Truck is 2006 silverado Ext. cab. with 20x8.5 wheels and 275/55 tires. I am currently running 2" shackles and spring clamps on the rear. The truck sets fairly level. However, I am considering just dropping the front down 1" with a set of drop coils to get just a little rake. Would I run into any problems dropping the front down 1" with this tire size?
