Quite the shock angle you have going there. Effective ratio has to be about nothing. Not trying to be a jerk, just commenting.
Regarding the crossmember, did you guys cut every single rivet or keep it together? Also not sure how I’m going to get to the upper inside rivets to cut them and then getting a drill in there to redrill the top ones. Unfortunately my exhaust is welded front to back and this would be easier without that in the way. Maybe this is the time that I remedy that issue.
They're stupid stiff Superlift dampers for a Furd with an 8" lift I got off eBay from Superlift when they used to clearance things out on eBay... for $9.99. I still have a bunch more of them new in box, they're still so stiff you can't move them by hand. They were temporary to try to stop the Interco bounce when going down the highway at 55mph. Worked well enough that I never bothered to do anything about it.
The long story is that it was supposed to be a build that was cheaper than the tires I put on it and weigh under 2500lbs with me in it for snow wheeling... and zero tube to make fun of all the Jeep people that spent all their time bending tube and putting Chevy parts on their Jeep. I think I paid $1700 for the 44" TSLs new to my door a dozen years ago and when I bought brand new Tuff County 56" springs it barely pushed me over the $1700 for the rest of the vehicle. It is exactly 15' long and has exactly 10' of leaf spring.
It has been sitting with a tarp over it since 2007, this picture is from 2010, the last time I trailered it somewhere.
This is the frame with most stuff removed, the only thing that stayed in the original spot was what you see EXCEPT the engine crossmember had already been moved:
This is how I drove it for a while, with 40s, kept getting hung up on the factory crossmember even though I clocked the transfer case flat so I later built a new one so I could have a flat skid plate. At this point I had paid for the tires and wheels ($700+300, used), the rear springs ($100, used), 4 new Superlift shocks ($40+ shipping), a pair of steering knuckles plus machining ($125), a steering arm ($50), a clocking ring ($50 but it was a trade), new brake lines ($80ish), and a couple of Superduty shock towers ($19 each I think). Everything else I already had. I did end up buying new lift springs for the front after destroying 4 sets of factory 56" springs and I destroyed one hydraulic bellhousing.
In 2007, since I hadn't managed to break a shaft yet (the only thing broken to date is a bellhousing) and I hadn't put the D60s under it yet, I bought 44s for it. At this point it has a TBI 350 out of a G20 van because the TBI 305 I had forgotten I hadn't drained the block (straight water) when it froze one night in September. It could actually move pretty good with a TBI 350, was fun to burn donuts on US41.
Shortly thereafter, I got a new job in Wisconsin and it has been sitting ever since. Things were different 15 years ago.
