Top reasons why you should consider a Simard instead of a factory twin steer suspension

This is a good question! Why should you buy a third-party tandem steer suspension while you are able to order one from your dealer?

First of all, let’s talk a little about history…

Simard Suspensions is a Canadian company and began its activities as a forge back in 1935. In the 70’s and 80’s, there were some heavy trucks equipped with twin steer axles, but there was no load distribution between them. Because of many accidents, the authorities decided to create a committee to find innovative solutions to avoid these dramatic situations. The president of Simard Suspensions was a member of that committee and had the idea of the tandem axle suspension allowing load distribution between axles.

So Simard Suspensions invented the equalized twin steer suspension system and filed the “tandem axle suspension for vehicle” patent in Canada and in the USA.

You may say: “Yes, but that was in the 90’s! What about today? Why should I choose your suspensions systems?”

You’re right, nowadays some trucks manufacturers offer their own twin steer suspensions. Let’s see what makes, a Simard the right choice.

First, we are a suspensions manufacturer; we are dedicated to offering the most innovative products available on the market. It is like going to a doctor; he or she may give you some common solutions but for special diseases, your are sent to a a specialist! And that is exactly what we are!

Some truck manufacturers offer the common 72″ front axle spacing…and that is it! That is a far cry from customizing a system for your unique needs.

The main purpose of a truck manufacturer is to sell you a truck and not a suspension system. Especially in the Class 8 truck market, manufacturers don’t have the time to address customers’ distinct needs when it comes to their vocational trucks!

Don’t get us wrong: standard suspension systems can do the job; however, is the 72″ axle spacing the best choice for your application? Will you get the best load distribution? And even if so, is it the best suspension system you can get for the truck you’re going to drive for years and years ? That is the question…and there are several answers we give to these questions in regards to our suspensions.
