Rear Leaf Springs - Ranger vs. Comanche

[socomanche]

I'm wondering if someone smarter than me can explain why I shouldn't use 1750 lb Ranger leaf springs instead of 1700 comanche leaf springs to replace my current leaf springs. Here are the links and specs for each. The reason I ask is the Ranger springs are $130 and the Comanche springs are $250. The A/B measurements, the leaf pack breakout and the pack thickness are slightly different, but I don't see how these would affect anything drastically. The only thing I'm not sure on is the difference in arc between the two. Any advice or opinions are appreciated. Thanks!

The arch is dramatically different the Ranger is spring over axle whereas the Comanche is spring under axle

 

Just probably 3 and 1/2 to 5 inch difference in Arch

Thanks! That solves that question. Does anyone know of a rear leaf spring from another vehicle that has a similar arch and length / width dimensions that can be used in place of a Comanche specific leaf spring?

Does this just mean less lift? So this would be an option for anyone looking to lower their MJs?

I will commend socomanche for bothering to look around, at least. 

 

Yes, to answer your question. 

I recently recommended Nissan Frontier springs to one of the low-riders here who did the drop-block routine. 

 

Another option would be to go SOA with a flat spring, you may end up with 3.5-4" of lift instead of 6-8'' of lift. What's the benefit? IDK, but at least you can center the wheel in the tub without worrying about the tire/wheel travel fore to aft.........that's such a line of BS anyway...........(Hell Creek's crap IIRC or Rusty's or....)

 

Jeep people have been so conditioned to the "kit" mindset that.........well.........I just shrug anymore.
