    1999 Ext cab with 3400 V6

    Has Deaver J59 rear springs and Bilstein shocks
    I was going to replace shocks and Bilstein site lists 33-247717 as what I need

    But when I checked numbers that are currently on it has 33-185606

    I don't want to order something that I have to send back so which is right and if they will both work which ones are better?

    I guess previous owner could have put whatever would fit on it instead of what is right?

    Is there a better option/brand at similar price?

    Thanks

    On my phone, but give yourself an extra minute and I bet you'll find the difference between the two is either -

    One is almost an inch longer than the other

    Or

    One is an older variant whereas one is slightly newer

    There are 3 different Bilstein 5100 rear shock part numbers that all work with lifted Tacoma's with the slight differences explained above.

    All work fine.

    33-247717 is the 5100 series shock for our trucks. That was what I installed on my truck 2 years ago. The shock you have on there now is a 5125 series shock. See this chart:

    5125_size_chart.jpg

    You might notice that the 5125 comes in several different valving options. Depending on how you use of the truck you might like a softer or more firm shock in the rear end. I came across this thread a few weeks ago and swapped out my 5100s for the 170/60 valved 33-230443

    https://www.tacomaworld.com/threads/stiff-rear-end-after-lift-you-got-the-wrong-shocks.471164/

    For my uses I like the softer valving better, someone who drives on rough roads might like the 255/70 valving better.

    Appreciate the help

    What site is that chart on? Wondering if they have one for 5100 series that shows same details.

    The best place I've seen for specs on the 5100s are Headstrong. I made a spreadsheet a few months ago comparing a bunch of the rear shock options and Headstrong was one of the more useful websites to pull info from.

    Thanks

    First question is the headstrong link shows quite a bit of difference in collapsed and extended lengths between left and right sides?
    Any idea whether the 5100 is on the softer or stiffer end valving wise?

    The 5100 is the 255/70 valving, I find it a bit harsh with an unloaded bed driving on road. I am liking the 170/60 valving better personally.

    The difference between left and right I believe it due to the difference in ride height, the gas tank and battery are on the drivers side so it has a tendency to ride a bit lower. Some rear suspension offerings seem to account for this (Dakars) but it does seem like a lot of people end up installing the same shocks on the left and right side in the rear.

    Interesting.

    I found the valving in the 5100s to be really soft.

    I would actually swap rear shocks depending on what I was doing or where I was going.

    When I carried my rear swing out and tube bumper (not much weight over stock), I needed to keep my 5100s on -

    It wasn't until I'd add over 150lbs in the rear to go camping (bed rack and RTT) that I'd need to switch back to my Fox -

    After said trip, the 5100s went back on.

    Nice thing is, it takes like 5 minutes to swap rear shocks.
