A aftermarket can will always screw up the balance of the sled. The bandaid it to adjust the shock springs or air to compensate.

Reviving this thread, just weighed my summit sp, half tank of fuel, full oil, goggle bag, handlebar bag, cfr bars and 4" riser electric and manual start, MBRP trail can.

+/- 2 lbs

FLS 151lbs , FRS 171lbs and rear just under torsion springs 202lbs.

Curious to see the left hand side lighter than the right,.. since I have an MBRP trail can installed.

A aftermarket can will always screw up the balance of the sled. The bandaid it to adjust the shock springs or air to compensate.

Looks like in this case the stock can would just put it farther out of balance lol

That is possible, but more likely skidoo doent make any real effort to balance it perfectly from right to left with the muffler...

I thought that was the point of the G4, rider balanced or something? The purists on here say so. I would take 20 pounds lighter overall vs being concerned about a weight difference side to side. But thats just me.

Yeah not sure how balanced the G4 is?

I have never really gave it any thought, I'm sure it could help a little, but I think we are giving them too much credit to think they factor the muffler into the over all balance of the sled.

I could be wrong though.

Humm wonder why im running staggered preload settings. Yes this sled has a aftermarket can.

In 09 i first noticed this when setting up my fox shocks. Jack the front end up put in the recommended air and put the sled back on the concrete. There was more air pressure showing on the clutch side vs the exhaust side. Had to add more air to the clutch side to even out the ride height.

Ive been setting my sleds up like this ever since.

But I remember lund getting flamed for this practice so I don’t expect any different treatment on here. Lol

Clutch side ski shock


Exhaust side ski shock.

The loss in weight on the exhaust side causes the ride height to go out of wack.

This is even more evident when the sway bar is disconnected.

I never had that problem on mine, but the springs are a lot heavier on my shocks though.

It could be. My t3 is 17lbs heavier on the clutch side vs the exhaust. With my aftermarket can on. The other guys numbers I dunno. Lol

I actually ran this sled almost a whole season with the stock can on it. After adding the aftermarket can I noticed more negatives than positives. I doubt I’ll ever invest in a aftermarket can again.

I went back to the stock muffler too. Just because I like the sound better though. My loud can days are over lol

I just went and reweighed the front,.. the first numbers I posted were a little off by a few pounds. Anyways I just adjusted the LHS to ZERO preload SP shocks, the RHS I left at Max preload and reweighed,.. LHS 149lbs and the RHS 150lbs, so I think I am pretty good now,.. now 50lbs difference front to back,.. maybe decrease front track shock a little?

Yeah I recall the Lund discussion.


Now weighing it in the garage only measures static load. So under dynamic loads how do you compensate for that as the clutch side would create forces not constant or easy to measure.

Oh. And I don’t really care. I ride down the trail towards the fresh pow on my first ride and if one sides feels squishy I increase or decrease it to my liking and never touch it again.

In them hills.
Like I said the are a lot of adjustment with the torsion springs. They make different rate springs, there are now aftermarket spacers.
Ive done air shocks on a doo before. Never again.
That nextech fox float rear torsion spring delete was the best thing I ever did to an XM.

I imagine it would work wonders for a G4 too.

I’m going to put the spring spacers in my new freeride and pretend I know what I’m talking about! Soo many adjustments.... where do you start?

The skidoo race manual gives a good explanation on how to setup your suspension. Your sled won't have all the same adjustments as a race sled, but it goes into detail on all the ones you have to work with.

You definitely need to ride the machine and adjust based on rider preference and general feel of the machine. Depending on the shocks, you're not gonna see any big gains when you make the adjustments.
