If you used a traction bar in the back, would it take away form your flex in the rear end? How can you use a trcation bar and stilll get MAX flex?

 

If you used Heim joints I think you can achieve this

That's exactly the type you need - it will prevent all axle wrap and allow full articulation. Mine is homemade, but basically the same. Bud's is great in that it requires no welding.

 

Anti-wrap leaves are another option. They work well and have no impact on flex. Many of the better aftermarket rear springs come w/ a/w leaves already installed, such as the Alcans I used to run:



Basically, it is a halflength leaf on top of the spring pack with a clamp running underneath the pack. It works by pulling up on the clamp in response to the axle trying to twist upward.

They worked so well, I added some to my home-made front springs:

You can see the a/w leaf on the top of the rest of the leaves:

 

here's one I built for an SAS taco with a D60 rear end, the shackle and hiem are the key to flex

 

Do they have fitment for 7.5" rear? The reason I ask is because my 84 2wd pickup has a 7.5" rearend but on Bud's site, they only list 8".
