    Hydraulic Bump Stops??

    Just a couple of queries about these stops.
    I was wondering if they are just intended to cushion individual wheels in off road scenarios, or whether for instance they could have a role in again softening the blow for EAS cars that have dropped to the bump stops and are then trying to get home or somewhere for help ie keeping the body a little bit more cushioned. Having lost all the air in my EAS RRC LSE once on a freeway, I can confirm it is not the most comfortable mode of transport.
    I note that they can be ordered in varying psi formats, but guess that this is more akin to choosing the best shockies for individual cars/performance criteria.

    Anyone have any knowledge/experience?

    Not sure re fitting to eg a RR but we have them on some Patrols where they simply serve to absorb huge hits eg from jumping cars on or off ledges. They do limit up travel tho unless the vehicle is lifted to compensate.

    My view is they are a bit of a gimmick ..look good but not needed unless you are doing comps or silly jumps etc.

    Guess they could serve a purpose with EAS should it fail but seems a long way round for a short cut.

    Hard to fit on a stockish vehicle without severely limiting bump travel but can be used to excellent effect to limit the harshness when running out of travel.
    I can slam hard into the bump stops on a D2 or stock GU Patrol for that matter in normal driving on our standard crap secondary roads, bitumen or dirt.
    The other way to addess is this using a sophisticated shock with an internal hydraulic bump stop or using bypass shocks.
    Fox and King are good examples, the Fox IBP dampers used on the Ranger Raptor being a very good example.

    It may be worth having a look at variable-rate/progressive-rate bumpstops.
