## Description

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.

Review: Great Springs - I will agree with a lot of reviews. These springs are a FANTASTIC upgrade from the stock setup. When you pull your stock springs and compare with the progressive springs, you'll be impressed by the difference. These are great for several reasons: 1. Budget. They're not expensive. They deliver a LOT of bang for buck. 2. Instructions are clear and well written. 3. The ride quality is NIGHT and DAY. They soak up the road better, keep your front end up in a corner and in hard braking. Take your time getting used to the feel, because it will feel different to your hands in the beginning. Worth mentioning, as I was unsure when I purchased: these are the standard duty springs. Progressive also sells a heavy duty set. I heard some saying if you're 200+ pound rider, go heavy duty. I'm 235. I'm glad I went with standard duty springs. They're plush with plenty of stiffness. I've tried hard to bottom them out. Haven't been able to yet. Progressive recommends installing HD springs if you ride two up often (I.E. close to that GVWR for the bike). I purchased both sets as I could not decide. The HD springs definitely look beefier. Bottom line: is this a race setup? Probably not. They're not gas charged cylinders. Will they excel at soaking up the trolley tracks on the Embarcadero on your way to the Golden Gate? Hell yeah.
Review: new shocks and fork springs, one mans opinion - just a few days ago i installed 412 Series Cruise Shocks in my 2006 1200c, i was impressed. i wanted to see if these fork springs would improve the ride/handling. bear in mind that sportsters have a suspension right out of the mid 70s and weigh in at about 540 lbs and are top heavy.... i live in the mountains of western nc many come here for the twisties and switchbacks. after about 300 miles on the new shocks and fork springs i went on one of my favorite rides about 60 miles of wonderful mountain roads, minimal traffic lots of curves takes about 90 min. not racing just enjoying the ride. night and day diff nope, the diff could be described as the bike wanting to go around the curves instead of making the bike go around the curves. a much improved fun factor, not once did i feel like it was the bike, rather my skill lvl that was the issue with some of the switchbacks. spent about $400 in shocks and springs, was it worth it. just depends on what you are after, if you realize that a sportster will never be a sport bike and want to have lots more fun then ya it is worth it ride quality improved, better dampening, smoother ride but maybe just new shocks as the old ones had 25k on them. for me it was a good choice

### ⭐⭐⭐⭐⭐ Much improved handling on a 2005 XL1200C with 20k miles
*by A***R on June 1, 2022*

When i ordered these my front suspension (stock) felt too soft and spongy. I have over 20k miles on the them and i figured it would be a good time for some maintenance. Upon draining my stock fork oil i noticed some discoloration. I disassembled the forks completely and cleaned all parts with brake cleaner. I replaced fork seals and all o rings. I decided to replace the springs and use a different brand oil with the stock dampener. This kit with Lucas 15w fork oil made a huge difference. The bike rides better than new. Drastically reduced brake dive and dramatically increased tire grip while braking. Highly recommended. My after thought is if this "budget" suspension made that big of a difference, what would a higher quality suspension do. Until i need to rework my suspension i am definitely more than satisfied with this.
