Worth the Upgrade
Thanks to Revzilla for another smooth purchase. You guys rock!

I wanted to write a quick review for anyone interested in upgrading their suspension. I ride a 2013 HD Softail. Looked at the 422 with the RAP, but settled on these instead due to cost. I also ride solo without weight, so I opted for the Standard version over the Heavy Duty. I'm around 175 lbs. Called Progressive just to verify and they recommended these. I also purchased the front monotube 2502 kit to complete the package.

Right out of the box after installing without any adjustment they're pretty stiff. I'm thinking all the way over counter clockwise is where you need to be if you always carry a passenger. Three turns clockwise the ride became more responsive and less jarring. My back appreciates that.

Overall impressions are good. It is a little expensive upfront, but pays dividends down the road. Handling is responsive, but not squishy. After looking at the primitive spring set up in my OEM front end suspension I was rather shocked. It's like a cheap slinky. Far less nose dive now. Feedback more confident. I kind of feel like the OEM suspension is far more generic. These make you feel less like a bicycle and more like an actual motorized machine if you catch my drift. We all know Harley slaps on the most basic components on their bikes.

It's a definite improvement. I would definitely recommend upgrading your suspension. It's worth it. And also this set up allows you to adjust ride height by 2 inches. Even though I'm already pretty low, it may improve the aesthetics of the rear. Tweaking these is a little tricky. You just have to find the sweet spot. I'm taking off a star because I think at this price it should come with the RAP adjustment. Overall I think this is a good investment.

Hope this helps in your decision.
