Absolutely, yes. Shocks reduce the amount of bounce in your vehicle so you have a more comfortable and safer ride. They also help reduce the maintenance cost of your vehicle as they ease the compression and rebound of your suspension system.
When you start feeling those bumps and potholes more, your shocks may not be performing as well as they should. Bad shocks also result in excessive leaning when turning around corners. Other tell-tale signs of bad shocks that need replacing are unusual noises when going over bumps and uneven tire wear.
Gas and oil shocks typically have similar designs and basically work the same way. The difference is that gas shocks have no risk of aeration and enable cooler operation. This results in a more consistent shocks valve rate and smoother operation. On the other hand, regular shocks tend to heat up the oil. This causes the valve rate to change as gas bubbles form and the oil gets foamy.
All shock absorbers generally have the same basic components: pistons, valves, and fluid. However, each type of shock accomplishes tasks differently. Twin-tubes are ideal for highway truck drivers who don’t require much speed but need more support for heavy loads. Gas-charged monotubes are best for frequent off-roaders or those that drive at high speeds because gas shocks have very little risk of aeration and better heat dissipation. So in choosing shock absorbers, always consider how you use your vehicle and the road conditions you frequently encounter.
While both KYB and Bilstein are very reliable brands, they do have slight differences. KYB is popular for its Monomax series built for heavy load tasks, while Bilstein is known for its long-lasting 5100 series shocks. KYB shocks are better at cornering and more affordable but performance-wise aren’t really at par with Bilstein. Bilsteins are generally more durable, provide a smoother and more comfortable ride, and better for off-road driving.
According to most consumers, Bilstein is the go-to brand for any type of shock absorber. KYB and Monroe follow close behind in terms of popularity and reliability. Bilstein shocks are known for their excellent handling of varying loads both on and off-road. Their gas pressure technology and rising rate valving enable shocks to react more quickly to changes in road conditions. Monroe shocks are cheaper but aren’t as heavy-duty as the other two. KYB is somewhere in between in terms of both performance and affordability.
Bilstein is arguably the best brand when it comes to shock absorbers. But for shocks and struts combo, we recommend you go for Detroit Axle. Detroit Axle is known for its high-quality full strut assemblies that improve the stability of vehicles. Their struts effectively absorb vibrations from uneven road conditions, providing a smoother and more comfortable ride.
KYB and Monroe are both known for reliable OEM replacements. In choosing between the two, consider your vehicle type and the conditions you’d be driving in. KYB shocks are generally stiffer and allow you firmer control of your vehicle. These are great for driving on rough terrain as you get less bounce and more control. On the other hand, Monroe shocks are less stiff and provide a smoother ride. They give you better performance on smoother roads.
