I am looking at doing a custom shackle reversal on my 73 FJ40. Now from what I read some people put the short part of spring in the front and others put the longer part of the spring in the front and extend the frame alittle. Which is the right way or better way?

BTW this is a daily driver.

Thanks
Rob.

Long part forward is correct. People switch it to get longer wheelbase. You need to be aware of pinon angle when you do this, longer driveshaft, probably some sterring modifications. It is probably more commonly done in the rear.

The long part of the spring should stay with the shackle,... that's the part of the spring you want to flex the most. So if you do a shackle reversal, the long part of the spring should face rearwards. The frame extentions you read about are probably someone putting FJ 55 springs in (they're longer, thus they decided they wanted to extend the frame).

Hope this helps

IIRC, you should reverse the 2nd leaf, the one that attaches to the shackles. The rest of the leaves stay the way they were. When you reverse the 2nd leaf, you will have to re-drill the spring pin hole so it will be centered with the others.
