Does anyone know why the left rear shock is angled towards the rear and the right rear is mounted angled towards the front of the truck? I noticed that last night and was just wondering the reason behind it.

 

They do this to help reduce axle hop, and to help handling.

 

just like don said it's to help with the way the destribute the wieght int eh truck. ie where they put the gas tank, the battery, where people sit. you have probly noticed that the gas tank runs along the left side only (same as the driver) that's anywhere from 200-550lbs on one side and rear a little that isn't on the left
