Jeep365 Posted January 2, 2017 Share Posted January 2, 2017 Has anyone gone soa with metric ton springs? I've searched around and can't find any info on it? Bought my first comanche a couple of months ago and I am starting to get a list together on what I need for a lift. I have found the Alexia lift posts so I have a pretty good idea of what I need. Just wondering about the metric ton springs in the rear. Link to comment Share on other sites More sharing options...
Pete M Posted January 2, 2017 Share Posted January 2, 2017 No reason why you couldn't. :thumbsup: going SOA lifts it 5-6" over whatever height it is now. I added leafs to firm up my standard packs when I went spring-over. Link to comment Share on other sites More sharing options...
Jeep365 Posted January 2, 2017 Author Share Posted January 2, 2017 Ok. Thanks! I wasn't sure if it would lift the truck any more than the regular non MT springs Link to comment Share on other sites More sharing options...
Pete M Posted January 2, 2017 Share Posted January 2, 2017 nope, you're good. :thumbsup: weight carrying ability doesn't affect the gain from a spring-over conversion. Now, you might be on the high end of what you'll need to hike up the front, but not any more than a set of 4x4 leafs in good shape. From the factory the Metric ton leafs didn't sit any taller than regular packs. They just resisted sag better. :yes: Link to comment Share on other sites More sharing options...

I have thought about going soa, but my metric ton springs are near brand new and I'm worried I would end up with enough lift to put me somewhere in the stratosphere.

mikekaz1 Posted January 3, 2017 Share Posted January 3, 2017 A SUA to SOA swap will net the exact height of the leafs + mount + half the axle tube. This is on all trucks no matter what. Spring capacity or condition does not affect number this at all. Link to comment Share on other sites More sharing options...

Spring capacity or condition does not affect number this at all.I understand that, but the metric ton springs have more leafs in the pack than the standard pack meaning they are thicker and more lift will result, yes? If you stuck a 1" block under the springs while still SUA nothing would change, but if you flip the springs on top, THEN add the 1" block you would gain an additional 1" of lift. I havent measured them, but I'm pretty sure the MT springs are thicker than the standard pack. By how much? I don't know. But whatever the difference is, that is how much more lift would be achieved using MT springs vs standard capacity. Also, why only half the axle tube?

Pete M Posted January 3, 2017 Share Posted January 3, 2017 it's a tiny amount. all our trucks have 1 overload so if he had the double overload variety, it'd mean an extra half inch maybe (thickness of that one leaf). If he has the other variety, it'd be a quarter inch. :thumbsup: Link to comment Share on other sites More sharing options...
gogmorgo Posted January 3, 2017 Share Posted January 3, 2017 And whatever the difference is, it would still be included in the height of the leaf spring pack in the lift height equation. Link to comment Share on other sites More sharing options...

I think your missing my point still. the exact amount of lift is the exact height of the leafs+mount+halftube. so yes there will be slightly more lift in a metric ton spring then a standard spring. but its a precise amount. its nonvariable. so you could figure that out right now in the driveway.

Jeep365 Posted January 3, 2017 Author Share Posted January 3, 2017 Alright so I get that but like ftpiercecracker1 asked why only half the axle tube? My MT springs are 2.25in The stock spring mount is .5in And half of my danna 44 tube is 1.375in Add that all together and you get 4.125in lift But if I add the full tube at 2.75in I get 5.5in lift which is what it should come out to Link to comment Share on other sites More sharing options...
mikekaz1 Posted January 3, 2017 Share Posted January 3, 2017 SOA lift is measured above axle/hub centerline. similar to how going from a 30" tire to 32" tire is only 1" of lift. even though its a 2" increase. Link to comment Share on other sites More sharing options...
Pete M Posted January 3, 2017 Share Posted January 3, 2017 puuuurrrrty sure you have to add in both halves of the axle tube. Link to comment Share on other sites More sharing options...
mikekaz1 Posted January 4, 2017 Share Posted January 4, 2017 Ah. You are correct. I forgot to double the equation to compensate for the mirroring effect. (1/2tube+mount)2+Springpack. Albeit it is still a known variable lift. And can be near perfectly equated regardless of weight capacity changes. Link to comment Share on other sites More sharing options...
ftpiercecracker1 Posted January 4, 2017 Share Posted January 4, 2017 Pete: LOL Ok cool, so it is just as i suspected. Going SOA with MT springs will net slightly more lift than standard capacity, not because of the difference in capacity but simply because the leaf packs are thicker. So the final equation would be leaf pack thickness + perch height + full axle tube diameter. I went out and braved the harsh FL winter (73° @ 10pm) to measure for my self. A little over 5.5" maybe 5 5/8"? Also forgot to mention I have a chry 8.25, larger tubes than a D35 right? Just for reference, here is a pic with standard leafs.
