Shocks for F350 Super Duty – Buyer’s Guide!

By Kencoul

Hi, I'm Ken Coul, and I was asked to share my view of the best shocks for F350 Super Duty Ford.

As you most probably know, there are three types of shocks that you can buy for your vehicle, and I present them at the end of this guide. Just a quick note though on this, if you want absolute comfort, just add a telescopic strut to your vehicle and retain the OEM suspension.

If, however, you are looking for a real upgrade in performance then add the strut type, which will improve suspension a bit, and finally, if you want a lighter performance for racing, buy a full upgraded spring seat type.

Now, for those of you that are fans of vehicles in the air, remember this, the wheels are what connect your car to the ground. A free flying wheel means you have no control over your vehicle, and as such, you will lose the race.

Good shocks, or even better, the best shocks will keep your wheels firmly on the ground and give you full steerage, braking and acceleration control over your vehicle. Also, take note, telescopic struts are not replacements for suspension, they do not do anything but maintain the tires contact with the surface.

Nuff' said about this, now its time to look at the best shocks on the market for your Ford F350 Super Duty.

Shock Absorber 101

Shock absorbers are designed to help reduce the free flight effect that cars would have when going over irregular surfaces. This means that even if you have a great suspension, your tires will leave the surface of the road when the roll over a rock or branch. The moment your tire leaves the surface of the road, you lose control over everything, including steering, braking, and acceleration. As such, it is highly important for both safety and control that you have the best shock absorbers installed on your vehicle, and for specific applications.

Remember, the suspension is one thing, shocks are another, and you cannot use a standard telescopic shock as a weight supporting suspension device. However, there are solutions to this conundrum for people that seek ways to reduce weight by incorporating hybrid devices. So, let's take a look at the three types of shocks that vary in the level of support they offer your suspension.

Standard telescopic shock absorbers: these do not offer any replacement or support to your suspension. These are classic gas and oil filled tubes designed to keep your tires on the ground at all times. You can buy OEM replacements and upgrade them in the aftermarket too, all dependent on the performance and conditions you are seeking.

Strut type shock absorbers: these offer a little bit of support to your suspension system, as such, when you use these you actually add more comfort to your ride while maintaining a firm grip on the road. These are perfect for haulage and other heavy duty applications and are found on off-road vehicles due to their additional suspension support.

Spring seat shocks: These are full suspension replacement models, and can reduce the weight of your vehicle while adding exceptional suspension support. These have two applications, racing, where you reduce the weight of your vehicle, as well as for heavy duty off-road applications that require both the original suspension and these added suspension bearing shock absorbers.
