Buying guide for the best shocks for Harley Sportster

Before buying shocks for your bike, you need to consider some factors that are crucial in ensuring you get the right fit.

Height adjustment

Most Harley shocks are adjustable by a few inches depending on the rider’s height from the ground. Most motorcycles go for a lower height than what factory shocks come with. If you’re short, it’s recommended to go for shocks that can be adjusted by about 2 inches so that your foot can easily reach the ground. Adjusting the height can also provide you with better control and confidence as you won’t have to adjust your foot or push down the kickstand unnecessarily like when sitting in traffic or when the lights turn red. All the brands mentioned can be adjusted but their lengths vary.


The standard Harley-Davidson Sportster shocks may cause discomfort when riding and could lead to moderate or even severe back pain. This can hamper riding, especially for old folk. Look for shocks that will smoothen your ride even the bumpiest to prevent back stiffening and the ones that will allow you to maneuver bends and accelerate without much leg movement.


You’ll either find stiff or soft shocks on the market. Softer brands are better than stiff ones; however, it depends on your preference. The best are the ones in between and if you’re going to be riding alone, then you wouldn’t be needing stiffness. Soft shocks are best for the front since they absorb more impacts without causing you any distractions while for the rear suspension springs, a little stiff shock may offer better performance.


A second person is a factor when choosing shocks for your motorcycle because of the difference in comfort levels and risk like bottom-out taking place. An increased load increases the strain on your shocks when you ride past bumps and even worse when you ride on a poor quality road. You should look out for shocks with a higher weight limit and make sure to get rear shock absorbers too.

Bottom out

This refers to when your motorcycle’s lower part hits the asphalt when you’re riding and occurs in automobiles too. When your shocks are adjusted too low, it’s bound to happen. Some shocks may be labeled going down an inch, which could however be incorrect by an inch or two, or even the opposite. Avoid adjusting your shocks too much if your Harley Sportster is already low and prone to touching the pavement when you’re riding.

How do I install shocks on my Harley Sportster?

Shocks provide support to your bike’s rear, so before you go ahead and remove the existing shocks, support your motorcycle first. You can use a frame jack or something similar, this will make it easier to install though it’s not necessary. Loosen the shock’s mounting bolt using a T50 Torx socket and a ratchet. For the mounting bolt at the bottom, use a wrench to hold the nut while loosening the bolt with the ratchet or socket. When you’re done removing all the springs’ bolts, it’s time to install the new shocks.

First, before putting the shock in location put a small amount of medium strength Threadlocker on the upper shock’s bolt and the bolt’s threads. Then adjust the jack to raise the swing arm to allow you to align the shock eyelet to the shock mount. Go ahead and install both the bolt and nut then twist the upper and lower shock bolts to about 50ft.


What’s the difference between 10.5 inch and 12-inch shock absorbers?

Shock absorbers come with different heights depending on the manufacturers. The difference might not be that distinctive before installation, but after, you may see it in the motorcyclist’s landing height. It tends to affect the maneuvering of bends and speed performance. 10.5-inch springs enhance the bike’s looks by making them lower and sportier. 12-inch springs on the other hand are ideal for riding on good urban roads.

For a smooth ride, what are the best shocks?

The best shocks to give you a smooth ride normally have a height of 1.5 to 12 inches which is small and enough to handle the most unbearable shocks that come with maneuvering around the city. For springs that not only need to be used on urban roads, but taller spring models like the Burly Brand Shocks are also the most ideal since they come with a height of 13 inches.


A good shock absorber is the difference between a smooth and seamless corner maneuver while preserving your back. Vibrations are best handled by shock absorbers with 2 strings or compressed gas inside them. The above review list gives you an idea of the most ideal shocks for your Harley Sportster. They’re affordable and give excellent performance.
