Rough ride but if you need bike lower it will do the job. It's a 1.5" drop specs but closer to 2".

quality shock not the top of the line(thats why the 4 stars) they are good for the average rider.i like the easy preload option.for the price it would be hard to find a better shock!

ap123@verizon.net

Very nice shocks, They said the shocks wouldnt fit my 2004 Sportster XL 1200C, but I ordered anyway and they fit perfectly. Very happy, big improvement over stock. Only thing when I adjusted the sag for just myself on the bike, it was at about an inch with the preload already at the middle setting? I don't know if that's good? Theres only one more notch left to go up, if I have a passenger. We'll see what happens then? I'll write another review at that time. All in all Big improvement over old stock shocks, good shocks for the money!

Great looking, fit, and functioning shock. It is what you would expect from Progressive and J&P and it delivers!

Nice upgrade to my old OEM shocks. Nothing drags anymore.

Important Product Notes

Note: When shocks are shorter than stock, clearance must be carefully checked for potentially dangerous interference.

Note: Standard Duty shocks are for ride loads under 225 lbs., Heavy Duty shocks are for ride loads regularly over 225 lbs.
