These came off the factory Zip-Ty Husqvarna race bikes. They have limited use and come complete with spring. This is the ULTIMATE shock for your 449/511. This isn't a stock picture, it's what you'll get. If you've ever shopped for these you know they run $800+ new. We have 3 available and I'm offering them here first for our best customers who've supported us along the way. Mix some Swedish with your meatball! $400 - NOT AVAILABLE ON LINE! You must call the shop to get these. 760-244-7028
