I am in the process of removing the cab to my truck"for powder coating!" as well as the engine"Rebuid", trans"Rebuid", t-case"Rebuid" etc... All that is left is the frame. Now is the perfect time for a SAS!. I know the spring hangers are set by location but the shock tower is not. With no weight on the truck, how does one properly place the shock tower? Or is the slight spring compresion due to vehicle weight no important? Let me know what you think!
