    I have tried to search for an answer to this, but I have a specific question I'm hoping someone can help me with.

    I bought a well-maintained one-owner 2017 Tundra Crewmax limited. The front end had 1.5" spacers which I got rid of and replaced with Bilstein 5100 adjustable struts set on the highest setting. I'm very happy with that.

    The rear leaf springs appear to be sitting on a 1.5" spacer and have the original Bilstein 4600 shocks. The rear end appears to have extra lift as compared to stock and the springs are not flat. My question is, are the stock 4600 shocks somehow limiting the extra height and/or ride quality considering the 1.5" lift spacer under the leaves? When I read posts about the rear end people mention going to Bilstein 5100's, but when I research 5100's for the rear I find that there are different varieties. I'm looking at replacing with the 5100 "for a 2" lift" part number 24-286244.

    Please don't introduce other variables like shackles, etc. Would the truck benefit from the 5100 rears made for a 2" lift?

    The only way to lift your rears is through shackles or blocks, which in your case is a 2” block spacer.

    Shocks are rated for X inches that increase up travel or down travel. Lifting your rears without the properly rated shocks can prematurely destroy the shocks.

    Thanks Phuc. I think you've confirmed my suspicion that this was a half-a** solution and I should get appropriately sized shocks to switch out the OEM version.

    Why no shackles? They are easier to replace than installing the blocks (only 2 bolts per shackle), they keep a better driveshaft joint angle than the block, which prolongs life of the joint.

    I have 5100 in rear and +1" shackle.

    Has OP considered shackles?

    I'm not opposed to shackles, just tackling one variable/question at a time. The previous owner had the blocks installed, not me.

    For those that have shackles, do you also have the TRD Exhaust? I'm reading that the shackles interfere with the exhaust. So if you have both, which brand/model shackles do you have? I can search that as well...Thanks

    TRD dual exhaust. There isn't more than one version of the TRD exhaust unless I am mistaken.

    Blocks aren’t half assed, and a lot of guys do use blocks.

    I went the shackle route for off roading purposes. Blocks wouldn’t last.

    I didn't mean that blocks are half assed, rather that not replacing the stock shocks when lifting the rear was half assed. In fact I think I would be fine to keep the blocks, they're only 1 1/2" anyway, but I do want to go to a larger shock because of the added 1 1/2". I don't do much off roading aside from the typical needs of living in a rural area.

    Lol gotcha. I’d say the best way to go is with a shackle though.

    I would get longer shocks that are intended for lifts. 1/2 inch to maybe an inch block would be okay with stock shocks but not 1.5 inches IMHO.
