Conveniently located behind the left passenger peg, the RAP system allows for easy tuning of the shocks to account for changing loads or the addition of a passenger.

Questions & Answers

  • Hello i accidentally ordered the heavy duty shocks instead of the standard style, i weight 185 and my wife about the same. should i have purchased the Standard or are the heavy Duty shocks okay?

    By: Loyd

    It really depends on how much two-up riding it is that you do. Generally speaking, if you ride two-up and/or with a full load of luggage more than 50% of the time, then yes - the heavy-duty shocks would be ideal for your needs. Otherwise, your set up is going to be over-sprung. It'll certainly ride better than OEM, but as with all suspension matters, a properly sprung bike makes a huge difference.

  • do you have black?

    By: Guest

    Progressive's 422 series shocks are only available with a chrome finish.

  • does one or both shocks adjust? Pic only shows one cable or hose connected to one shock

    How does that work connected to only one shock?

    By: Toyz

    The Remote Adjustable Preload (RAP) function is there to fine-tune ride height once you've got your baseline ride height properly set. With careful tuning, you can get the shocks set up so that, depending on whether or not you're riding with a passenger - you can simply turn the RAP's knob a few times to get the proper ride height. You can do this since the shock that doesn't have the remote adjuster attached can also be adjust for preload using the included preload adjustment tool. In the instance you're unable to get proper ride height with the RAP alone during initial setup, then you will need to use the preload wrench to get it in range.

    For reference, it's actually not unusual to find modern suspension components with a preload adjustment on one side only. For those bikes, you often need to change out the springs in order to get the proper ride height. This goes for forks as well. While it's not as common on cruisers, over the last four or five years, it's become increasingly common on sportbikes and offroad bikes, both - MX and enduro machines. What's nice about the Progressive 422 shocks is that, since the non-remote adjustable side can also be adjusted for preload, you don't need to change out springs in order to get the right ride height.

  • I'm 6'6" and 350lb I do ride 2up allot is this shock right for me or is there something else?

    By: DR Death

    Heavy Duty spring rate would be the best option to suit your weight in the 422 series Shocks to fit a Harley Davidson Softail model. Heavy Duty spring rate is recommended for anyone that rides 2-up more than 50% of the time or has a combined rider weight with gear that is over 250 lbs. I would also suggest looking at a set of heavy duty fork springs for the front forks as well. This will give you the best ride quality matching both front and rear suspension together.

  • Does it matter which side you put adjusting side with remote control

    Does it matter which side you put adjusting side with remote control also my weight is around 210lb

    By: Mark

    The side on which the preload adjust varies based on the model year machine on which you're fitting the shocks. In the case of 2000+ models, the preload adjust is to be fitted on the left side of the bike. On old machines, Progressive instructs you to install the adjuster on the right side of the bike.

    As for the spring rate recommendation, if you ride solo at least 50% of the time, go with the standard rate springs. If you ride two-up and/or with a full load of luggage at least 50% of the time, heavy-duty shocks are what's recommended for your situation.

  • Do these raise the bike up?

    I am 6'5" weigh 230. I only ride solo on my softail springer. The previous owner was short. Will these shocks raise the bike up?

    By: Monster Williams

    If the shocks on your machine are stock, and you're riding an 1989-1999 Softail, the shocks measure 12.23" long at full extension. If you're riding a 2000-2017 Softail, the shocks measure 10.65" long. You'll be able to take two inches out of that should you want to lower the rear end of the bike.

  • what type spring do I need standard or heavy duty

    By: Johnny

    Choosing the right spring rate will make a big difference in how your bike responds to a Progressive suspension upgrade. 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, heavy-duty shocks are also recommended. Otherwise, standard-rate springs will do the trick.
