This is irrational; but the heart wants what the heart wants. In case anyone was curious, here's how I happened to do it:

On the front:
-Bronco control arms (wider than Ranger for slightly more wheel travel and tire clearance)
-F150 tie rods (2010s vintage, if I recall correctly)
-Reamed the knuckles to accept the bigger UCA and tie rod ball joint tapers
-Widen upper control arm mount at the frame to accept bronco UCA (LCA just bolts up)
-Axle half shafts are Bronco parts with Ranger inner cups
-Cut 2" out of the fenders (my engine bay misses my fender liners)
-Modified, revalved, and shortened King pr2508od-cohr-a dampers with parts from Filthy Motorsports and custom machined coilover adapter to suit the "Branger" setup
-Running max caster at the LCA to move the tire forward in the wheel well
-When you think you've cut enough, cut more and cycle the suspension without springs to check clearance at bump and steering lock

Rear:
-1" spacers (would have gone just a bit wider in hindsight)
-Spring under axle setup with modified Rubicon Express Jeep XJ 6" lift leaf pack
-Laser cut 12" shackles
-Short body Bilstein 7100s 10" stroke, 360/80 valving modified for less bleed
-Cut fenders
-Raptor bump stops (stock shown)

Other:
-17x8.5 +25mm offset Method 313's (positive offset helps a bit with scrub radius and clearance at full steer lock)
-Ford Performance tune and 91+ octane always
-Cooper AT3 XLT 37x12.5r17 (note some photos show my old 285/75r17s)

Still to do:
-4.46 gears are ready to go in
-Rear needs more clearance to bed at full articulation. Thinking about a welding up a "trail" flatbed...

Dreams:
-Bronco m210 front diff or Dana Ultimate FDU
-Link the rear or just run longer leafs and bigger dampers with a bedcage
-wider rear axle (or just run negative offset rear wheels and forget about tire rotations, lol)
-4.88 gears
-raw finish bead locks or method bead grips

This was the rough plan since I bought this truck 3.5 years ago. I've been slowly doing all this stuff with 37s in mind and I still have lots more to do to make it really "work" the way I want it to.

As an aside, I run the transmission only in 'S' mode. With the 37s, a "built" 10r80 or at least some transmission tuning might called for soon; I'll see how the 4.46 gears feel.

That is an amazing job. Love it!

Please keep us updated on how the install goes. I’ve heard they fit and I’ve heard they don’t fit. I don’t know what to believe anymore…
