1986 Bronco II.
Can anyone who has installed this kit give us an idea of how it went, were there problems, are you happy with the ride?
Also, we plan on swapping the 7.5 rear end for the explorer 8.8 and as far as I can tell, once we move the spring perches to the top, all we'd need is different U bolts than what the kit has so they clear the larger axle tube diameter. If you think there would be more to do to fit this kit with that rear end, we'd love to hear from you.

I spoke to Duff, but the tech guy is out this week so no definitive answer from them yet.

It is important to get the drive line to axle angle correct and if you think you may go up, put the lift on 1st to ensure the pinion angle is on the money ..)

Thanks. Been reading about pinion angle here. But nothing I read said if the car is supposed to be on it's suspension or if it matters.

Once your suspension is installed, you will have the correct pinion angle to incorporate in your new "flipped" Explorer spring perches.

I bought a magnetic angle level gauge from Sears, placed on my drive line, then had the perches welded on with the pinion @ that angle.
