    Hello all,
    This morning I locked my steering wheel as far to the left as possible because of an odd parking space. I noticed that my front suspension appears to be hitting the bump stops very often. I have a totally stock SR5 suspension & only drive on the street, for now. 90% of the streets in New Orleans are positively 3rd world, but it seems to me that the bump stops are getting much more of a workout than they should. Is it normal for the front suspension to have such a limited amount of travel? The front end does not seem to be sagging any. Is there anything I can do to remedy this? The only lift I have planned is the 5100s set at 2.5 with a 2" rear AAL.
    Thanks for the help.

    Since your truck isn't sagging, shocks blown?

    I don't see how they could be blown. I just broke 20,000 miles on them. They don't appear to be leaking, but I haven't really checked them up close.

    it just seems weird for street driving to bottom out. You have bilsteins up front?

    sometimes factory shocks are junk. yeah get the 5100s up front. you'll be very satisfied with them.

    So, I am not crazy. In your opinion, the only reason that the bump stops should be contacting the lower A arm would be if I was off road on a regular basis?

    yeah you should never hit the bumps on a road unless you his like a railroad crossing and jump it or something

    OK, so if I add the 5100s & increase them to either 1.75" or 2.5" will that translate into more inches between the A arm & the bump stop? Also, if I set the 5100s to 1.75", but want to change them to 2.5" after I get the rear AAL are they adjustable without removing them?

    Sorry to bring up old threads but I'm having this same problem. I have a pro comp 6" and it comes with bump stop drop brackets and it seems to be hitting every time I hit a small crack in the road. I even proved it by putting chalk on it and I could see it was hitting... I'm not sure what to do to solve this

    The bump stops are designed to prevent your suspension from bottoming out.

    Sounds like your extensions maybe too tall, if your bottoming out from a crack in the road.
    How much distance do you have between your extended bump stops and the frame?

    You may have to cycle your front suspension with a floor jack, and check if the extensions are the correct length (stopping travel before your suspension bottoms out).

    there is about around 1/2 inch between the bump stop and the LCA at its closest point.
    Explain what you mean cycle my front suspension with a floor jack? Not quite sure what id do there Lol. I know it should stop before it bottoms out but you would think the suspension would travel more than 1/2 inch before bottoming out right?

    I can easily fit 2 fingers between the bump stops and the LCA.

    1/2 inch of clearance doesn't seem like very much...

    cguernsey7,
    Just shot some video of my front suspension...even going onto a curb around town.
    Pretty boring stuff, but never saw any bump stop LCA contact.

    When I talked about cycling your front suspension, I was reffering to placing a floor jack securely under one of your LCAs and start lifting.

    If your correct, your bump-stops are going to contact the LCA pretty quickly.

    I'm having this same issue I've been looking for shorter extensions or just getting rid of them completely since I don't do heavy off roading. Anybody have anymore info on this!?

    I upgraded to the Bilstein 5100s set at 1.75. This mostly solved the problem unless the road is terrible. That is an actual issue in NOLA, though. There are a significant number of roads where doing the 20 mph speed limit will result in a wheel leaving the pavement. An additional change was to upgrade from stock to the Wheelers bumpstops. They are huge, but much softer than stock. I am now always hitting the Wheelers bumps, but it is much softer.

    I am having that front end noise as well on my 2015, they thought it was cab mounts. Now pointing to bump stops after my 4th visit to Toyota.

    I wasn't completely sold on what they told me but after reading this I feel a little better.
