Hi, when my dealership installed the Front Springs, I had handed them the little 2" long spacers that progressive had included, even though the online website mentioned using the original spacers. When they were done with my bike, my front end was actually about 3/4" higher, and remains with the higher ride height than it ever did when I first bought the bike, so I'm assuming they re-used the stock spacers. I also had them put in 15W oil instead of the stock weight (8W or 10W), and have been very pleased with the results. The front end has alot less dive under breaking, and the bike leans over alot more aggressively because the front end "sets" sooner. Great Mod!!
