Your question isn't complete, as we don't know what size the truck is you are asking about, and how you intend to drive it. | | | | | Joined: Jan 2008 Posts: 502 Shop Shark | | Shop Shark Joined: Jan 2008 Posts: 502 | Along with what daddy said, diff. ratio and tire size are needed factors that will come into play when choosing a trans.
