i was wondering if anybody found a really good rear suspension setup. i`ve got a 01 zr 600, and hitting a bunch of big bumps sometimes doesn`t feel to good . i`m a little under 200lbs with all the gear on. also when the sled is on an incline, the front up hill, the rear suspension sags. i can lift the back bumper up several inches, before the track comes off the ground. i was worried at first because i got stuck and found out about this, and i thought i had broken something . but after letting the snow melt off, i couldn`t see any broken springs.
