For machines that are equipped with two shocks, they are indeed sold in pairs.
Yes, Progressive 412 Series Shocks are sold in pairs for machines that come the factory with two rear shocks.
If it's the bushings that go between the upper and lower shock mounts on your machine, then yes, they're indeed included. In fact, depending on what bike you're mounting the shock(s) onto, the kit may include a myriad of bushings to fit since one set of shocks may fit more than one machine.
Travel varies, depending on which shock length you select to install on your bike. In the case of the 2006 FLHX street glide shocks, the length of travel for each shocks is as follows:
1.85" for the 11.5" shocks
2.35" for the 12" shocks
2.85" for the 12.5" shocks
3.48" for the 13" shocks
3.98" for the 13.5" shocks
As you can see, the greater the shock's length, the more travel that's available for your bike. And don't forget to choose the correct spring rate to fit your particular riding needs. With Progressive's 412 shocks, heavy-duty springs are best suited for solo riders over 220lbs. If you ride two-up and/or with a full load of luggage at least 50% of the time, you'll certainly want to go with the heavy-duty springs to cover that extra weight.
Yes, according to the data I have from Progressive, the 2001 model year Road King Classic shipped from the factory with 13" length shocks, so you'd certainly want to order shocks from that are of the same length to avoid having to fool around with suspension geometry. Another important factor to consider is your weight, and whether or not you plan to travel heavy (two-up and/or with a full load of luggage). If you're over 220 lbs, and/or travel two-up/heavy at least 50% of the time, you'll want to choose the heavy-duty spring rate. Otherwise, the standard rate shocks will do an excellent job.

Progressive recommends that heavy-duty springs are to be used for solo riders over 220 lbs. Furthermore, if you ride two-up and/or with a full load of luggage at least 50% of the time, heavy-duty shocks are also recommended. Since you're two-up 40% of the time, you should certainly consider the additional weight of the batwing, saddlebags and the trunk you want to add later on. Just add those items to your own weight and, if that puts you at 220 lbs. or more, then you'd certainly be wise to go with a heavy-duty spring rate.
Furthermore, we strongly recommend the installation of a matching set of fork springs to go with any Progressive Shocks. Should you choose the standard-rate rear shocks, then the standard rate Progressive Fork Springs will do the job nicely. If you go for the heavy-duty spring shocks, we recommend Progressive Heavy-Duty Fork Springs. In doing so, you'll be sure to balance the front and rear spring rates equally, which in turn, minimizes the back-and-forth wallow that's common anytime front or rear spring rates are mismatched. This becomes more noticeable the faster you go and with bigger bumps.
Yes, you can indeed use Progressive 412 shocks without air since. The shocks themselves actually have no provision for air, so there's no need to worry about hooking them up to that system.
The standard 1993 XLH883 comes with 13-1/2" shocks from the factory, so you'd actually be reducing the amount of travel available if you were to select the 12-1/2" long shocks. In addition, you would be changing the bike's steering geometry since you'd be lowering the rear end of the bike.
While more suspension travel is nice, the best thing you can do is order springs that are of the correct rate for your weight and riding needs. That is to say, it's not the shock's length that effects travel as much as spring rate does. A properly sprung bike will rarely bottom out. If you spend most of your time riding solo and weigh less than 220 lbs - then a standard rate shock will do the job. If you travel two-up and/or with a full load of luggage on the bike at least fifty percent of the time, you'll want to order a set of heavy-rate springs.
If changing the bike's geometry is of a concern, then you should order a set of 13-1/2" shocks so as not to make the bike handle differently. Again, the most important factor for resisting bottomg is to choose the correct spring rate for your needs. With that, regardless of the spring rate you choose, you'll find the bike will not bottom out.
The 2000 model year Harley-Davidson FXD shipped from the factory with shocks that measured 12.6" eye-to-eye.
There are two things that you can do to get the best possible ride for your needs. The first is getting the correct spring rate for your weight and riding needs. Heavy-duty rate springs are advised for solo riders that weight more 220lbs. Furthermore, if you ride two-up and/or with a full load of luggage at least 50% of the time, be sure to choose heavy-duty springs as well. Just about all of Progressive's shocks, including the 412 Series Shocks, are available in standard and heavy-duty spring rates.
The second important factor, and this is especially true if you decide to go with heavy-duty shocks - is to match the fork springs to the shock. In this way, you're assured that both ends of the bike will react the same to irregularities in the road since progressive-rate springs act differently than the OEM straight-rate springs in the forks. In this way, the bike will wallow less over bumps and you'll notice it tends to track very true when hauling it around corners. Of course, the faster you go, the more noticeable these differences will be come.
The difference between straight-rate and progressive-rate springs is that, with the former - no matter how much you compress the spring, the amount of force it exerts remains nearly the same. Progressive-rate springs, on the other hand, exert more force the more they're compressed. In other words, the bigger the bump, the better job the progressive springs do in quickly slowing those forces without the heavy jolt you'd feel with straight rate springs over the same bump.
Be sure to choose the correct Progressive Standard Weight Fork Springs or Progressive Heavy-Duty Fork Springs from our website if you want to get the best ride possible.
And, I did fail to mention - there's one solid rule about suspension that applies anytime you're comparing the stock item to an aftermarket part. That rule is that that you don't know what good suspension is until you've tried it. You will find that Progressive shocks are a significant improvement over the stock items, no matter where you ride or how you ride. And if you're looking for the best possible ride, we implore you to match the shocks with a set of Progressive fork springs as well.
will this 412 work and can I get it in all black. I am pretty sure the studs are 5/8th of an inch. Please give the the exact item # so i can order these. Thanks in Advance Bill
Yes, the 412 shocks will indeed fit your 1969 Harley Sportster. Considering your weight and the fact that you'll be riding solo, the standard rate shocks will do the trick for you. Each set of Progressive 1969 Sportster shocks come with the appropriate bushings to fit your bike, so there's no need to order any additional parts. With regard to an all-black set up, unfortunately, the only shocks we have to fit your machine are available in chrome only.

The 2010 Harley Sporstster XL1200C shipped from the Kansas factory with 11-1/2" long shocks on it. Mind you, aside from XL1200C shock length, be sure to choose the correct spring rate for your needs. If you're a solo rider at least 50% of the time and 220lbs or less, go with the standard rate shocks. If you're bigger than that, or ride with a passenger quite often, you'll want to get a set of Progressive Sportster shocks with heavy-duty springs.
is the top to wide for the bike or doesn't stick out far enough from the fender strut?
By: Brent R
Progressive's 412 shocks will indeed fit the FXDS Dyna Convertible. The tops won't be too wide to fit, either. We've sold quite a few of these to fit that particular bike and I'm not aware of any interference issues between the fender strut and the shocks. Nor has there been a problem with the shocks being too wide to fit. Everything you need to complete the installation is included in the box.
There's no need to purchase any spanner wrench in order to adjust any of the Progressive shocks that we sell! They all come with one in the box that'll allow you to make the required adjustments. The included shock spanner wrench is specially shaped to fit the shocks you purchase which makes tuning it a snap!
The OEM shocks for the 1999 Kawasaki Vulcan 1500 Nomad measure 13" eye-to-eye. Choosing any shock that's shorter would, obviously, lower your bike. With regard to have the bike still right, you should seriously also consider Progressive Fork Lowering Kit as well. In doing so, you retain the bike's stock steering geometry and the way the bike handles would not change at all. We always recommend that, whenever you lower the rear, you also lowers the front of the bike as well. Progressive's Fork Lowering Kit has everything you need to adjust for this in that kit.
I am about 5'8" and weigh 230 pounds. Would this shock be right for me? If not what would you recommend?
In the case of the 2013 S40 Suzuki's stock suspension, you'll find that these shocks are s significant improvement over what came with the bike. Based upon the information you've provided, you'd want to get the shocks with heavy-duty springs.You'll find the bike rides a whole lot better with the heavy-duty shocks installed.
The 1983 FLHTC came with 13" long shocks from the factory.
I want to order a set of these shocks but not sure what size I need. Would like to go a little lower than stock...
The 2006 model year Harley FLHRC Road King Custom shipped from the factory with shocks that measure 13" at full length. Also, regardless of the shock length you choose, be sure to choose the correct spring rate for your riding needs. If you ride two-up at least 50% of the time, and/or with a full load of luggage, you will want to opt for heavy-duty shocks. This also holds true if you weigh over 220lbs. If those conditions don't apply to your needs, then the standard-rate shocks will more than be up to the task.
So long as you weigh less than 220lbs, the standard rate shocks from either, the 412 or 430 series will be ideal for your needs. If you weigh more than that, go for the heavy-duty shocks.
As for the differences between the 412 and 430 Street Glide Special shocks, the main difference between them, other than appearance, is the internal valving and the way you adjust spring preload. On the 412 shocks, you need to use the included shock spanner wrench to adjust preload. The 430 series shocks can have their preload adjusted by hand, which makes setting proper static sag very easy. The valving differences are quite significant. 430 shocks use a floating piston to separate the shock fluid from the pressurized gas chamber. In doing so, damping action is improved over the 412 shocks. And that's not to say the 412s are bad - they're great, especially when compared to stock. 412 shocks use a standard working piston instead of the floating design.
No matter what you choose, and especially since you've updated the fork springs, you'll find that the bike handles a lot better than it did in stock configuration. It'll track true through the
The 2008 XL1200N shipped from the factory with shocks that are 11" long.
I plan on a heavy duty application cuz me and the woman are thickish. I've never liked air shock handling & they bottom out a lot. Recommendations???
The 2003 Road King Classic shipped with shocks measuring 13" long, but you can select shocks in any length that we have available to fit your machine without the worry of bottoming so long as you select the proper spring rate. If you're over 220lbs solo, and/or plan on riding two-up at least 50% of the time, you'll want to go with heavy-duty shocks. And, unless you want to lower your bike to make it easier to reach the ground when stopped, we recommend that you stay with the original shock length of 13". In this way, the bike's steering geometry will remain unchanged.
One thing you'll want to strongly consider as well, in order to keep the bike balanced, is to replace the fork springs as well. With the front and rear end of the bike tuned the same, wallowing and bouncing about won't be a problem. We have a Progressive Heavy Duty Fork Spring Kit that'll take care of that without issue.
So long as you were to go with heavy-duty rear shocks in stock length and HD fork springs, your risk of bottoming will be minimized. Compared to air shocks, the 412 series doesn't get harsh as you push through its stroke - they get firm, yes - but it's a nice, progressive push with no big hit near the end.
