    Are shocks the same length on a 2 inch lift compared to OEM??

    G'day All,

    As you will be aware, I've just had Smokey lifted. A question though...would/ should the shocks be the same length as the OEM's?? Pete and Justin who have extensive experience...don't seem to think so. I got Dobinson shocks and coils for the front. Would be interested what other's think and whether their shocks were longer or same as the stockers that came with the D2...thanks. Obviously I ask as mine were the same length:

    OEM left...new shock right



    Regards

    Stevo

    They're typically something around the same or a little longer. There are not usually any great gains in length because the shock still needs to work around all of the other limitations in the vehicle. In the D2 these are brake/ABS line lengths and the Xmember under the front propshaft. 2" springs are also not usually significantly different in length compared to an OE spring and the shock lengths will also reflect this.

    I would sweat about what you have. Actually I ran King raised fronts very happily with OE shocks.

    Hi Slunnie,

    Interesting one. Even with all the kit which had the spacers for the brake lines and so on?

    The replacement ones were exactly the same as the originals.

    The rear axle for example had another 30 or 40mm or droop travel when jacked up beyond full extension of the shocks...

    The springs were a good 2" longer (altho I agree will settle a bit)

    Rgds

    50mm is a bit, are they soft springs?

    If you space the Xmember down, extend the brake line and pull the aABS lines through and slightly alter the bump stop heights to suit the shock you could run a 50mm longer open length shock on it. Even though it will settle, the static ride height is largely irrelevant when setting the shock lengths as they need to suit the springs free length. The springs should have a load on them when the axle is fully dropped to prevent the spring moving and clunking.

    The kit maker dosn't want all of this to happen for various reasons like cost and complexity.

    It'll be the same for the rears also. You can run longer shocks to suit the lengthened effective free length of the bags and spacers etc. You are limited by the brake/abs lines but I think 4x4intelligence supplied those. The next limitation will be the Watts linkage when your shocks get to about 70mm longer or about 650mm open length. Even though the airbag will extend further it is critical that they are not allowed to reach their maximum extension - unlike a coil which will just come loose, the actual airbag will seperate from its upper section

    Stevo my shocks are old man emu and I run a 2" lift on my D2

    My rear shocks when fully extended are 625mm from eye to eye without dropping the spring when at full extension and without changing brake lines, abs or being stopped by the watts linkage.
    Mine run very well on road and have no issues with steering or handling.

    I would suggest going back to the supplier of the 2"lift and asking him for the full extension measurement of the shocks as it sounds to me you have standard shocks on there which will limit your axle when off road and will give you less than standard flex.

    Hi stevo


    stock front 330(closed)-548(open) rear 346(closed)-553(open)

    Oldmanenu front373 -601 rear 368 -584

    2" Bilstein front390 -615 rear 388 -618


    I run 2" OME springs and was impatient so used the stock shocks. The front wasn't too bad but the rear kept topping out especially on speed humps etc. Changed now for OMEs and has sorted that out but would rather the Billys

    Thats really interesting that. I'm not sure what the story is with rear shocks in D2's and clunking.

    I'd guess topping out, if running std shocks on lifted springs. (Im guessing you already know that and I have misread your question or just generally got confused!!)

    Oh absolutely, but its interesting how the rears clunk when they top out but the fronts dont. When I started running Rancho they run an internal bumpstop to prevent this so the published lengths given actually are not completely true lengths, but the internal bumpstops worked well. When I then moved to Bilstein, these shocks didn't have the internal bumpstops and I was a bit worried - but nothing.
