rear perch width

[casey]

I'm not familiar with the differences between the MJ and the XJ rear springs and perch placement. In the FSJs the J truck has it's springs farther outboard on the axle than the Cherokee. And a wider rear axle.

 

I just grabbed an XJ parts rig for an FSJ project. It has an 8.25 in the same ratio as my MJ. I was planning to swap the 35 for the 8.25. I took some quick measurements in the rain yesterday (both axles are under rigs), and it looks like the XJ has the perches set farther apart.

By only an inch...is that so?

It's a little more than an inch. If you use metric numbers you could be accurate, but, it's about 42" (MJ) vs 43.5" (XJ).

Yep, that's about what I measured.

 

Thanks. 8)

 

I have some perches and will go ahead and do the rear in SOA.
