# What is a double cardan driveshaft?

## What is a double cardan driveshaft?

Double cardan shafts utilize multiple u-joints with a center ball to solve the vibrations caused by an increase in drive line angle. Driveline vibration can occur for multiple reasons. When a vehicle is lifted the angles of the drive shafts become greater.

### What is the ideal pinion angle?

According to Currie, the average car crafter should strive for between 1 and 3 degrees between the tailshaft of the transmission and driveshaft, and 1 to 3 degrees between the driveshaft and pinion. Furthermore, the two angles should be nearly equal (between 1 and 3 degrees), but always opposite (see crude diagram).

#### What is the minimum u-joint operating angle?

1 DEGREE
RULE 1: UNIVERSAL JOINT OPERATING ANGLES AT EACH END OF A DRIVESHAFT SHOULD ALWAYS BE AT LEAST 1 DEGREE.

What is a driveshaft angle and why does it matter?

One of the most misunderstood things in drivetrain technology is understanding the driveshaft angle and what its effects are on a vehicle. We will try to make this as simple as possible. As a driveshaft turns at a given angle, the joint moves in a forward-to-back motion.

Are two piece driveshafts any good?

“A two-piece driveshaft is a great item when built and balanced correctly,” says Denny Bringhurst of Denny’s Driveshafts. Denny also reiterates that two-piece units will allow the driveshaft to maintain a higher critical speed, which is essentially a redline rpm maximum of a driveshaft.

## How do you set the angle of a two piece shaft?

Angle setup for two-piece shafts is similar to the one-piece. All three working angles should add up to zero. The easiest way to do this is to mount the front shaft section so it has zero degrees through the joint at the transmission. The rear shaft may then be treated as if it were a single shaft.

### How do you measure a two-piece drive shaft?

Measuring for a two-piece drive shaft is similar to measuring for a one-piece unit. The major difference involves noting the location of the carrier bearing for the driveshaft joint if one is being used.
