    hey all, i gots another rear spring tsb question... :mad:

    has anyone confirmed is the 3 and 4 pack leafs are the same spring rate just one more leaf? it is essentially a factory AAL, right? (new here, took me a few min to figure wtf everyone was saying when referring to aal...) or are each leaf thicker on the TSB pack?

    i called the dealers by me, they all want me to bring the truck in "loaded" so they can inspect it. seems like a waste of time, only to get denied. i have an 11 AC, and i ordered 5100's with 16x8's and duratracs. i only want to align it once, so i want to get it done in one shot.

    my question essentially is: if i get a wheelers 1.5 AAL, that is essentially the same as getting the TSB done, correct? for $100, i can have it done asap, rather then dicking around at the dealer trying to get a pair of springs, no? i was a mechanic for 15 years, so the install will be a sat afternoon for me.

    thanks in advance, and sorry about another tsb question... i searched but there are a billion threads, none of them seemed to answer my question. :)

    oh, awesome site btw, :cheers:

    I don't think anyone has measured the spring rate of the TSB packs (at least not that I've seen).

    I measured the OEM 2009 leafs on my AC, although not a perfect test, and found that the overall rear spring rate is about 600 pounds per inch of deflection (300 lb/in for each spring).

    They are different spring rates.

    are you referring to the leaf pack? then yes, i would assume they are. but are the leafs the same size, just 4 instead of 3?

    I've hauled 1000# of mulch before and after the TSB. The truck bottomed out a lot before the TSB but not after. The truck also handled much better after the TSB, less wallowing, etc. Maybe with time the springs will soften but at the moment, the TSB springs are MUCH better than stock.

    some crappy dealer installed lift , 285's, trail pin striping, and a grill full of lights.
    My truck still sags pretty bad in the back with the TSB springs, but now instead of riding on the bump stops it sits on the overload spring. As someone else said the ride is much better empty though...

    I haven't bottomed out with the TSB pack but it flattened out in a hurry. Within 30k miles, it was sitting on the overload and rode stiff as hell because of it. I've since put in another new TSB pack I purchased from a member here and put the Icon 3 leaf AAL in there also. So far I'm very happy with the results but, as mentioned above, the stock leaf packs suck on their own!

    Check out my sig...
    Might wanna watch out. if you modify the front suspension the dealer may not wanna do the TSB. I think that happened to someone else on here previously.
