# How To Set Pinion Angle on Lowered Truck

by Phil Borges // in

When you lower your truck, the pinion angle changes. This is due to the change in the driveshaft angle, and it can cause vibration issues. To remedy this, you need to set the pinion angle on your lowered truck. The pinion angle is the angle between the driveshaft and the rear axle. If the pinion angle is too high, it can cause vibration issues. If it’s too low, it can cause wheel hop.

To set the pinion angle on your lowered truck, you’ll need to adjust the rear end. First, jack up the truck’s rear end and support it with jack stands. Then, remove the driveshaft. Next, measure the pinion angle and compare it to the factory settings. You’ll need to lower the rear end if it’s too high. If it’s too low, you’ll need to raise it. Once you’ve set the pinion angle, you can reinstall the driveshaft and lower the truck back down.

It’s important to set the pinion angle on your lowered truck to prevent vibration issues. You can easily set the pinion angle on your lowered truck by following the steps above.

## What Should Pinion Angle Be Set At?

The pinion angle is the angle between the driveshaft and the rear axle. If the pinion angle is too low, it can cause problems with traction and handling. It can cause vibration and wear on the driveshaft and bearings if it is too high.

The ideal pinion angle will depend on several factors, including the type of vehicle, the size of the tires, and the suspension setup. A pinion angle between 3 and 5 degrees is considered ideal for most applications. However, it is always best to consult with a qualified mechanic or engineer to ensure that the pinion angle is set correctly for your specific application.

## How Is Pinion Angle Calculated?

To calculate the pinion angle, you need to know the length of the driveshaft and the height of the rear axle. The pinion angle is equal to the arc tan of (driveshaft length / rear axle height).

For example, if the driveshaft is 30 inches long and the rear axle is 20 inches high, the pinion angle would be equal to the arc tan of (30 / 20), or approximately 14 degrees.

No matter what type of vehicle you have, it is important to set the pinion angle correctly. This way, you can avoid vibration and other issues that can cause problems down the road. You can easily set the pinion angle on your lowered truck by following the steps above.

## How Do I Know if My Pinion Angle Is Off?

If your vehicle is equipped with a solid axle, the pinion angle is a critical setting. The pinion is the gear at the end of the axle that meshes with the ring gear, and the angle of the pinion relative to the driveshaft affects how smoothly power is transferred from the engine to the wheels. If the pinion angle is off, it can cause vibration and premature wear on both the drivetrain components and the tires.

So how can you tell if your pinion angle is off? There are a few signs to look for. First, check for excessive vibration while driving. If you feel a strong vibration that seems to be coming from the rear of the vehicle, it could indicate that the pinion angle is off. Another sign to look for is unusual tire wear. If you notice that your tires are wearing unevenly or prematurely, it could be caused by an incorrect pinion angle.

If you suspect that your pinion angle is off, it’s important to have it checked by a qualified mechanic as soon as possible. They will be able to measure the angle and make any necessary adjustments to ensure that your vehicle is running smoothly.

## What Does a Bad Pinion Angle Do?

A bad pinion angle can cause several problems with your vehicle. First, it can cause vibration and noise as the drivetrain components rub against each other. This can be extremely jarring and uncomfortable, and it can also lead to premature wear and tear on these parts. Additionally, a bad pinion angle can cause the wheels to slip or skid when accelerating or turning, which can be extremely dangerous. Finally, a bad pinion angle can negatively affect your vehicle’s fuel economy, as the engine has to work harder to turn the wheels. All of these problems can be avoided by ensuring that the pinion angle is set correctly.

## How Do You Set Pinion Angle Leaf Springs?

The pinion angle is the angle between the driveshaft and the differential. It’s important to set the pinion angle when you install lift kits, superchargers, or any other type of suspension modification that changes the ride height. If the pinion angle isn’t set correctly, it can cause vibration and wear on the driveshaft and differential. There are two ways to set the pinion angle: static and dynamic. The static setting is done with the vehicle on a lift or jack stands, and it doesn’t take into account how the weight of the vehicle will affect the suspension. Dynamic setting is done with the vehicle on level ground, and it takes into account how the weight of the vehicle will affect the suspension. The best way to set pinion angle is with a digital protractor, but you can also use a tape measure and a level. Here’s how to do it:

1. Measure from the center of the rear axle to the center of the front axle. This is your wheelbase.

2. Measure from the ground to the center of the rear axle. This is your ride height.

Once you know your desired pinion angle, you can adjust the suspension to achieve it. If you’re using a tape measure and level, you’ll need to make small adjustments until the pinion angle is correct. If you’re using a digital protractor, you can simply set it to the desired angle and be done.

## Conclusion

Setting the pinion angle on a lowered truck is important to ensure that the drivetrain components don’t experience excessive wear and tear. It’s also important to set the pinion angle correctly if you’re using a lift kit, supercharger, or any other type of suspension modification. Pinion angle can be set statically or dynamically, but the best way to do it is with a digital protractor. With a little effort, you can ensure that your lowered truck is running smoothly and safely.
