Husqvarna
A Class
Gateway Husqvarna called me up on Wednesday - told me my "Variable Preload" collar from the Husqvarna special parts catalog had arrived. I installed it yesterday and took a few pictures.
Here's a blog post with a few more pictures and some observations from the install. I was surprised to find that a spring compressor was needed for the 449 shock - all other off road bikes I've worked on have enough length on the shock body to remove the clevis by undoing the preload adjusters all the way. Also, the stock lock ring adjusters are small enough that you can remove and install the shock without shifting the subframe - the performance part is not. I had to remove the top subframe bolts and tilt the subframe/gas tank backwards in order to reinstall the shock. Not a big deal, but a discrepancy from the service manual that needs to be remembered.
The adjuster is very nice, and will make trackside sag changes a breeze.
