    Well,
    I just filled my truck bed up with dirt. Those that live in VA know this is not regular dirt, but more like clay. Anyways, I have no bottoming out issues and it still drives like a charm. I need to step on the brake a little bit harder to stop, but that's physics at work. Anyways, the different PN for the rear springs seems to have made a difference. I don't know how much weight is back there, but friggin red clay is pretty dense and the bed is packed full of it. Just thought you guys would like to know.

    I have had my 08 with about 400#'s in it and as you say I can feel the power loss and it takes a bit more braking but I did not notice any bottoming out or even a backwards rake to the truck.

    Seems some 08's have the bad ones and some 08's have those that are OK. It's really a crap shoot whether you get OK ones or bad ones. I think Toyota's spring vendor has some quality control issues.

    My 08 had the letters ++CHI-48210-04550-F-RH and ++CHI-48220-04190-F-LH (old parts) on the original three leaf total rear springs. I was thinking F for new firmer ++ springs as well. Not so. I have a Jan. 08 built truck and 3 leafs at that time still meant not right in my book and apparently with the dealer as well or they wouldn't have done the TSB.

    The 3 leafs were replaced with the four leaf total rear springs. I never hauled anything heavy with the original 3 leafs. I just got the TSB done before I actually would be towing and hauling with the truck. I think the truck rides better with the TSB springs. I haven't seen addition of the 08's to the TSB yet. Nor anything in writing that heavy duty 3 leafs were implemented into production to do what 4 leafs will.

    Yeah...I talked to the dealer near here and they looked at the TSB and told me that it didn't apply to the '08's. They won't even talk to me about it until I have a problem at this point- but it's cause the stealerships service guy was a moron so I was a jerk in return.

    I've gotta look at my springs and see what I can find- Cause I have the three pack in a Feb '08 built truck. My bike is going into the truck tmrw...so we'll see.

    Thanks for the numbers.

    Noticed all of you have DC's as well. Klown you mention different PN on the rear. Your #'s are different than 48210-04550-RH and 48220-04190-LH?

    Just curious if all still have the 3 leaf total rear springs? Would also like to know build dates as well?

    Thanks in advance

    Should have pasted from the post above. Mine were ++CHI-48210-04550-F-RH and ++CHI-48220-04190-F-LH (old parts).

    From what I've read elsewhere is that same part numbers is same parts period. The other markings are dates and plants where built, ect.

    I looked at 08's at the dealership yesterday. They are the same 3-leaf pack.

    I got the TSB and put a rear sway bar on my 07. Very happy with the results :D

    I don't know the PN right off, I thought my PN had an "F" at the end. I'll have to double check. Yeah, this is still a 3 leaf set up. My build date was Jan 27, 2008.

    As somebody already stated in this thread. I think all the PN's are the same, the other #'s may be lot #'s or date codes or place of manufacture. It seems like it's a quality control issue. Some springs are shit, while others are DA BOMB! I'm getting more dirt today, Yesterday I got one scoop of dirt and it filled it up really well. I'm gonna push the envelope a little and get 1.5 scoops. I'd say it's about 1200 lbs of dirt. I might chicken out at the last minute, but I'll keep you guys updated.

    My truck bottomed out with myself and 3 other pasengers in the truck so I had toyota replace the leaf springs. It also almost bottomed out with a light load in the bed 300 to 500 pounds.

    Well I just went and got 1.5 scoops of dirt in the bed. It's 50% more then I did before. Sure enough, no bottoming out issues yet. There are some railroad tracks on the way to work that I ran over, didn't bottom out on them. We'll see how the drive home goes. So far I'm impressed with the stock leaf spring setup.

    It Seems That The "off Road" Modles In 08 Came Equipt With The Correct Leafs. My 08 Sport Just Got The Up Date And Needed It. Bottomed Out Owith One Bike In The Back Over A Speed Bump.

    I would like to have it done just in case..I don't want to have to fix a problem, I prefer preventative measures... Of course I called the dealership service dept last week and left a msg, no returned call!

    The part ##'s on the 07 & 08 are the same, If the 07 was not "to par" one would think the same part on the 08 would also be substandard also.IMO

    I took have pics of mine in my photo's to show part ##s

    I agree :)
    Not nesaserily. They may have the same part numbers, but they may have changed how/where they are manufatured, thus fixing the problem. :)

    I'm not sure if I want it done unless it's NEEDED. I like the stance of the truck as it is, with the TSB the ass end comes up, I'm not a big fan of that look. Of course if I find it's needed to haul stuff in the bed, then I'd get it done. So far, every indication I'm getting is it's not needed on MY particular truck.

    I bought an '08 DC TRD Sport with the tow package last weekend and hooked up my 3500 pound Winnebago and it didn't sag at all.
