When it comes to building a high-performance vehicle or restoring a classic, the driveshaft is the critical link that can make or break your project’s success. Off-the-shelf driveshafts rarely handle the unique demands of custom builds, leading to vibration, power loss, or even catastrophic failure. That’s where Speedway Motors custom driveshafts stand out. With decades of experience serving hot rodders, racers, and restorers across North America, we craft driveshafts that aren’t just parts—they’re precision-engineered solutions tailored to your exact vehicle. Whether you’re building a drag car, restoring a muscle car, or upgrading a street machine, our custom driveshafts deliver the strength, balance, and fit your project deserves.
Speedway Motors Custom Driveshafts: Engineered for Performance and Perfect Fit

Why Speedway Motors Custom Driveshafts Outperform Stock Options

Any seasoned builder knows that a one-size-fits-all approach doesn’t work for performance vehicles. Our custom driveshafts solve the common headaches of generic parts:
  • Perfect fit for your unique setup—no more modifying yokes, hacking flanges, or dealing with alignment issues
  • Balanced for your specific RPM range, eliminating vibration that robs power and damages components
  • Built to handle your engine’s torque output, with safety margins that exceed industry standards
  • Material matched to your application—choose from steel, aluminum, or carbon fiber based on your performance goals
  • Backed by technical expertise—our team understands drivetrain dynamics, not just parts catalogs
For anyone tired of compromising on quality or spending hours troubleshooting drivetrain issues, a Speedway custom driveshaft is the solution that gets your project rolling smoothly.

How Our Custom Driveshaft Process Works

We don’t just sell parts—we engineer complete drivetrain solutions tailored to your build:
The process starts with your project details: vehicle make/model/year, engine and transmission type, rear end configuration, power levels, and how you’ll use the vehicle (street, strip, road course, or show). Our drivetrain specialists then design a driveshaft that:
  • Features the exact length needed, measured from center-to-center of U-joints
  • Includes properly sized yokes or flanges that bolt directly to your transmission and differential
  • Uses U-joints rated for your torque output and service conditions
  • Incorporates slip yokes where needed for vehicles with suspension travel
  • Gets balanced to precision standards (G2.5 or better) for vibration-free operation
Every driveshaft is crafted in our Nebraska facility using CNC machining for critical components, with welds inspected by certified technicians. We handle everything from simple single-piece shafts for street rods to complex two-piece designs for lifted trucks and race cars. Most custom orders ship within 5-7 business days—fast enough to keep your project on schedule.

Material Options for Every Build Goal

We offer three premium material options to match your performance needs and budget:
  • DOM Steel—our most popular choice for classic restorations and heavy-duty applications. 1020 DOM steel delivers exceptional strength at an affordable price, perfect for street-driven vehicles and mild performance builds. Available in 2.5″, 3″, and 3.5″ diameters.
  • 6061-T6 Aluminum—the go-to for weight reduction without sacrificing strength. Up to 40% lighter than steel, aluminum driveshafts improve acceleration and reduce drivetrain inertia, ideal for street performance and road racing. Available in 3″ and 3.5″ diameters with polished or powdercoated finishes.
  • Carbon Fiber—the ultimate for high-performance builds where every ounce counts. Our carbon fiber driveshafts are 50% lighter than steel and incredibly stiff, perfect for drag racing, circle track, and high-RPM applications. Available in 3″ and 4″ diameters with custom end fittings.
All materials meet strict quality standards, with material certifications provided for every driveshaft.

Quality That Stands Up to the Toughest Demands

At Speedway Motors, we build driveshafts like we’re putting them in our own projects—that’s why our quality process is uncompromising:
  • ISO 9001 certified manufacturing ensures consistent quality across every build
  • 100% dynamic balancing on computerized equipment, spin-tested up to 6,500 RPM
  • Torque testing on prototype shafts to verify strength under extreme conditions
  • Magnetic particle inspection of welds to detect hidden flaws
  • Laser measurement of critical dimensions to ensure precise fitment
Every driveshaft comes with a lifetime warranty against defects in materials and workmanship, plus detailed installation instructions and technical support.

Perfect for These Popular Build Scenarios

Our custom driveshafts solve common challenges in these project types:
  • Classic car restorations—replace worn-out original shafts with modern materials that look period-correct
  • Engine swap projects—connect LS, Hemi, or Coyote swaps to vintage or modern rear ends
  • Drag race cars—lightweight aluminum or carbon fiber shafts that handle big power launches
  • Lifted trucks and off-road rigs—two-piece designs that accommodate suspension travel
  • Street rods and customs—clean, polished aluminum shafts that enhance undercarriage appearance
  • Road race vehicles—balanced shafts that maintain precision at high RPMs lap after lap
No matter how unique your build, our team has the experience to create the perfect driveshaft solution.

Real Builds, Real Results

Here’s how our custom driveshafts have transformed our customers’ projects:

1969 Camaro LS Swap

A customer was struggling with vibration in his LS-swapped ’69 Camaro, caused by a mismatched steel driveshaft from a parts store. We built a 3″ aluminum driveshaft with a GM 4L60E transmission yoke and 12-bolt differential flange, balanced to G1.0 standards. After installation, the vibration disappeared completely, and he reported smoother acceleration and a 0.2-second improvement in his quarter-mile time.

1972 C10 Lifted Truck

A truck builder had lifted his ’72 Chevy C10 8 inches, leading to severe driveline angles and repeated U-joint failures. We designed a two-piece aluminum driveshaft with a center bearing, corrected yoke angles, and heavy-duty sealed U-joints. The new setup eliminated the angle issues, and the truck now handles off-road trails without drivetrain problems—something the previous owner thought impossible.

Pro Stock Drag Car

A race team needed a lightweight driveshaft for their 3,500hp pro stock car that could handle 8,000 RPM launches. Our 4″ carbon fiber driveshaft with titanium yokes cut 15 pounds from their drivetrain and balanced perfectly at high RPM. The car picked up 0.15 seconds in the 1/8 mile and has completed an entire season without drivetrain failures.
