What Are Harley Davidson Dyna Rear Shocks? 

Whether you are looking to adjust the height of the Dyna or you want a smoother ride, the right rear shocks are essential. With adjustable Dyna shocks, you can ensure less friction and more performance. The specially calibrated shocks allow for better rebound and compression. 

Plus, preloaded adjustments make it easy to either stiffen or soften the ride based on the terrain you are traveling on. You can also accommodate riders of different weights with a simple adjustment. With other motorcycles, it can be difficult to find adjustable shocks, but these high-quality options are expected with the Harley Davidson Dyna brand.  

Reasons Why Dyna Riders Adjust Their Rear Shocks 

The suspension is responsible for how the ride feels, especially when you are traveling over bumps. If you have the Dyna shocks adjusted properly, you aren’t going to feel all the bumps and imperfections as well. The handling is also improved because you aren’t being thrown around with the road.

Additionally, it’s important to adjust the shocks based on your height and weight, helping the fit to be just right. What might feel good for one rider could be completely uncomfortable to the next.

How To Adjust Dyna Rear Shocks (Step-By-Step Adjustment Guide) 

It’s important to know that adjusting shocks on your Dyna might be different based on what model you are riding and the type of shocks you use. If the suspension is bottoming out, you will want to read the owner’s manual to find the appropriate setup. However, we can provide you with some basic instructions.

    Remove the tool from under the seat.  
  2. 2
    Make sure the bike remains upright at all times. 
  3. 3
    Apply the tool to the top ring of the shock. Turn it counter-clockwise to loosen it.  
  4. 4
    Turn the lower ring clockwise to tighten it.  
  5. 5
    Continue moving the rings until you reach the appropriate amount of dots that are outlined for your load in the owner’s manual. Depending on how far you go, this process could take a little time.  
  6. 6
    Bring the top ring on the shock down to meet the bottom ring. 
  7. 7
    Tighten the lower ring counter-clockwise with the top ring.  
  8. 8
    Do the same process on the other side to match the shocks.

People Also Ask (FAQs)

How do I know if the rear shocks of my motorcycle are bad? 

When the rear shocks go bad, the ride becomes softer, especially as speeds increase. The rear end of the bike will also start to weave when traveling over bumps, and traction can suffer. If your motorcycle shock absorbers go bad, it is important to repair them right away.

How do I stiffen the rear shock on my motorcycle? 

If you need to adjust the preload, you will use the tool to loosen the top ring and spin it up. Turn the adjuster ring clockwise until it reaches the top ring and tighten them together.  

How do I adjust the rebound on my rear shock? 

You can make adjustments to the rear shock for preload and sag. Choose the adjustments that create the ride you are looking for based on how much weight it will need to support.  

Will FXR shocks fit a Dyna? 

No, these bikes use different shocks. Using FXR shocks on a Dyna will create too much movement and make it harder to control the bike. You want to stick to shocks that are meant for your bike.
