Your cart is empty.The original progressive rate fork springs soak up the small road bumps, yet are firm enough to absorb the molar-rattling ones. Spring rates have been chosen to reduce front end inch dive inch during braking, yet still provide excellent ride comfort. Better yet, we warranty our fork springs for life. Progressive rate fork springs have several advantages over straight rate springs. A progressive rate spring has the advantage of a rising rate resistance to compression. The benefit of this is that the spring can be soft enough at the start of the travel to offer a inch plush inch ride, yet be firm enough at the end of the travel to soak up the big bumps.

Easy install. Had to use my old preload spacers. Cut to recommended length per instructions. Combined with 10w fork oil. I ride solo ,170lbs. Did not need the heavy duty option. Good value.

Stock Harley springs are short and wimpy. It's as if they expect you to upgrade them. These aren't my first set of progressives, paired with a heavier weight fork oil (I run 20wt) it transforms the dampening and dive character of the bike drastically. This kit has the preload spacers already there and includes instructions.

Made sure to cross reference the part number being sold with progressives website to ensure correct figment. Got the springs and they are way too small. Look to be for sportster 39mm front end. Checked the part number and it does not match the part described. I’m sure an error was just made and they shipped the wrong ones but relatively frustrating since I had plans to put them in today. Will be reaching out to the seller to have this corrected and will update once I hear back.Update: they weren’t able to just send me the correct ones. I decided to just send them back and order them from Dennis Kirk instead.As far as the product goes- I am sure I will love them as I have progressive rear suspension as well. My 1 star does not pertain to the product but my purchasing experience form this seller.

Bought these Progressive Suspension, Standard, for a 2017 Breakout and they do make a difference.A lot longer that stock springs so you won't that much spacer.If you are somewhat comfortable with wrenching this is not a difficult swap.Just make sure you plan your work and have a list of torque specs for the bolts. This is your frontend, and you don't want it to come loose.Other than following the installation instructions I changed fork oil to 10W Bel-Ray at the same time. I think 5 W is HD standard in these.Result is a stiffer frontend. Now I'm happy I got the standard and not the heavy duty springs.And with the 10W fork oil and meassured up to the upper limit (15 cm below fork top) they are just on the upper stiffness limit I would like.Still haven't done any longer cruising, just test riding.But you can really tell that the bike is lot more firm on the road. In a good way.I my experience all american vehicles have way too soft shock absorbers. So this was money well spent.Notes for the job for a 2017 Breakout.- Front brake. 10 mm 12 p socket.- Front wheel. Remember to check how spacers and ABS comes loose. You'd typically want them back the same way.- Loosen upper fork "grip" ?? But not the lover as you'd want to loosen the fork caps first.- Loosen fork cap. 35 mm socket. Keep a small towel or something over the cap so it wont fly up your forehead. Remember there is a spring pushing it out.- Loosen lover fork "grip"- Get fork out. Clean them first and take it easy, you don't want to scratch them.- Oil out, pump them enough to make sure it's all out.- Cut spacer and fill oil according to instructions from manufacturer.- Put it all back together, be sure to follow specs.

WOW, what a difference. Took my 2014 HD Breakout from a kidney-jarring city bike to one I would feel comfortable cruising for hundreds of miles. Probably one of the single best upgrades I've done to my bike so far. You can tell the shocks have a progressive spring rate-- soft and comfortable yet stiff enough under the turns to make the bike rock-solid.

Head and shoulders above stock H-D fork springs. The springs are about 50% longer than stock and use a shorter space. The result is better tracking over bumps, much less fork dive when applying front brakes, and better handling overall.Installation is simple and the directions are pretty clear. Just be sure to use a towel to cushion the blow when slowly and carefully loosening the fork cap. I forgot the towel and ended up with a gash on my hand when the stock metal spacer jumped out of the tube. After removing the metal spacer, but before removing the springs, use a yardstick or ruler to measure the fluid level in the fork tubes and note how far from the top when the forks are fully extended. Drain the oil because it's probably old and not performing as it should be, and because new fork oil is cheap. Use either H-D regular weight fork oil (which isn't clearly labeled with weight) or the lightest weight fluid (likely 5w) at your local motorcycle shop, as a starting point. When you put the new springs in, fill to the same level as with the old springs. On my Dyna, it was about 24 ounces each side. The difference in handling will be dramatic by changing just the springs. If you wish to stiffen up the forks and increase dampening more, you can go to the next weight of fork oil.
