    I leveled my 2011 platinum by lowering the rear using TR.325 kit from SOS.

    They offer Bilsteun rear shortened shocks for this kit. Can't find part# to see if it's available somewhere else.

    Anyone used these or know the part# for these Bilstein shortened shocks?

    Thanks

    How does the drive feel compared to stock height?

    I have a gently used pair available from my lowering kit if you are interested?
    They helped a lot while lowered.
    Also have some Caltracs and helper bags.
    Attached is a photo with the part number and of the shocks I have available,

    What I did was looked up Monroe shocks for the tundra, noted compressed length, extended length and top and bottom mounting types. Then went to their complete catalog with specs. And was able to find a set 4" shorter with same top/bottom mounting points.

    Ride is comparable to stock with black Toyota shocks.

    Also added sumosprings , had to cut them 1" shorter but they work great dragging car hauler.

    Have that part number handy? I've lowered mine with the SOS 2/4" drop and added the yellow Bilstien B6 4600 shocks, but the ride is a little stiffer than I'd like with those shocks.

    SOS 2.5/4.5” lowered (pending 3UR-FZE)
    The Bilstein 4600 shorter shocks are from an F150 on 24-024792. Just got a confirmation from another SOS kit owner.
    Hope this helps any future buyers. You can source them yourself for a lot less than SOS.

    Calvert also has a shorter shock for lowered gen 2s according to another forum: Calvert Twin tube 42133
