's are helping the issue.

 

Huh, ?

**EDIT**
Sorry, little slow, I get what your saying, lol.

 

Yeah, that definitely doesnt help, but is definitely not causing 5 ps pumps in a year, there is something else wrong, and my guess is that its in the way the pump is being joined. flushing all your fluids should be helpful as well.
