2020 Yamaha Sidewinder SRX IQS to QS3-R conversion.

Honestly the IQS is a joke. The center shock is garbage and the others are progressive springs with basic qs3.

good when the trail is smooth lol

Looks like I have something new to do this offseason. I'll be looking to do the same and sending out to @cannondale27 when I get all new shocks and springs in. Thanks for sharing this build!

Thanks @cannondale27 for the quick service on the QS3R with iQS with the Elka Dual Rate Springs for my '25 XTX LE 146". Can't wait to use these this upcoming winter. Now I just need to figure out if there is an option for QS3R's for the Rear Shock on the 146".

Thanks @MrSled for sharing this mod with the group. QS3R with iQS is the best of both worlds.

I am jealous of this set up. I need to find a set of QS3r's for my new Riot 9000

Awesome thank you!

Your welcome!! It’s an awesome upgrade.

Tell us more about the spring set up. How did you come up this combo? Were there any other options or considerations?

I put on the springs from the 2024 cat RR on the front and set them with sled hanging until jamb nut just touches plus one turn. Center chock used stingray spring and set preload the same and due to my weight of 255 lbs added 4 position cams and run them on the highest setting.

FYI, I have sold the old shocks.
