There are certain part to ever car that very seldom gets any consideration – or maintenance for that matter. These parts are tasked with keeping your horsepower tied to your car’s chassis, and it’s a thankless job. “Motor” mounts are not only tasked with holding your engine in place, they also absorb engine noise and vibration. When not broken, they prevent misalignment between driveline components under high loads. As you can see, motor mounts perform some very important tasks, yet they rarely get any attention for their work. Until they fail.
Energy Suspension wants to help you keep your mill in place, and do so with a product that is better in many ways than OE. The polyurethane mounts the company has available to enthusiasts not only last longer than the OE rubber units, but do something no OE mount can do — they look as good as they perform.
When an OE motor-mount finally goes bad, you’ll notice a lot of vibration inside the vehicle, increased engine noise, and even excessive engine movement. While all OE-style motor mounts are designed to allow some flex or movement, too much movement can lead to strain on your driveline and even prevent normal clutch and transmission operation. But, are all motor mounts equal? Not according to Energy Suspension.
Join in any discussion about motor mounts, and you’ll soon learn that opinions vary about what makes the best engine mount materials. The reason for this is because the right choice has a lot to do with personal preference. Some folks feel OE mounts break too easily, and some feel the poly mounts transfer too much vibration into the car. While there is a give and take between engine-mount materials and choosing the right mount, often, it comes down to your intended vehicle use.
It’s no secret that rubber engine mounts – like the ones provided by the factory – offer the greatest vibration and noise-dampening effect. And while they do hold the engine in place, their lifespan can be limited. The old rubber-style mounts are prone to cracking and coming apart after a while, and also allow the most engine movement when under load. Although many might not realize it, this means less power is transferred from the engine through the driveline and back to the rear wheels. Basically, rubber mounts are ideal for restorations, but as horsepower is increases, it may be time to upgrade.
Generally speaking, polyurethane is tougher and more rigid than rubber, making it ideal for engine and transmission mounting. This does, however, mean the passengers will feel more engine vibration than with the rubber mounts. Don’t let that statement deter you. The affect is minimal, and you really have to be trying to notice it.
Poly mounts are virtually impervious to oil and fuel, and will not deteriorate. Also, the Energy Suspension motor mounts incorporate a limiting tab that stops them from being torn apart. Polyurethane motor mounts are a great compromise between some of the benefits rubber and some of the benefits of a solid mount.
Unless you’re working on a correct restoration and you’re ready to upgrade your hot rod with better-than-OE motor mounts, then you need to check out Energy Suspension’s polyurethane engine and transmission mounts. This better mounting option awaits your classic or even late-model ride.
