    Hey guys, I've just put in my bilstien 5100 shocks and rear TSB done. I've having issue with my suspension now that it's much harsher than before. Meaning that the rises is way worsen than before. If I hit a pot hole or and uneven road with bumps, my car jerks and bounce left and right. Is anyone having the same issue I'm having. And I also have a vibration at speed of about 35 to 45 mph. I think that even with the new shock lift it should jerk my car that much and even going on uneven roads, I should still be able to control my car. anyone with info, please let me know cause it's frustrating me now. Thanks

    Did you get an alignment after installing the 5100's?

    A lot of people on here talk about the vibrations... not sure though w/ just billies. The jerking left and right is def not common though.

    ^^^Agree with him, you have an alignment?

    What were your alignment specs? Do you have aftermarket UCA's?

    Yes I did. When I drive the car through uneven rough streets, I feel the car just jerks around and seems like the suspension is way too stiff and it should still give me a comfortable rides after putting in the 5100's. If I hit a road bump on the freeway, my car seems to roll or bounce uncontrollably, any thoughts would help.

    Hmm did you get a printout of the alignment specs sheet? Sounds like your caster may be out of whack.

    Do you have stock UCA's?

    Seems odd...

    I have 5100's set at 2.5 and a 2" AAL w/ stock UCA's. They set my caster at 1.9 and it rides great. It wanders a tad more than stock but IMO my truck feels much tighter after the new suspension.

    Post your alignment sheet numbers.

    Think about it.. your front springs are compressed so much at 2.5 that it's going to be harsh. The spring needs some give for it to compress and extend to keep the tire on the ground. I wouldn't lift it any higher than 1.75 with stock springs... I had mine at .85 and the ride was similar to stock... less body roll, stiff but not harsh.

    try lowering the height and see if that makes a difference, if so you on the right track.

    I'm at 2.5 with mine and the ride isn't harsh at all. Slightly firmer than stock, and I mean slightly. I have ridden and driven in some harsh vehicles before. I used to be in the performance car scene. I had a honda accord w/ a 3" drop so I know harsh suspension. My buddy used to have a subaru WRX with JIC Magic coilovers. I would make sure I peed before I rode in his car because it was sooo stiff it would make you have to pee if you had the slightest amount of liquid in your bladder.

    Hmmm... could be you have a set of bad shocks then?

    That would suck.... Push down on the corners of your truck and see if the suspension pops the truck back up in a timely manner.

    Hey, yes my caster is set at 1.9 too and I did the same setup as you did. 2.5 and TSB in the back and stock UCA's. Just don;t know why my car is riding this way at all.

    When I push down on the front corner of the car it goes up and down slightly, not much.

    You guys also have pretty shitty roads up there compared to GA so maybe thats the issue. I was in minneapolis last May on business and the roads were definitely worse than down here.

    Are the spring perches installed correctly? It's a common mistake on the billys for people to install them upside down. That would preload the springs a lot more and give you a stiffer ride.

    Yes and correct, our roads are here are just ridiculous due to the winter snow and stuff. All the freaking payments is like crap here and there's pot holes and uneven payment every where you go. But the weird things is that I have a friend that drives a 09 tacoma dbl can 4x4 and he has the same setup as mines and it runs really smooth than mines, just odd.

    I double check mines and I know I had them on correctly.
