Leaf spring center pin

[kaw550]

My center pins are shot.
I found that Napa carries them. Can anyone confirm the size? I have 3/8's on there now but I want to make sure thats right,

It seems like the hole in the leaf spring is a little bigger.

Yes stock is 3/8". The holes have a little clearance.

While you're in there changing them out, it wouldn't hurt to verify that your spring perches are flat. Sometimes they take a beating over the years and no longer fully support the springs 100%.
Not that it's critical that they be perfect, but I've seen some that were pretty rounded off on the ends and tweaked in strange ways.

I upgraded to a larger u-bolt the last time I had them off too. The typical 1/2" diameter ones that come from the aftermarket are much better than the stock little wimpy things, but I bumped it up one more size to 9/16" for some added insurance.
If you're just doing some mild use with the Bronco, not a big deal. But if you're going to wheel hard and run big tires down the road and put more power to it, upgrade-as-you-go is a good policy.

wouldn't hurt anything to drill out and put 7/16" center pins in either. i like WH's extreme U bolt kit too, plates are much better than stockers.

I use garde 8 3/8'' bolts with the heads rounded off. Might not be the optimum choice but it worked for me when I snapped one off with the impact gun late at night. Been there for a while and I can't tell a difference.

X2 I bought them when I ordered my new springs. They are BEEFY.
