Pro Comp U-bolt kits are pakaged complete with new hi-nuts and extra thick washers. U-bolt lengths are usually adequate for stock and aftermarket leaf spring packs. Pro Comp U-Bolt kits are manufactured from low-alloy high strength steel. Round style U-bolts are zinc plated. Square U-bolts are unplated in order to preserve the integrity of the steel at it's bent points. U-bolts are equivalent in strength to a Grade 5 bolt.
Right size and worked great. Hopefully they last as long as the oe but we'll see.
They came just as advertised and work flawlessly. They do not appear to have a coating on the u-bolt itself but the nuts and washers are of high quality.
I used these u-bolts for my 2003 f350 7.3 lariat in combination with the pro comp 6.5” front leaf springs. Went smoothly with no hiccups as the parts fit as designed.
Extra tall nuts so there’s more thread contact These are long enough if you want to add 2 inch block spacers. But I cut off the excess
When they put them on make sure they are straight up and down ,my passenger side wasn’t?
