junk shocks on 08 xp 163

i've went to two differnt dealers now with my 08 xp 163 about shock issues with the rear skid they wont do a damn thing to replace them. with about 40lbs of weight to the rear of the tunnel the suspension will bottom out and stay down it wont even try to come up no rebound. but if you lift the rear bumper it will stay up. one dealer said the summits are supposed to be like that for sidehilling. well what about the rest of the riding its f'in bottomed out!
if anyone else had an issue with this, or what your dealer did for you it would be great to hear back. errrrrrr!
 
on second shock now and still the same thing. always sacked out and track is tore to hell. no answer from dealer
 
Some of the shocks didnt come with enough nitrogen in them on the 2008s. Maybe have someone make sure there is 300lbs in all four shocks. There is a stiffer rear spring available too that would help. I have front set of 2009 summitx t/a shocks and springs for sale if you know anyone interested.
 
Something to remember. Springs hold up the sled and the shock and or damper controls the energy that is put into the spring. (ie) the energy of hitting a bump and controling the rebound that the spring returns after hitting the bump. But hey opinions very.

Very good point. To prove this you can take the rear shock out of the skid and compress it by hand. You will notice the shock barely rebounds and moves very very slow. The shock has little to do with holding up the weight of sled and rider. Try to talk your dealer into the heavier springs. They are not that expensive.
 
SAme troubles here. Gave up and traded on a Polaris. Too many shocks, hand warmers,belts, engine cranks.
 
There is a stiffer set available through ski-doo now. Sorry but I dont have the part numbers.
 
I was talking to my dealer about this as well, he thinks the geometry is also slightly wrong on the suspension and this adds to the problem. My sled didn't sag that bad but I put washers in between the drop brackets on each side and now it comes all the way to the top. I am not sure what this does, but it seemed to help.

I explained that after 20 years of riding and racing motocross turning suspensions was something I was very familiar with. Suspensions are fairly strait forward there is compression, dampening, spring presser and REBOUND!!!! Then I was told to check the bolts that linked the system together and make sure they weren't to tight and binding the linkage. They weren't... So if the springs are set to the stiffest setting the limiter strap is 3/4 out and there is no other obvious problems, when I sit on my tunnel it should REBOUND!!! It didn't, it just sat on the track. The spring should push the tunnel back up however i think the shock had some valving problems and would hydraulically lock up when fully compressed and wouldn't release or rebound. So I said just order the flipped shock and if I'm wrong I'll pay for it out of my own pocket. After waiting all winter it showed up, so I pulled my sled out of storage took it in and sure enough BAD SHOCK!! They fixed it under warranty no problem. Tell your dealer to order you a new one then when it comes in, take them your old one and they can compare the two. If they wont do that for you tell them you know a dealer that will and that's where you will be heading when it comes time for a new sled!!!!!

hotboat is right , this is excatly the problem, the vavling is shot, the heavyier springs people are installing is just compensating for the weak shock. dealer recharged first shock, still no good. installed new shock and it lasted about a week. after it sits in the garage for a day the rear suspension is very stiff with stock springs, but once you work the shock a bit it just sacks out and stays there. hope brp comes up with a answer so i dont have to fork out the money for a float.

the geometry sounds like it is also off a little which is helping the shock
