This will be a very slow process of me buying parts and then installing them at one time for the most part. What I have is an 07 JK Rubicon with just a 3" lift and ugly bumpers. It just hit 240k a few days ago and that means it's plenty broken in. I will continue to drive it daily until things are ready to be swapped in. There's a purpose to this build but it'll be obvious eventually, as long as I don't change my mind. So axles were the first thing I had set out to find. Most people like the 05+ super duty axles because they are just plain ol' beef. I stole this info but here it is. 05+ Ford Super Duty D60 Axle Specs: -Tubes: 3.75" OD, 1/2" wall -WMS to WMS: 72" -Ring Gear: 9.75" (a 10" can be sourced from Ford in limited ratios) -Lug Pattern: 8x170 -Wheel Studs: M14x1.50 -Axle shafts: 35 spline -U-joints: 1480 -Tone ring: 60 tooth I couldn't find one for a reasonable price with 4.10s (what I have now) so I found a '90 kingpin Ford Dana 60 with 4.10s. What I know about the KP D60 axle I sourced. Tubes: dia. 3.125", wall thickness 0.5" Ring gear: 9 3/4 Axle shafts: 35 inner/30 outer* Lug pattern: 8x6.5 UJoint: 1480 WMS-WMS: 69.25" I hear about the knuckles being weak on the Ford versions but they can be gusseted or replaced. *You can swap the 30 spline outer for a 35 spline flavor stub shaft. I'll have to replace or modify the DRW hubs. As far as the rear axle goes I'll probably snatch up whatever I find cheapest which will either be a 14 bolt or sterling 10.25/10.50.
