Rev Up Your Model Car with Hydraulics: A Comprehensive Guide

If you’re an avid model car enthusiast, you might be on the lookout for ways to make your models even more impressive and eye-catching. One way to do that is by adding hydraulics. Hydraulics allow your model cars to move in ways that are impossible with static models, and they add an extra element of excitement to your collection.

In this comprehensive guide, we’ll explore everything you need to know about adding hydraulics to your model cars.

What are Hydraulics?

Hydraulics use pressurized fluid to create motion or force. In the case of model cars, hydraulic systems can be used to control the suspension and movement of the car’s wheels and body. This means that your model car can have a realistic bouncing motion, like a lowrider, or even jump off the ground.

Types of Hydraulic Systems

There are two main types of hydraulic systems used in model cars: pump and gravity.

Pump Hydraulic System

A pump hydraulic system uses a pump to pressurize fluid and force it through hoses into cylinders. The cylinders then use the pressurized fluid to move the car’s suspension or body.

Gravity Hydraulic System

A gravity hydraulic system uses gravity to move the fluid. In this system, the fluid is contained in a reservoir that sits above the cylinders. As the car’s suspension or body moves, the fluid is pulled down by gravity and into the cylinders.

Choosing the Right Hydraulic System for Your Model Car

When deciding which type of hydraulic system to use in your model car, there are a few factors to consider. One is the weight of the car. If your model is heavy, a pump system might be necessary to provide enough force to lift it off the ground. Another factor is the level of control you want over the movement of the car. A pump system can provide more precise control, whereas a gravity system might have more fluid movement.

How to Add Hydraulics to Your Model Car

Adding hydraulics to your model car can be a challenging and time-consuming process. However, with careful planning and patience, it can be a rewarding project. Here are the basic steps:

1. Plan out the hydraulic system. This includes deciding on the type of system you want to use, mapping out where the hoses and cylinders will go, and determining the size and placement of the reservoir.

2. Assemble the hydraulic system. This involves fitting together hoses, cylinders, and other components. You may need to do some custom fabrication to get everything to fit properly.

3. Install the system in the car. This involves cutting holes in the car’s body to allow the hydraulic hoses and cylinders to pass through. You’ll also need to mount the reservoir in a secure location.

4. Test the system. Once everything is installed, test the hydraulics to make sure they’re working properly. You may need to make adjustments to the pressure or flow rate to get the desired movement.


Adding hydraulics to your model cars can take your collection to the next level. It’s a challenging and time-consuming process, but the end result is a truly unique and eye-catching model. By following this comprehensive guide, you can get started on your hydraulic model car project and create a one-of-a-kind piece that’s sure to impress.
