94 vmax rear suspension upgrade

[bks81]

Well heres an update on the Xtra-10 skid install and all the adjustments I did to it. I took the sled to the U.P. in January and put about 300 miles on it in 3 days. The sled rode great on the groomed trails, of course. There was 1 day that we rode where there were a lot of moguls because the groomers just couldnt keep up. The sled handled the moguls probably as good as most sleds. My wife was riding our 98 Cougar that has the ETT 13.5" track travel and she was hurting more then I was by the end of the day, but she isnt as tough as I am ... lol ... I also rode the sled here at home about a 20 mile trip, in the open fields and on a path along a ditch bank, and feel the sled rides almost as good as the Cougar does. So for now, I will leave the skid adjusted as it is as I'm not sure if I can make it any better.

OK, I am hoping this is the final episode for this thread. What I did tonight was I adjusted the RRSS to medium, and then low to see if I could get the suspension to travel farther down without stopping because the track would tighten and not allow it to go but maybe half way down. Both settings helped a little, but I still wasnt happy. So I decided to move the RRSS to the second hole further back, and put it on high. I was now able to get the suspension to travel almost all the way (about 2.5" from the bumper stop) with 200 lbs on the seat and my 185 lbs on the back bumper. I also loosened the track tension some, and then tightened the limiter straps to get all the slack out when the sled is sitting on the ground with only its own weight and sagging under its own weight. I did this so when I catch some air and the skid falls down as far as the limiters allow, the less it falls, the less the track loosens up. but it will not limit the skid travel for suspension sake. AS far as track tension, I adjusted it where theres about 3/16" sag in the middle under its own weight, and a little over an inch with the 10 lbs of pressure pushing down on it. So with the adjustments I did, I now have 6.5" of travel from the sled sitting on the ground after I have lifted the back end up and it sitting there under its own weight, to 200lbs on the seat and my 185lbs on the back bumper and bounced it down as much as I could. Measurements were taken from the mud flap to the ground.
DOes anyone know of anything I shouldnt of done? Or problems I will have because of what I have done?

My XCR track tention would tighten up a bit at full compression and I ran it loose on the stand. Your v-max is a short travel sled correct? The extra-10 sleds had 10" up front and rear.

I'd guess someone drilled the rails where you have the rr blocks for transfer. I drilled them in mine but didn't trail ride with them there. Short siccor travel = early coupling/trail perfomance, long travel = transfer but where you'd want it with the short front travel will be trial and error.

Did you use the donor sled measurements from the driveshaft and account for tunnel depth? Is that why you use the drop brackets? Curious.

I'd shoot for a lot of sag (0 front shock preload with YOU on it or even neg preload) and fresh shocks. Just tight front straps with you off it.

Just guessing.
