Default How can I increase the wheelbase? (40)

And so the mods begin...

Is there a way to slide the rear axle back like 2-3"? Flip the spring around, or get a different spring, or do I have to get a longer spring then have someone weld on a new hanger further back? Just think it looks goofy with the rear tire tucked so far forward, plus with the longer wheel base it would be more stable.

And after seeing this pic I'm putting the hard top on this winter for sure.

You ought to change the title to "Nakman's 40 Build Thread"

You need an SM420, too.

The axle is going to move rearwards under compression so don't move it too far back. Flipping the springs would require body mods. You can redrill the lower spring closer to center and I think it would be fine. Keep in mind the pinion angles will change and any addition in length will require drive line modifications and brake lines may need lengthened.

Reverse the rears or 55 rears or link it. Treeroot is right though, you will need to mod the bod.

I reversed front and rears using the existing mount points and my wheelbase is 98 1/4".

Flip the rear springs and take a sawzall to the fender wells. You must retain the leaf with the military wrap in it's original orientation and redrill it for the new center pin location. Don't forget that will cost you retubing your driveshafts, I paid $236 at Englewood Driveshaft when I got mine done for my 4 speed conversion a few weeks ago. You can also use pig springs, as has been mentioned. Since they're longer you'll need to cut off, flip around, and reweld the rear shackle perches. As above, you'll still need to get your drivelines changed.

The thing about pig springs is that you've currently got a 4" lift IIRC, so you'll have to figure out how to lift the rear to the same as the front.

Ok that makes sense, thanks Jeff. I'll probably take a "wait & see" approach to the sawzall though.

If you flip the bezel, everything else will look better

You will need it, with 33's I had to cut the wheel wells and that was before I reversed the springs.

Don't forget, if you reverse the rears you will need a new driveshaft and your pinion angle will be wrong. You can either cut off and reweld the perches or shim it, shims would most likely suffice.

I run 33x10.5 with 2-3" lift and the rears stuff nicely inside the rear fender wells without needing to cut. 33x12.5 would need some trimming though. He's currently got 33x9.5 with 4" lift so he's fine right now, but moving the rear back would definitely require cutting some off the back for the wheel opening.
