Progressive Suspension 422-4037C Chrome Adjustable Rear Suspension Shock

These were installed on a 2013 Harley-Davidson Softail Heritage Classic (FLSTC). This item would not fit my motorcycle, according to the Amazon "garage. " The description of the "garage" was incorrect. TL; TL; TL; TL; TL; TL; TL; TL; TL; TL; TL; TL; TL; TL DR – These are a huge step forward from the stock shocks. Considering the softail's limited rear suspension travel, these do an excellent job of smoothing out small bumps and absorbing the sharp jarring of larger ones. I would do it again now that I know what I know. Those in doubt should go to the manufacturer's website and look for fitment for their vehicle, then return to Amazon and look for the manufacturer's part number. Take the part number at face value. Perhaps trust the image (the image for the 422) that was provided. (For the record, 4037C is the right answer. ) When the Amazon garage says the part recommended on the manufacturer's website won't fit your bike, don't necessarily believe it. br>br>Getting the bike off the ground: Some sources claim that these can be installed with the rear wheel off the ground and the bike supported by the jiffy stand, front wheel, and a jack under the right side of the frame. I couldn't get that to work, and I was afraid to try too hard because it just seemed to put the three contact points with the ground in too much of a straight line. I tried using my motorcycle lift (but to lift the motorcycle, I had to put the lift supports right across the stock shocks, which meant I couldn't remove the shocks). I ended up putting the bike on jack stands in front of the swing-set, which was supported by a 4x4. arm and front wheel on a floor jack (the bike was, of course, strapped to the width of the 4x4, limiting the amount of wiggle). br>br>Removing the OEM shocks was not difficult. br>br>Instructions for installation: 1) Loosen the preset nut before installing – this will make setting the preset a lot easier. br> 2) Tighten the forward mounting nuts after installing the rear mounting bolts. br> 3) The supplied preset adjustment wrench is a little wiggly on a ratchet. Instead, I used a 3/8" drive breaker bar, which I taped down to make it less wiggly. 4) The shock's height adjustment does not appear to allow the bike to be raised above its stock height. There are a few 2. Allows for a 5" reduction in height. br>br>According to the documentation/instructions that come with the shocks, the preset is set to the minimum (softest) setting when they leave the factory. I'm about 200 pounds and found that firming up the preset by a factor of 1. For me, 5 turns (on both shocks) is on the stiffer side of right. I'm still trying to figure out if this is the best setting for two-wheeling. up with the spouse.

I'm running these on an '09 Fatboy and they're a huge step up from the stock shocks. I also installed progressive cartridge inserts in the front forks (which I HIGHLY RECOMMEND) and they completely transformed the bike: "They make the whole bike feel smoother and much more "planted," to quote from my other review (front forks). " Corners are more predictable and stable, the ride is smoother, the bike feels more coordinated, and the overall impression is of increased confidence. "br>br>I've put a lot of time and effort into this bike, but before you focus on performance and aesthetics, consider these shocks and cartridge inserts for the front end (which are actually less expensive).

If I'm capable of doing it. br>Anyone with basic mechanical skills and tools should be able to put it together. I recommend that novices like myself watch videos and study the parts list. br>I replaced both the front and rear tires at the same time. br>The bike had been lowered when I bought it, so this was done to get it back to its original height. br>Just the difference in height is enough to alter the ride. br>I don't do a lot of riding around, so I can't say how much of a difference it made, but I can say that I no longer have to ride around the speed bumps in my neighborhood. I just glide over them as if they didn't exist at all. br>I definitely felt a better ride, so for the price and ease of installation, I recommend progressive shocks.

There are many reviews on softails for 422s, but I'll do my own review on Amazon. com. br>br>Amazon does not sell this item. com, but the seller was fantastic and arranged for it to be dropped shipped to me. So kudos to him for that, as well as his excellent communication skills. Now for the surprises. br>br> Stock shocks with the lowering bolts were installed on my softail deuce. It was probably reduced by a factor of two. 5" from our current inventory I'm 30 years old and healthy, but the hard bumps and bottoming out were killing my lower back. br>br>I used these shocks and initially lowered it by a factor of 1. Preload was set to factory (nearest softest setting) and the length was 75" from stock. I went on a cruise and it was far superior to the stock version. Because I didn't have a lot of travel before hitting the bumpstops, it was better but not perfect. As a result, I increased it to around 1. 5"- 6 lbs. less than stock, with a slightly softer preload. Now I like the ride, the height, and the overall appearance. Because I'm around 160 pounds, I wanted a lighter preload than most people; they recommend 3/4" sag when sitting on the bike vs. 1" sag when standing. not. I'm not getting 3/4", but more like 1/2". However, due to the weight of the bike, it sags about 1/4" on its own. It sagged even more after I put my 190-pound brother on it. br>br>Installation was straightforward, but without the proper tools, removing the nuts on the rear shocks will be difficult. The solution was to use a 3/4 open wrench and a hammer.

What a difference these made on my wife's Ridley automatic motorcycle. The bike now rides like a new bike, whereas the old shocks made it feel like you were riding a log wagon. I tried everything with the old shocks with only 750 miles on the bike, but eventually gave up and got these new ones, which I am glad I did. It was simple to set up, and I immediately noticed a difference.

FXSTD. Even though this website said it wouldn't work for my application, it worked perfectly. Before making a final purchase, I did some research and found that they were a perfect fit. Also, the rear was lowered nearly two inches, which improved turn stability and bump handling, particularly in a hard turn. I would say that these are a far superior product to the stock application!.

When I put these shocks in, two amazing things happened. For starters, I was able to obtain what I was primarily looking for. the lowering of my Heritage by an inch or more (I could go even lower, but there's no need). However, after installing these shocks, I discovered an unexpected benefit. My bike is more maneuverable than it has ever been. I'm a fast rider, so the improved handling with these shocks was well worth the money. Progressive makes a fantastic product, and this was the best thing I ever did for my bike.
