Hotchkis leaf springs sagg brand-new

If you look at DTMRacings post, depicting their current project it shows that there is 4" of clearance in the driveshaft tunnel WITH 2" blocks under the axle (so 6" clearance); my perches aren't big, I think they are comparable to stock (you can see them in some of my pics). I doubt I have much over 2.5" clearance sitting as I am.

I went so far as to think maybe the dana 60's Hypoid offset is significantly more than ford 9 inch or Chrysler 8.75, below is the article- its negligible in my opinion.

Add less than 1/2" for the Hypoid offset bringing the yoke closer, 1" for thick perches, 1/2" for a 1350 vs 1310 yoke, ill even assume my pinion angle is severely off @ 1-1/2" higher and I should still have ~4" of clearance similar to the pics DTMR provided. Sorry, im not convinced its the Danas fault.

Whatever caused this doesn't really matter to me anymore, my truck is done and im moving forward with my plans of pulling the Demon from the road; with any luck those Hotchkis springs will be in the garbage by new years. But I have learned lessons from this experience, so at least theres that. Ill put my GoPro under the car within a week or so just for some fun and do a couple hard pulls.
