The Stovebolt Site Forums The Parking Lot Big Bolts Disc brakes for 1.5, and 2 ton trucks

You can do the exact same spindle and brake swap with the 3500HD front axle as you could with the P30, those parts are the very same.

The difference is the steering linkage and the arms or bell cranks bolted to the spindles.
The P30 tie rod and drag link are in the same places as they are on your old 2 ton, this makes for very little adapting (can usually use original tie rod, reaming arms to fit if necessary). Also makes steering and drag link simple to adapt to the original box.
The 3500HD has all the steering linkage in front of the axle, a "Y" type it might be called where the drag link is anchored to the tie rod. This setup may or may not easily fit above springs and under oil pan. The major problem is you'd need a different steering box to make it work. I have used this setup on my truck but at the time I had no idea the P30 version even existed, that is what I should have used.
