Why isn’t tube included in the alignment kits?

Our mission is to make professional quality alignments possible on a budget, and one of the most expensive parts is the cost of shipping tube. Instead, most of our kits require the customer to supply roughly 28 feet of 3/4” OD tube, which can usually be purchased locally for less than $40 at almost any hardware or home improvement store. That same tube costs 3-4 times as much once it’s shipped to our headquarters and then shipped again to customers.

What tube should I buy?

Any straight round tube with an outer diameter of 3/4” will work. We recommend 3/4” OD architectural 6063 aluminum round tube with a 0.065" wall thickness. It’s commonly available at home improvement stores, as well as online at McMaster-Carr and other retailers.

How much tube will I need?

The most important dimension is the total width of your car; you’ll need two pieces of tubing (one for the front and one for the back) that will hold the alignment strings 2-6” away from the outer lips of your wheels. That means these two tubes should be roughly as long as the width of your car plus 4-12”. It’s not critical that they be an exact length, as long as they’ll hold the strings on each side of the car.

You’ll also need eight short lengths of tube, four front and four rear, to hang the alignment kit from each end of the car. Again, every car is different, but we usually make each of these pieces 18-24” long.

Measure your car to find the best lengths for it, but you’ll probably end up with a shopping list similar to the following:

  • Two 8’ long pieces of tube.

  • Two 6’ long pieces of tube, each cut into thirds.

Will I need a saw to cut tube?

You’ll be able to save money if you’re willing to make a few cuts yourself, as tube is generally cheaper per foot if purchased in longer lengths. However, you can also buy multiple shorter pieces of tube if you don’t want to cut it yourself.

How long will it take for my order to ship?

We’re a small company and build most of our products to order. Most orders ship within 2-3 business days, or a few days longer if we’re at the track. If our fulfillment time increases, we'll post a banner at the top of the site with more accurate infromation.

What’s this stuff on my plastic pieces?

In order to 3D print the strongest parts possible, we use a mild adhesion promoter at the beginning of the print. This product is water soluble and rinsed off before shipping, but occasionally some remains. If you find any on your parts, just wipe it off with a damp paper towel.
