    The TF Expeditions that were replaced are still fine, sitting on the shelf.

    Really want to bring this bounce under control before the Simpson is 10 weeks, but a $1000 a pair for the Raids it's a bit exy to run twin Raids, but it may be the only way.
    I would suggest they just need setting up properly, it might be worth booking it in with a suspension expert such as ultimate to see if they can adjust the valving to take out the rebound.

    I find it hard to believe that won't control it, but if it isn't enough send them to either Proven Products or Toperformance to get them revalved, it's pretty cheap and easy.
    What about spring Rates?

    Surely shock valving has to work with the spring rate in the vehicle. Then that would also lead to making sure the spring rate is good for the given set up...

    Not quite sure what you are getting at ?

    You adjust the rebound to suit how the chassis is reacting.

    If he's happy with the load carrying and ride, yet the back end is rebounding too strongly after a big bump, increase the rebound on the Raids.

    It's pretty simple.

    No, it doesn't mean the spring rate is optimal, but that changes on application.

    They are externally adjustable, no need to take to a shock place unless he's at the maximum adjustment already.

    Seriously, if you're doing the Frenchline you have no idea just how badly you want to address this issue - it's an endless series of wheel scalloped holes.

    I wouldn't hesitate to run two different types of shocks on a dual setup - any force differential would be easily within the margins of the overall design brief.

    The koni raids outer case diameter is too large for the dual shock mounts. You will not fit two koni raid together on one side. There is about a. 10 mm gap between the two bilsteins.

    can someone sent me some pics how the front dual shock set up looks?

    I saw the back TF brackets but wondering how the front would look like.

    Just pulled them out to double check the adjustment and yes they were both on full hard.

    I also have Poly-Air bags in the rear, is it possible that these air bags are contributing to the bounce factor.

    If not, I guess I will just have to follow up with ultimate suspension on Monday for further advice on re-valveing.

    I really thought the Raids would have muscle to sort the bounce out.

    There's a ~22mm gap between 46mm Billies on the Terra Firna twin rear mount - just had a look.

    The Raids are 70mm in the body and 85mm for the dust covers - so won't even go close.....

    But on a positive note, a search of the forum found a KONI PDF, posted by Rick130 in July 2013. It show that the compression and rebound rates/pressures can in same cases be 500% greater from one Raid to the next.

    It seems that KONI determine the "appropriate" specs for the particular vehicle, but the shocks are capable of much much more.

    So, re-valveing appears should be solution.
