Sagging 05 900 IQ 166

[SixtySevenGT]

My Rear suspension has a bit of a sag to it. When I lift up on the rear bumper it will come up about 6 inches more.

Could this be a low charge in the shock ?

Rear springs are on High setting.

I've had this same problem, first time it was a bad rear shock, had it rebuilt and then I also changed out the rear torsion springs to the .407 heavy springs, which helped alot. I am also a bigger guy too. So could be eithier I guess. You could pull the rear shock out and compress it and see if it rebounds or not.

Shock Test

OK I'll try the shock. I need to measure the springs see what it has.

This is my first season on this sled. I rode it one already I was impressed.

The shock has no effect on suspension sag...it's just for dampening. There will always be a bit of sag in the rear suspension. Holz recommends 3-1/2" of sag as measured at the rear of the seat on their coilover suspension...not sure what factory Poo is. Try some larger diameter springs if the sag is too much for you

Just finished putting in the 225 front track shock spring, and the 375 torsion springs on my 900.
On the garage floor loaded right up with fuel and such,sits high and proud finally! I think almost all IQ`s out there have an issue with sag on the stock springs. Mine was fine for the first year then it just kept getting lower and lower

i agree for the average weight rider up to 225 the .375 springs are a must. over 225 the 407's are the ticket. we have done this to several 9's they ride better and sit higher

Where the best place to get the 407 springs? and does it make it ride stiff?

http://www.babbittsonline.com/pages/parts/viewbybrand/14/default.aspx is where i get my stuff. my bro tried the 407's and he is 180 and they where a little stiff for him, we took them off and put the 375's on and it was much better. the 407's will be better for heavier riders

Ok thanks ,that's what I wanted to know ,I weight about 200

 

[SixtySevenGT]

thanks guys

I will do the 407 s and the SLP adjuster block. I believe the shocks are fine.

OK-Am I blind or what.
I just looked at babbits- I am looking at # 19 torque spring- I don't see a 407 or the 375- Help.

Biggdawg- What are you going to do with your 407's?

 

[Danbot]

First ride today with the 225 track shock spring and the 375 torsions and its noticeably stiffer... no more sag. I weigh 220 or so dressed to ride and its seems alot more ideal for me now.

407 mistery springs / where

Talked to Carls today they never heard of the 407

They sell the 375's by the gross.

So Iam in the same boat, if anyone has a set of 407 let me know.

They are .405's...the .375's are stock for a touring sled so they are easy to come by.

Here's a link for the .405's

Might as well open all the windows too while you're at it...it'll make adding anti-ratchets that much easier if you ever decide to.
