    I'm getting ready to have the 5100s and the Icon RTX leaf pack installed. I'm not going for a lot of lift, but was hoping for 2-3" in the rear and then about 1-2" in front. I want to restore some rake and load carrying with my shell.

    Everything I've read said the 5100s only range from 0-1" in the rear so that seems a problem. I just learned that there is a version for 4" or more.

    https://www.bilsteinlifts.com/shop/...-bilstein-5100-shocks-for-2005-toyota-tacoma/

    Has anyone used these? Will they work for less than 4"? It seems odd that the only option is 0-1" or 4" or more. What about the 1-4" range.

    Yup. 5125s come in two varieties. I have Part Number 33-230337. The longer ones are Part Number 33-319070. You would likely need longer bump stops and brake lines for those. Also, the provided sleeve is likely too wide for the lower mount. I did the Hulk Smash to get mine in, but I would recommend the easy route of trimming the sleeve down to fit the mount.

    Stock Bilstein Rear shocks
    - Collapsed length : 13.98
    - Extended length : 22.94
    - Travel: 8.96

    Extended length 5100 B110 specs
    - Collapsed: 16.34"
    - Extended: 27.28"
    - Travel: 10.94"

    5100 specs
    - Collapsed: 14.02"
    - Extended: 22.94"
    - Travel: 8.92"

    That means stock vs B110
    - Collapsed: 2.36 longer
    - Extended: 4.34" longer
    - Travel: 1.98" longer

    I think a lot of folks here run the B110 with 2-3" of lift and are just fine. What you want to check is that the bump stop in hitting before you bottom out the shock.

    Headstrong lists them as 3"-4"

    So 5125 is a 5100 with more length and then a different 5100 with even more? Would make more sense to have different numbers for them all.

    I have sumo springs. I'm assuming those would be tall enough to prevent bottoming out. Not sure how much they can be compressed though.

    Yeah. It confused me even after I installed them. Thankfully, I had good folks out there looking after me.

    Since the 5100s are spec'ed for 2005 to current, the typical 5100 is the same as our stockers but gives the 2nd Gens +1in of travel.


    The Sumos are likely taller than the stock bumps but compress very differently. What I did to confirm was flex out my suspension with the shock disconnected after the RXT (Option 1) were installed. I found 2.75in of travel beyond the stock shocks. A bit of parallax in the pic.

    If you go Option 3 (max lift), you will have a thicker pack to consider in relation to the bumps. With the Sumos, you might be okay, but it is good to check.

    Thanks. I'm assuming that means a bump stop of at least or maybe a bit more than 2.75" is needed to keep from bottoming the shock. The Sumo springs are a lot taller than stock bump but I don't know if they can compress to less than 3".

    Yeah. It is hard to tell. You can flex out your current setup to see how much they compress. You will get more dynamically, but unless you are really running hard and fast, I don't think it would be more than a full flex. Of course, if you are running high speeds in the desert, the 5100s / 5125s might not be the right answer. Haha!

    No, I'm not planning to be flying off sand dunes or anything. I mostly drive rocky roads at slow speeds. I'd probably land on a rock before the rear slams the shock.

    That is pretty much my usage.

    And, my apologies. I got side tracked yesterday afternoon. I will get in there today.

    Info I also needed to know for my OME spring install. Thanks! Was hoping to be able to use the rear 5100's I have now but guess not.

    Keep in mind the 5125 shock mounting points are meant as a universal setup. Whereas the 5100 are model specific

    Cheers!

    Yeah. You will be missing a lot of down travel with the 5100 rears.

    I do not understand this? The 5125s have the same upper mounting as the stock shocks. The sleeve for the lower mount was too wide, but the shock itself fits fine. Just trim the sleeve before installing.

    If you are talking about the valving, the match between the front and rear feels incredibly good. That was one of the funny things about my setup. Ordered late July and the parts all came in at different times. The RXT packs arrived right away. I couldn't resist tossing them in. Huge improvement right there. Then the 5100 fronts came just before a planned trip. Swapped those in and got an alignment. They solved some problems that I was having with the worn out stockers. From there, while waiting on the rears, I took a 4,000mi trip. The handling was really good, but every so often, I would hit a bump that felt weird. I chalked it up to the budget direction that I went ($1,100 all in). About a week after I got home, the 5125 rears arrived. I was surprised to feel it all come together. That odd feeling over random bumps was gone.

    And not only that, but the RXTs also feel great when driving around with my usual 200lb of stuff in the bed removed.

    Are you referring to the larger bushing and sleeve for the bottom mount being to wide? Or is there something else also?

    5125 come in many different lengths and travels. And some need an adapter to mount up properly.

    Yes. There seems to be five different 5125 parts. I would like to get more data on them, but only two are known to me ATM. The Part Number that I listed was what I used. Part Number 33-319070 is the longer travel that @phdog is asking about. I have not physically seen that one, but the pics look similar to mine.

    Shocks should always be decided on based on what type of travel your current or planned leaf setup will provide. I think the 5125 provide and additional 1”-1.5 on collapsed or extended travel over the 5100. Hence why you see many people with AAL doing fine with just standard length 5100s. Again, a lot depends on your use and current leaf setup

    That is sort of mostly true, but the biggest problem is that the standard 5100 rears, which I originally had on order, had the same collapsed and extended length as the stock shock. A friend pointed this out and told me to check things before they were sent. That is where my pic above comes from, with the stock shock in the pic. IMHO, anyone going for 5100s and adding travel in the rear should get the 5125 rears or they are limiting themselves needlessly. The +1 over 3rd Gen stock 5125s that I got (Part Number 33-230337) work perfectly with the RXT Option 1 leafs and the stock bumps. I can see the bumps putting witness marks on the frame after flexing. The +2 over 3rd Gen stock 5125s (Part Number 33-319070) would have likely needed only a bump stop change and would have allowed the leafs to be the limit for down travel. When checking my brake lines, both parking and service, they had no issues at full droop with the shock disconnected.

    The OP is looking at the RXTs and the longer travel while already having Sumos. I am assuming that he will go Option 2 (same pack thickness) or Option 3 (slightly thicker pack). Option 3 would make the Sumos slightly more effective.

    You are right. Folks need to do a bit of homework. I feel the 5125s are the better solution with that homework. 5100 rears are plug and play, but are too limited.

    well said. I don’t know why we don’t see more 5125 or extended 5100 posted here or discussed as much

    Which would you recommend paired with and OME HD pack. Trying to use stock bump stops and brake lines but will go with extended brakelines if needed. This is on a 2nd get for what it's worth.
