AAL+blocks ?

right now i have a revtek 3 inch lift and i have a rcd 4.5 coming in and i was wondering should i keep the revtek aal and put the blocks underneath. i do haul dirt bikes and boats so i like the extra payload of the aal but would the aal and the blocks over extend the 5100s?
thanks

 

i think the 5100 are good until you reach 3" or rear lift then you need extended rear lines and the 5150's

 

blocks will cause axlewrap

 

ya i already know that but thats what the rcd comes with. i will get a leaf pack later

 

i dont see where it would hurt anything..

 

5100's can only accommodate up to 2" of lift in the rear.

 

i asked the same question a while back and heard that blocks added to an AAL will flatten out the leaf pack really quickly. i havent seen anything personally, but it did come from a credible source. thats my two lincolns
