I have an 04 silverado extended cab with a 6 inch pro comp lift and currently am running 315 75 16 tires. I don't 4 wheel the truck any but yet I have replaced the pro comp mx6 shocks with billsteins after the front drivers side busted. Now the billstein on the same side has failed as well. The truck has never been wrecked and is driven on paved roads mainly. Can anyone give me any ideas on what to look for to solve this shock problem? Thanks a lot.

Was the truck aligned properly after your lift was installed? And Welcome to the forum also.
