Ok, I have been trying to scour the web looking for my answers, but I got nothing. I'm trying to find the difference between using 5 lug and 6 lug in 1/2 ton trucks. Ok, here's what I kinda know: Most GM 1/2 tons that are 4x4 use 6 lug and now most current 2wd use it as well. Traverse also had 6 lug. All GM 3/4 and 1 ton trucks use 8 lugs. The same pattern follows with GM vans. Ford 1/2 tons use 5 lug even the Expedition which weighs as much as a Suburban. Some F-250's have 6 lug but most have 8 and all F-350s and Excursions have 8. For who knows what reason the E-series vans have 7 lugs and 8 lug on the heavy duty ones. Dodge does the same as Ford except all 2500s and 3500 have 8 lug.(I think) The Durango (closest thing to a full size they have) is 5 lug. The Sprinter only was a 6 lug even in the 3500. Toyota Tundra is 5 lug like the Ford and Dodge. Sequoia is also 5 lug and meant to compete with the Tahoe and Burban. Nissan Titan, Frontier, Armada, and old Xterra are all 6 lug and the new NV van is 8 lug like larger GM vans. So, question is what is the difference between 5 lug, 6 lug and etc. Does it improve towing capacity or axle strength? Is it about power? I really want to know.
