ProComp vs Alcan Add-a-Leaf
 

What are the differences between these 2 AAL's? I know the ProComp is stiffer, but what other advantages could I expect from the Alcan?

i think the alcan is longer. so its a softer ride. i have the alcan AAL and its not too stiff and does what i need it to do with the lift. ive heard bad things about how stiff the procomp is. id say alcan all the way.
