Ok I can definately say that this has been one of my better purchases. I picked these up from JC Whitney were they are now on clearance for $99.00 and this was well worth it.

Installation is pretty easy and straight forward. just a disasembly and reinstalling the progressives and adjustable collar in place of the original spring.

they are stiffer then stock even with zero preload on them, I tried them with half preload and it was too stiff for me but im a pretty lite guy. with half preload they seemed to pick up the little stuff more, and I was hoping they wouldn;t however, on firday night I went to hit my favorite jump. its a small 1 ft jump but its on top of a 5 foot ledge. previously when going off this jump the landing would be harsh, I have pictures of the stock suspension completely buttomed out at landing and it would jar me really hard when I would come down and the suspension would bottom. now I simply landed and had no bottoming out just some suspension action and I'd keep going.

the next test was saturday in the whoops at a different riding area. previously I could go across the smaller ones but the larger ones would turn the quad into a bucking bronco. and I found myself laying on the handle bars a couple of times. on saturday i ran zero preload and was able to go across large whoops at almost full throttle always maintaing control and with no bucking bronco action. I also found when I would be flying through a trail and come across a ditch made from run off, it doesn;t "hit " the bike as hard and almost cause a loss of control, just a quick bump and im still going down the trail. smaller bumps were no different then the stock springs.

I would recomend theses springs to anyone, that encouters jumps or whoops

just figured I would post this if anyone else was interested and incase the questions was searched in the future. I feel these springs are worth the money.
