What are the benefits of an aluminum driveshaft?

Posted 7/15/2016 by Phillip Perez

We get many questions regarding aluminum driveshafts in Mustangs here at LMR. In this article I will go over a few of these benefits with you!

Typical Questions

Some of the questions we usually hear are; “Why should I upgrade to an aluminum driveshaft over my stock unit?”, "Is an aluminum driveshaft really worth it?", or "What are some of the benefits of running an aluminum driveshaft on my Mustang?". Throughout all of the year models there can be many beneficial aspects with upgrading to an aluminum driveshaft.

Aluminum Drive Shafts-Why Should I Upgrade

Overall Weight

Overall weight is one of the biggest benefits when upgrading to one of the aftermarket driveshafts. The lighter weight design will equal a decrease in overall rotational mass. What will this mean? Basically this breaks down to how much physical torque it takes to turn the part. In the automotive field this means a lot when it comes to racing, fuel economy, or even daily driving aspects of your Mustang. Depending on the year of your Stang, you can see a substantial drop in the overall weight and take off characteristics of your ride. For instance, 79-04 can save approximately 4 lbs and 05-14 can save approximately 10 lbs!

Smoother Operation

When switching to any aftermarket aluminum driveshaft on 79-04 Mustang, you will notice a decrease in driveline vibrations and noises. Let’s take the tried but true Fox Body Mustangs. Some being over 30 years old now and still having the factory driveshaft in the car, may have substantial dents, dings, and missing counter weights. All of these factors can cause excessive driveline vibrations and noises. Some of your newer models like the S-197’s use a factory 2 piece design. These can be problematic as well with NVH issues. These models use a replacement 1 piece part that will be night and day different than the stock, but an adjustable upper control arm is just about required to get the pinion angle back in spec on lowered cars to prevent tunnel clearance issues and high speed vibrations.


This is one of the most common reasons that Mustang owners will want to replace their factory units. Not everyone wants a bone stock car to ride in every day. The more bolt-on’s you do to your ride will equate to more overall power of course. The factory Fox is rated around 225 Horse Power and 300 LB-FT of torque. If you have invested in a new top end kit, full exhaust, and full bolt-ons you are well over that stock rating now. Many of us have heard horror stories of driveshafts breaking and causing catastrophic failure on all models of Mustangs. Believe me, this is the last thing you want when you go to the track. This will be one of the BIGGEST reasons to upgrade your driveshaft, and at the same time we STRONGLY recommend a driveshaft safety loop!


I hope this has helped in your decision on why to go with an aftermarket aluminum driveshaft. If there is anything else you may need to know that I did not cover, please feel free to give us a shout.
