99-2007 F250/F350 rear u-bolt length measurement.
I know the blocks are different between F250 and F350 so please specify if you can help.
Truck is in pieces at a friends house. We discovered broken rear leafs while removing lift blocks installed by the PO. I bought F350 replacement springs and blocks from a wrecked low mileage 2004. Should of grabbed a u-bolt that was laying under it.

I'm figuring around 13". Just trying to verify so I can order them.
Thank you in advance for any help.

 

Just measured mine. Look to be 14 1/2 of u-bolt length, not counting nut engagement and extra above the nut. Photo of the u-bolt lower section attached.

Thank-you!

I assume you have the skinny overload spring on top and the small spacer it sits on top of. My replacement F350 springs are missing one overload. I will not be using the top overload. The Po must have removed the upper and lower leaf from the broken springs I removed, or they were aftermarket lifted springs. I have airbags that sit on top of the springs.

Exactly the reason my Jeep started out stock. I didn't have to deal with PO mysteries.
