MJeep Posted September 17, 2012 Share Posted September 17, 2012 I know that its another leaf, but with the MJs being SUA, wouldn't it just push the axle up lowering the truck? Link to comment Share on other sites More sharing options...
Eagle Posted September 17, 2012 Share Posted September 17, 2012 No, because the additional leaf increases the carrying capacity of the spring, causing it to bend less due to the weight of the vehicle. Some AALs have more unloaded arch than the leaves of the stock springs, so they actually force all the veaves to bend (arch) more even before weight is applied.

Geonovast Posted September 17, 2012 Share Posted September 17, 2012 Adding an extra leaf to an SUA vehicle doesn't move the axle... the axle is still sitting directly on top of the main leaf, and all the addition leaves go under the main leaf. When adding an AAL to an SOA vehicle, yes, the thickness of the leaf adds height. Link to comment Share on other sites More sharing options...
MJeep Posted September 17, 2012 Author Share Posted September 17, 2012 So an aal with a sua will provide lift? Link to comment Share on other sites More sharing options...
mountainman Posted September 17, 2012 Share Posted September 17, 2012 So an aal with a sua will provide lift? yup. Like they said, re arching the leaves puts the curve lower down. The axle comes down with that event. lifting the truck. Get it now? Link to comment Share on other sites More sharing options...
Eagle Posted September 17, 2012 Share Posted September 17, 2012 So an aal with a sua will provide lift? An AAL generally produces lift regardless of whether it a SOA or SUA. For example, Rancho sells the same full-length AAL kit for the Comanche and for the Cherokee. It produces about 2-1/2" of lift in a Cherokee, and about 1-1/2" of lift in a Comanche. An AAL is not just a spacer. It's an additional leaf in the spring, and how much lift it produces depends on how strong it is and how much arch it has. When I bought my '88 Comanche it had a Trailmaster 4" lift in it. The rear lift was from a short AAL kit, nothing else. Link to comment Share on other sites More sharing options...

sinkrun Posted September 17, 2012 Share Posted September 17, 2012 While were on the subject is there a difference in Cherokee and Comanche AAL? If yes how can I tell them apart I have a set that was included in some trade stuff and not sure what they are. Link to comment Share on other sites More sharing options...

If yes how can I tell them apart I have a set that was included in some trade stuff and not sure what they are. That depends on whose add-a-leaf. Rancho, for example, sells only one AAL for both vehicles. There may be some companies who have a special AAL kit just for Comanches, but I don't think I have ever encountered one.

MJeep Posted September 18, 2012 Author Share Posted September 18, 2012 I get it now, thank you all for clearing that up, for some reason i just couldnt wrap my head around the SUA AAL concept Link to comment Share on other sites More sharing options...
Blue88Comanche Posted September 18, 2012 Share Posted September 18, 2012 how do i go about adding an AAL? I have my old 4wd leaf packs I was thinking about using to add to Dad's MJ leaf packs.. is it just a matter of unbolt and re-bolt? Link to comment Share on other sites More sharing options...
