How to Wrap a Frame for Hydraulics

If you're customizing a car with new low rider hydraulics, or simply repairing an old one, it's important to reinforce any structural weaknesses in the vehicle's frame. Wrapping a frame involves welding stronger steel over the the weak spots in the frame. It is particularly important to wrap the rear of the vehicle's frame, as this is the location of the hydraulics and this part of the frame will have to handle as much as 1000 pounds of pressure. Wrapping the rear of your frame properly will ensure that it can handle the weight.

Instructions

1

Place jack stands under your car and raise it up at the back, so that the rear frame is easily accessible. Since hydraulics are usually located at the rear of a car, this is the most important part to frame properly

2

Examine the rear frame of your car. Look for any obvious structural weaknesses and try pushing down on it in various locations. If the frame bends or moves when you apply pressure, you should plan on wrapping this part of the frame.

3

Weld pieces of scrap steel to car's weak spots. Try to match the thickness of the frame as much as possible; however, it is better if your scrap steel is too thick than too thin as you can grind it down later. Ensure that you weld the steel properly so that it is firmly attached on all sides. Measure your hydraulics and compare your measurements to the car's frame so you know that all the components fit properly. Once you have completed the rear, ensure that the rest of the car's fame is properly wrapped. Although the rear of the frame is the most important part for hydraulics, the rest of the frame must also be strong and durable.

4

Grind the scrap steel down so that the car's frame has a consistent thickness. After wrapping, your car's frame will likely appear lumpy. Try to grind it down to make the frame distribute pressure more evenly.

5

Apply a layer of primer and paint the frame to finish your wrapping job. After painting the frame, you can install the hydraulics and move on to the next step in building or repairing your car.
