Faster Records; Strong Parts
So much of innovation in racing can be boiled down to the concept of trying to hit a moving target—a target that is for the most part going one way: faster. It takes a complex series of functions to increase speeds and lower lap times or ETs, and bearing the brunt of those ever-evolving functions is the race car’s driveline.
“A lot of our products are born out of not just transferring torque but withstanding torque,” said Lee Mejia of The Driveshaft Shop, Salisbury, North Carolina. “People are making a lot more horsepower and torque than what the vehicle was initially designed for, and then they’re finding limitations in the drivetrain that the additional torque has created—twisted up driveshafts, broken axles, and things like that.”
Carbon Fiber vs Aluminum
The choice between a carbon fiber and aluminum driveshaft isn’t as much about weight as racers may think. Carbon fiber is a more torsional material, so it has more capability to twist under load to absorb some of that initial shock during the launch. This, along with its benefits related to weight reduction make it a perfect replacement for OEM Driveshafts. Mejia told us some of The Driveshaft Shop’s customer cars “are making 2,000–3,000 hp, with torque numbers that are pretty far up there as well.
We’ve had to figure out ways of making parts that are torsional enough to withstand that kind of shock and abuse over and over again.”Among those are Aluminum driveshafts for modern domestic muscle cars. Aluminum is a torsional material too, with typically about 15 degrees of twist under load. By doing so, it typically smooths out the launch, helps with some traction, and it can help with wheel hop. No matter the choice in material, our driveshafts are the most durable on the market. Our Shafts are a direct fit replacement. Leave the worry of breakage behind and contact the Driveshaft Shop for all of your drivetrain solution needs.
