Anyone know if a 6 inch superlift suspension lift on an 87-91 bronco would require an extended drive shaft? I am assuming the brake lines will need to be replaced, but will I need to buy a longer drive shaft now? A pal of mine suggested that I also modify my steering as the lift will worsen my steering. Anyone know of such a kit and if it is really necessary on a bronco. thanks in advance
I have a 6" Superlift on my 90 BRONCO. Don't need new driveshafts, steering system is not necessary, and you do need brake lines. I got extended radius arms and the Superunner steering kit. I didn't have the chance to drive my BRONCO without the steering kit, but my BRONCO handles much better than my bro's F-150 (6" Tuff Country). This could be because I'm running SSR's and he's running much more aggressive boggers. If anything, I think the steering kit added strenght the weak front drop down brackets. Here's a pic of my front driveshaft clearance. Trust me it's really close. I don't know if the transmission crossmember for a M-5OD is located in a different location from other transmissions, but there is like less than half an inch of clearance. I've done some pretty hardcore wheeling (full compression and extension) and haven't had any problems though. I do hear it bang the crossmember when I hit pot holes though. Not much clearance between that nut and the drive shaft.

Oh yeah, the xmember has to be mounted differently for different trannies. In this instance I think the E4OD would be superior because it's the longest of any Bronco tranny, putting the xmember the furthest back. Downside is shorter rear d/s and thus steeper rear d/s angle.
