Missing something for my porterbuilt setup??

[83c10wit454]

So I already have the crossmember and trailing arms from nate. I'm wondering what keeps the rear end from spinning, I'm guessing the u bolts don't exactly accomplish that. I also have a panhard bar from qar and will be running bags over axle. I believe I need more than just shocks to complete my setup. Help please! Thanks

The trailing arms will become a fixed mount when attached with the u-bolts... this will keep the axle from rotating under load.

Sounds like shocks are all that's left.

so no perches or anything? just arm directly to axle tube correct?

What year truck are putting these arms on?
Also what style/year rear end is it?

Your axle should have perches... If not, you'll need to weld them on! If it's for the truck in your avatar, you most likely have a leaf spring set up. If your switching to the trailing arms, you will need to mount the correct perches under the axle for the TA's to properly mount. UNLESS... Nate designed it to be used with the factory perches on a leaf spring set up!

There should be a mounting pad welded to the bottom side of the axle tube that the trailing arms bolt up against. If you don't have any, get in touch and I can get you a set!

Since the rear end is a 10 bolt set up for leav springs, you will need to remove the leaf spring mounting pads and install some trailing arm mounting pads. We also have a different lower shock bar for the truck 10 bolt.

Its actually a 12 bolt with leafs. Guessing in might be more mid 70s if that sounds right. And were might i be able to find mounting pads for trailing arms?
