Pete 379 Front springs replacement. 20K pounds

Those shims set your caster angle. Make sure they go back in the same place or you could have issues with steering stability.

The blocks, I just call those spacer blocks. Probably used more for ground clearance since you've got a vocational spec truck.

 

Aluminum blocks on Pete's usually have wear, I usually replace them with cast ones. Yes, springs will come with bushings so replace front pins. Don't forget to get shim assortment for side bars.

 

If you call somewhere like stengle brothers in Whitehall they can let you know what you need for that.

I don't know where you are getting your parts but I have bought suspension parts from them before and they were very helpful and reasonable.

In fact one time I ordered airbags for my trailer and somehow they sent me the wrong airbag. It was a Friday when I got it and I wanted to have the trailer together to go back to work for Monday.

I could not make it up there before they closed on Friday but they were nice enough to meet me by the turnpike and make the exchange so that I could get the trailer together and get back to work. And they also deleted the shipping charges.
