    Hey guys,

     

    wondering if someone has tried this already or if anyone knows some measurements would be helpful.

     

    So ive run into a problem with my steering setup.  Because I’m running later model vx-vz front suspension components with modified knuckles and still running the vs steering rack I’m not getting the max amount of lock I should and its trying to extend the vs rack past its limits which is also wearing it out.  This is because the later model racks have more lock to lock than the vs rack.

     

    Im going to try and fit up a later model rack to gain this extra lock and stop the rack from wearing out.  Just curious if anyone has tried to go down this path before?  Or if anyone has some measurements of the distance between mounting points on a vx-vz steering rack?

     

    ill post any of my results up here when I get around to it.

     

    Cheers!

    With the standard VS steering gear/suspension when at full lock the inside edge of the tyre is very close to the sway bar (if running decent size/width wheels), increasing the amount of steering lock could very well see the tyre foul on the sway bar unless you have modified this somehow?

    Yea not totally sure, I  am guessing as you have mixed and matched steering components its going to be a fit a see kinda deal.  May be you use the later steering rack but have to get creative with the tie rod ends.  Interesting, please post up some pics and let us know how you go.

    But he is looking for more lock.  Only ways to do that really are different rack, or somehow shortening the steering arm lengths on the hubs to get more turn for the same amount of rack movement?

    I was thinking the same thing knowing they are different part numbers but lengths are the same. Tie rods may be longer but no measurements on site though. Steering rack might be the only option.
