I have a 2006 Z570 and the rear suspension needs some work. I would like to make it more heavy duty to handle heavy loads...okay, my heavy load. Anyone have suggestions? Is there a different spring other than the stock style that I can put in? What about the shocks?

Call Counrty Cat "Catbargains.com" on the web. They sent me heavier torsion springs for my wifes Z570 since she rides my F6 and I was bottoming out her Z. You will have to call them but they will get them to you in a matter of days. With the 2006 most of the ZR springs work but I would call, they knew what I was after right away. Also while you have them ask if they have any ACT shocks for the rear arm. I put on a new in the box ZR clicker on the rear arm. World of difference.

Jus tput heavier springs on wife's '06 Z570LX. Haven't ridden it yet but the part numbers are 704-944 and 704-945. Hope this helps.

springs will help a little but im pretty sure that on the trail sleds cat puts ride fx shocks in there...which isnt rly that good...if you do it get new shocks and springs...or if you can just find a skid with all shocks and springs out of a zr 8,9 sno-pro or cross country...its another way you could go since ppl said 2 get beffier springs...
