do yall think that leager long travel a arms and Elka ZPS shocks will work with a stock rear shock, kinda curious

 

if the swing arm is stock then the stock rear is fine but it all depends on what and how you plan to ride with it

 

It's been my experience that you end up with a nose low attitude which will upset the quad badly.You can put all the pre-load into the fronts to raise it to meet the back but you lose the advantage of the lower ride height and some ride quality.The Z400 needs a longer swingarm(but we'll probably never see it stock).I would buy all 3 shocks (and the linkage if you go with ELKA).JMO
