Hey guys, been working on the 73 lately. When I bought it, it had a 4" lift and 33's. Im now changing to 8" (skyjacker) springs with zerorates with 39.5 TSL's. First, a few pics: Before, as purchased basically: And its current condition: Okay... now the question. As you can tell from the pics, Im doing more than just the suspension change, also entire new drivetrain. New front and rear driveshafts. So before I order the driveshafts Id like to figure out my final wheelbase. When I add the zerorates (truck just has the 8" springs installed right now, in the pics) should I extend the wheelbase, or leave it stock? If change it, just front, just rear, or both? Go 1" or 1.5"? Ive researched it and only seem to see people talking about changing their wheelbase just for the sake of wanting a longer base. My main concern is tire clearance. The pics show I have a decent amount now, and adding the zerorates will give me another inch. But I dont want to trim the fenders. I realize with 8" springs this thing isn't gonna have alot of flex, maybe this isn't even a big issue, I don't know. Basically, what do you guys think? Id like to figure out what to set the zerorates at (offest or centered) so I can start thinking about ordering the driveshafts (HAD). Any advice on why I should change the wheelbase or leave it alone would be appreciated. TIA guys.
