Haven't posted in here in almost 3 years! I'm back! Anyways, I'm looking to relocate across the country and may be using my 08 silverado to help move some items. I was thinking of getting some helper springs to help with a heavy load. Can anyone point me in the direction of a good brand? I saw some generic ones at Autozone for about $50.. would increase load capacity by 1000 pounds.. help?
