 DK Custom Products has tested numerous aftermarket shocks over the last 8 months.  We've logged well over 15,000 miles on a variety of bikes and trikes, covering an array of road condtions, loads and speeds.   All this while paying close attention to ride quality with the various shocks.  

Additionally, we spent 2 days testing various shocks on a Shock Dynamometer, measuring compression, rebound, spring rates and travel. (see photo)

Unless you go to a custom reservoir type shock, (costing over $1000), we don't believe you can get a better ride than from the Pro-Action Street Series Shocks for your Harley-Davidson.


Custom Tuned to Your Bike & Your Riding Style/Loads



  • Top of the Line Pro-Action Shocks give superior ride quality.  Not only do they smooth out the bumps, large & small, it is amazing how much more stable your bike/trike will feel going thru the curves.  It is confidence inspiring.
  • The T6061 Billet aluminum bodies house a unique 3-stage progressive valving system for compression, and a 2 stage rebound system.  Coupled with "fit to you" coil over springs that have an adjustable pre-load, you will be amazed how much smoother and more stable your bike/trike will ride.
  • These Street Series Shocks are available in 3 lengths: 11.25", 12.25" & 13.25".  The travel is 2.5", 3" & 3.5" respectively.  Combined with less sag than the stock shocks, this gives an average of 33% - 50% MORE Travel. (Unless otherwise requested, we will send the OEM length shocks for your bike to you)
  • When you order you will be asked some easy questions.  Your answers give us the information needed to use the correct spring rate for your shocks, as well as giving us the info needed to adjust the pre-load and rebound for you.  This way when you receive the shocks they are already set-up for you.  Simply bolt them on and ride! 
  • You can Lower or Increase the Height of your Bike by requesting a different Length Shock.  We will send the stock height shocks for your bike, unless you request in the "Special Instructions", at checkout, 1" shorter or 1" taller Shocks.


Limited Life Time Warranty Details:

Only for the original purchaser of the shocks

Does not cover accidents, fire, environmental catastrophes (submerged in a flood, etc.) 

Does not cover if the shocks were abused (overloading them), improper installation

If they are installed properly, not overloaded, not damaged by some external force, then they are Lifetime shocks for the original purchaser....if they wear out, they will be rebuilt/replaced  at no charge.

" ...the 444's were 100% better than the OEM Air shocks and the Pro-Action Shocks are 100% better than the 444's.

I believe the biggest experience change would be anyone going from the OEM Air directly to the Pro-Action shocks." -Roger


"I had a huge improvement in both sport feel and cushion. The suspension was stiff enough to hold my lines well going in and out of the turns but soft enough to take the bumps that would normally make me sore or tired in the arms.

Thank you for all your help and great customer service. You have sold me as a lifelong customer and can't wait to get the front suspension redone through you guys."  -Giang Vu

Customer Reviews

I can't even tell you the level of improvement Review by DirtyOldMan
I previously had Works shocks specially made for my bike. They were a huge improvement over my stock shocks. Works went out of business and I needed mew bushing and no proper replacements were available. I made some but apparently not well enough.

I finally ordered the Pro-Actions from DK and installed them. I never realized how noisy and uncomfortable my shocks were. A world of difference so far. I haven’t done any real twisty road riding yet but am pretty sure my dollars went to the right product.

As far as customer service, Dwayne and company have it down. Thanks! (Posted on 2/1/2019)
Awesome shock's for the Fat Bob's!!! Review by Krazy
I went w/ the 13.25" length Pro-Action Street Series Shocks as I wanted more lean angle & to have a shock that could handle the bumps...
The 1st thing I noticed is how the shocks do absorb the bumps & now I don't avoid them like I used to!!!
The 2nd thing I noticed is how much easier the bike leans or falls right into the twisties now as I'm not havin to work the bike as hard like I used to!!!
The 3rd thing that I noticed is I'm takin the twisties at a faster speed than I used to & even my son said he doesn't have to slow down as much now when he's followin me on his sport bike!!!
The 4th I'm goin to do is I'm goin to get a set of Avon Cobra's as soon as I wear out the stock tires so that I can go even faster thru the twisties!!!
The 5th thing is Thank U Dawn for lettin me pick your brain & recommendin the Pro-Action Street Series Shocks to me & my back Thanks U to & Thanks to the DK Customs crew for for doin all the testin of the different shocks which made my decision even easier on what shocks to buy for my bike & save me money in the long run!!!
