Buying Considerations For Choosing The Best Shocks For Harley Sportster

How to Install Rear Shocks on a Harley-Davidson by J&P Cycles

If your motorcycle shock starts to give signs of replacement and you are considering getting one, there are few things to consider before spending that money.

The goal is to buy a perfect product that will suit and serve your motorcycle for a long time.

The truth is, there are lots of shock brands on the market nowadays, and more are still expected to surface.

If care is not taken, the retailer may persuade you into buying what will not work well for your machine.

Sometimes, many brands provide misleading information through their product’s description, luring innocent buyers to purchase the wrong product.

You want great value for your money; hence, you should observe proper care before dashing into the market.

We recommend that you read customers’ reviews or check the third party’s assessment of the brand to make an informed decision.

To be certain you are obtaining the right shock that will serve your Harley Sportster, you can read the buying consideration below from our experts:


One of the most important things to put in mind when upgrading or replacing your Harley Sportster’s suspension is to ensure that the shocks you are getting are perfect for your motorcycle.

Make sure that they have the correct size and are compatible with your motorcycle model.

Do not be in haste to neglect this simple but most important aspect; check the specs carefully to ascertain that the shock is perfect for your particular machine in terms of size.


Another essential thing to consider is the performance of the shocks.

Standard shocks are designed in such a way to handle vibrations and bumps you may experience when riding.

When taking that decision for shock replacement, you indirectly want to improve the performance level.

Standard rear shocks are to offer improved handling and a smoother ride than factory shocks. So ensure you are buying the one that would serve this purpose.

The bottom line is to enjoy a comfortable ride as value for your money.

Any shock that does not provide this feature should not be regarded as anything.

Read customers’ reviews and ratings about the shock on its performance to decide whether it is worth the money.


Quality accounts for a product’s durability! When buying rear shocks for your Harley Sportster, do all it takes to pay close attention to the materials.

You need to find out what material is used for the build-up; are they durable and able to withstand harsh environmental elements, or otherwise?

Due to the rough handling of motorcycles, their parts need to be built out of durable steel or other materials.

Your money is valuable to you, and you will not be happy replacing the same shocks you recently purchase due to low quality.

While some rear shocks have chrome coating, others have black finished.

Try to find out the material used to construct the shocks themselves before parting with your money.


Frame compatibility is another thing to consider when shopping for your Harley’s shocks. Ensure that the shocks you are getting are fitting to the motorcycle’s frame.

The eye-to-eye-measurement of the shock you are getting, including the shock’s stroke length, will help you determine whether they are compatible with the bike’s frame.

It is also necessary to use the right connecting component, like the end bushings and bolts attaching the shock to the frame.


When it becomes obvious to upgrade or replace your motorcycle’s shock, you would want to obtain the particular one that will serve your bike for a prolonged period.
