    About a year ago I had front billisten 5100's installed and they were
    set at the 1.75 or whatever was suggested to level the front of my
    2008 PreRunner. The truck immediately appeared level. In the past
    4 months it appears that the truck is tilted forward again.

    Do these shocks require periodic adjustment? Any ideas?

    The springs have settled. I have mine set the same. Adjustment not required unless you want to bump it on up to 2.5 which I believe is the next setting or I think u can change out the stock coils for ebaich or ome coils then just use the coils to carry the weight for the lift.

    When you say the springs have settled, do you mean the front springs?

    If I don't want to go as high as 2.5 what are my other options.

    I am not mechanically educated enough to understand your response.

    I apologize, could you put it in more laymans terms.

    Thanks,
    Les

    The shocks don't need adjustment; the front springs have probably just settled. If you don't want to go to 2.5" then get the eibach coils. Think they give you just under two inch with stock shocks or 5100s set to zero.

    Ome 885x's will put your prerunner just over 3" with your 5100s set to 0.

    5100's "lift" the front of the truck by changing where the coil spring sits on the shock. The part that the coil sits on can be moved to sit in three different rings on the shock body, from 0-1.75-2.5.

    So, the shock itself isn't doing the lifting. By changing how high the coil sits, you're compressing the spring to lift your truck

    But, over time, since the coils were not made to be constantly compressed, yours have settled a bit, so your truck appears to have dropped a bit in the front.

    As suggested, I'd recommend grabbing a set of OME or eibach springs, and having a shop set your coil seat to "0", or stock. This should give you 1.75" of lift back, with less sag over time, and a better ride

    hope this helps

    How is it compressing the spring? If you change the mount point 2" up on the shock body which in turn raises the top and the truck 2" where is the compression? :confused:

    X2:confused: it would seem to be the other way around. I would more incline to think the shocks have settled and needs adjusting or replaced.

    each time you move up a setting on the shock you compress the coil more which in turn is the main reason the higher setting have a rougher ride

    Shocks or struts don't hold the vehicle up. They don't support any weight, they just control the motion of the spring. The spring is what supports the weight of the vehicle. That said yes they top out by themselves so they provide some support but you're talking probably <50lbs each which is negligible.

    The Billys do compress the spring because as you move the bottom ring up remember that the top hat can only extend so far so you keep adding compression to the spring because the space available to the spring gets smaller.

    For the OP if you had 1.75" to begin with and the springs have sagged 3/4" you can go up to the 2.5" setting on the billys and be back at 1.75". What happens to springs is they eventually lose their 'springy-ness' as they sit loaded up. A spring that starts out 8" long and is compressed to say 5" will over time settle out and eventually if you take the load off maybe it will will only extend to 7".
