    I've spent almost a week pouring through the various threads covering rear suspension but the more I read, the more I get overwhelmed.

    I have a 1st Gen Tacoma, so I'm familiar with the platform in general.

    I'm buying my co workers 4Runner, 97 4x4, and it's stock.

    I plan on installing an extra set of Icon UCA's and King EXT 2.5's that I have onto the 4Runner and getting rid of a bit of preload for a 2" lift up front.

    I've seen LC, Dobinson, and a few other rear springs people normally use but they are for 3-5" of lift; how do you even lift that high without sacrificing the front axles to level it out anyway?

    I digress; I'm looking for a quality rear coil to provide 2" to 2.5" of lift in the rear while sitting on stock weight.

    To follow up with that, I don't only want the lift but I want the extra droop/travel and it seems that 2 springs providing the same lift, don't offer the same travel? That's where I need help.

    Also, what shock length would I be looking at for the rear?

    Example; on a 1st Gen Taco the stock shock travel is 8", and uses roughly a near 13" collapsed length and 21" extended length.

    My truck sits on Fox 2.5 up front, Fox 2.0 9" in the rear, and OME Dakar's.

    The 4R will be an off-road rig as I'll turn the Tacoma into a daily.

    Here's the Taco -

    Don't have pics of the 4R as it isn't mine yet; waiting to do a transfer of something else.

    For 2-2.5" in rear, OME 891 or 906 coils. the 891 would be my choice. :hattip:

    Thanks for narrowing down to those 2 coils; looks like the 906 are more commonly used especially for my setting.

    Read several instances about them falling out though during massive droop due to the springs being really short; seems people just use wire or brackets to hold the coil in place.

    I take it no coil exists that can handle the 'Tundra' shock length, while still only providing 2" of lift right?

    Up travel seems to be an issue when dealing with springs and limited height over stock...

    I assume you meant 'rear Tundra' shock length. I would compare it to a shock made for this truck. My favorite rear shock for this truck, Bilstein 5100. Designed for 2" lift. Part #24-249966.

    5100:
    Extended Length (IN): 20.79 Inch
    Compressed Length (IN): 12.91 Inch

    Tundra:
    Stock (Bilstein 4600) TRD shocks.
    Collapsed length: 14.98 in
    Extended length: 24.45 in
    Travel: 9.47 in

    I get that.

    I guess what I'd like to see is;

    A shock capable of 13" collapsed length, similar to the 5100's you posted. This means the shock can fall short enough to not require extended bump stops.

    A shock that provides 8 1/2" to 9 1/2" of travel.

    A coil for the rear that has enough length to support said shock, without falling out during full droop, and without lifting the vehicle excessively (2").

    Seems one could go for the shock you listed, but droop and overall travel will be limited. I can see how the OME 906 will compliment this shock well.

    Just wanted to get more rear travel than I normally do from my Tacoma.

    On my tacoma I went with bilstein 5125. Just like 5100 yet more travel and much more droop. If they make a 5125 for the 4runner, that might be an option. Good luck and see you on TW. ;)

    I’d shoot Dobinsons a email and let them know what you’re after as far as lift height and load and they will spec you out a set of coils. I did just that and ended up with exactly what I wanted. I was using factory replacement coils with a 1.5” spacer and when I added a drawer system and fridge it sagged a bit. The new coils I ordered were on the money with lift height and load rating.
