So 06 intruders won't fit?

I went with Progressive Suspension's 412-4201C 11.5 inches (stock shocks are 10.5"). Ordered them from JC Motors.com. These were listed for the Suzuki Intruder 800. Perfect fit, easy installation. No other mods were necessary. I used the stock hardware, the proper fit bushings come with the shocks. The only possible issues were sidestand (bike lean) and passenger peg clearance with the stock muffler. With new shocks fully extended, passenger pegs clear by 1/2", just enough. The tail light comes up about 2", the seat about 1", and the sidestand about 1/2". I chose to compensate by attaching a 1/2" x 1" bar magnet to the bottom of the stand, just my choice, (also helps with stop light timers!) but not necessary. Good Luck, hope this helps!

P.S. The ride is soooo much smoother!
