Easiest Way to do a 4/6 drop on a project
Let`s say you have a short bed project that you want a 4/6 drop on,you want the f/e rebuilt,new brakes,and a rebuilt steering box.You`re doing a swap from an I6 250/3spd to a 350/M20.You have a 3.40 posi,but the truck has a 4.10 rear.What would be the easiest way to do all this.Remember,I may be ambitious to want to take this on,but in reality,I`m kinda lazy.

Re: Easiest Way to do a 4/6 drop on a project
spindles, springs, and an adjustable panhard bar. I would recommend ECE.

ECE sells a complete front-end rebuild kit for the steering, but it is really pricey. You can go to Napa and get all the parts for a lot less. Out back, I would run 4" springs and 2" blocks. You won't have to c-notch, but you'll bottom out sometimes. Replacing the rear end gears is pretty complicated and unless you have experience doing rear-end swaps I would just take it to a shop. Misaligned gears can toast a rear-end in a matter of seconds. Either way, I would go ahead and do the rear end all at once. If you do the blocks out back you have to take the u-bolts out anyway so it'll be pretty easy to do everything at once. My u-bolts were rusted into the trailing arms pretty good. It took a lot of degreaser and a BFG to break them free. My air hammer helped too....

The super track bar mounts at the frame like the stock one does, but does not mount where the stock one did. It mounts to the opposite trailing arm. The benefit of this is it is a longer bar and allows the rear to stay in its center alignment position longer through the arc of the suspension before it shifts.

But when I bought my kit (5-6 year ago) they just called it an Adjustable Track bar. Thus the reason for my confusion. |

Re: Easiest Way to do a 4/6 drop on a project
I agree with Shane on the chassis parts.
For the front end rebuid, I used the rubber setup from www.p-s-t.com and was happy with that |
