What Is the Difference Between CV, U-Joint, and Double Cardan Driveshafts?

Understand how each driveshaft type handles angles, vibration, and performance to choose the right setup for your vehicle.

Driveshafts come in several different configurations depending on the vehicle’s design and drivetrain requirements. The most common types are U-joint, CV (constant velocity), and double cardan driveshafts. Each serves a specific purpose and is designed to handle different angles, loads, and driving conditions.


U-Joint Driveshafts (Standard)

A U-joint (universal joint) driveshaft is the most common and traditional design.

How It Works

  • Uses one U-joint at each end of the driveshaft

  • Allows for movement as the suspension travels

  • Transfers power between components at slight angles

Best For

  • Stock vehicles with minimal drivetrain angle changes

  • Rear-wheel-drive vehicles

  • Applications with low to moderate angles

Pros

  • Simple and cost-effective

  • Durable and easy to service

Cons

  • Can cause vibration at higher angles

  • Less efficient at handling steep driveline angles


CV (Constant Velocity) Driveshafts

A CV driveshaft uses a constant velocity joint, which allows for smooth power transfer even at more extreme angles.

How It Works

  • Maintains a constant rotational speed regardless of angle

  • Reduces vibration compared to standard U-joints

Best For

  • Vehicles with independent suspension

  • Front-wheel-drive and AWD systems

  • Applications requiring smooth operation at higher angles

Pros

  • Smoother operation

  • Better performance at varying angles

  • Reduced vibration

Cons

  • More complex design

  • Typically higher cost than U-joint setups


Double Cardan Driveshafts

A double cardan driveshaft is essentially a specialized version of a U-joint setup that uses two U-joints together at one end, often referred to as a CV-style driveshaft in off-road applications.

How It Works

  • Two U-joints are connected by a centering mechanism

  • Helps cancel out vibration caused by steep angles

  • Commonly paired with a single U-joint on the opposite end

Best For

  • Vehicles with lift kits

  • Steep driveline angles

  • Off-road and modified vehicles

Pros

  • Handles higher angles better than standard U-joints

  • Reduces vibration in lifted applications

  • Strong and durable

Cons

  • More complex than standard U-joints

  • Requires proper setup and alignment

Choosing the Right Type

Selecting the correct driveshaft type depends on:

  • Your vehicle’s factory configuration

  • Driveline angles

  • Whether your vehicle is modified

  • Intended use (daily driving vs. off-road)

Using the wrong type can lead to vibration, premature wear, or drivetrain damage.
