Running two batterys make the back sloop

[mgbrandy]

Have anyone had this problem the back goes down alot with the 2 batteries in it should i put the shock ring higher or get better then stock shocks?

[jimbo74]

either.... i run stock shocks with ace hardware springs. the springs are a lot stiffer than stock... if i want them to raise the rear end, i tighten up the pre-load adjuster

[mgbrandy]

I am runing the black springs is the ones you talking about stiffer?

[jimbo74]

yes they are

the gpm heavy duty springs are good as well

[mgbrandy]

Do i go to ace and just match the size or is there a part number jimbo?

Jimbo, I went the ace route as well from your recommendation in a previous post. The front are perfect. The back, I am still having issues with. I have used 80wt oil in the rear and the traxxas upgraded shocks. I still have the rear spring pretty well tightened down and I don't get the response I would like/expect. Do you find this as well?

[jimbo74]

its been fine for me..... i also run front rockers in the rear though..... the rear end is going to sag, that what it does.... it isnt going to keep the rear end from bottoming out... these vehicles hit bottom on jumps, no matter what you do to them.....
