    I haven't done anything yet, just looking at any issues that might come up, and how far I can safely move the front forward. The space between the drag link and the tie rod, measured at the center of the frame, front to back is 3/4". At the center, looking rearward the DL is directly above the TR, with no gap visible. What do you guys think, how far forward could I go? Any other things for me to consider?

    I moved mine forward an inch with zero rates, and i don't think I could go too much more with the stock D/L. Mine is adjusted almost all the way in /forums/images/graemlins/eek.gif /forums/images/graemlins/peace.gif

    Sounds tight. I was thinking of putting the tie rod in the front and moving the axle forward 3.5" to clear the tie rod and the drop steering arm.

    How close is the Tie rod to the steering arm now when your flexed?

    Oooo, good point! I better put it on the ramp first and check that distance, I don't remember how close it is...

    I redrilled my perches and plates for 1 inch forward and didn't have any problems. Then I made the stock draglink as short as possible and it drove on road fine. I never did get it offroad before I switched over to x-over steering. Now with the axle moved forward I haven't had to bend the x-over draglink to clear the engine cross member.

    Yet another reason I stuck with low steer. Sorry, not much help other than "back to the top".

    No help here either other than posting a link to the webshots photo album with the pics.

    Hmm, another thing that comes to mind (depending on up travel) is a straight drag link. I've never liked those bent ones anyway...

    Well, put the beast on the ramp. I've got 1 1/4" between the DLE and the tie rod at full left stuff. So it looks like thats all I'm gonna be able to go, without changing the steering (which I don't want to do). I need to keep the drop DL, otherwise I'll be into the crossmember.

    Funny thing about moving the axle foward... A strait DL often clears when the axle is moved foward. The strait DL seems to put more bind on the ends however. I say keep the bent piece, I see you have the WTO ram back on, that makes the stress on the DL bends a lot less.
