Which Jig Size Do You Need? How to Choose Based on Tubing Diameter & Use Case
Share
If you’ve looked at the Chassis Speed Jig lineup and thought, “Alright… but which size do I actually need?” You're definitely not the only one.
This is hands down one of the most common questions we get. And honestly, it’s a good one. Buying the wrong size is frustrating, and nobody wants a tool that’s almost right sitting on the bench.
The short answer?
It depends on how you build.
Let’s break it down in a way that actually makes sense in the shop.
Start With the Tubing You Use the Most
Before you buy anything, ask yourself one simple question:
What tubing size do I work with most often?
That’s your starting point.
If 90% of your builds use the same diameter, start there. Measure it. Don’t eyeball it. Tubing that’s “basically 1.50”” has a way of not being 1.50” when it matters.
Once you know your most common size, choosing your first jig is easy.

The Chassis Speed Jig is designed to match specific tubing diameter. When the fit is right your tabs sit square on the tube, nothing rocks or shifts while tacking, and alignment stays consistent. Life is good. When the size is wrong? You’re back to fighting the setup, which kind of defeats the point.
Common Use Cases (What We See in the Real World)
Here’s common use cases of different size jigs and what we see in the real world.
Race Chassis Builders
Race chassis usually involve multiple tube sizes — sometimes on the same build.
That’s why most race guys don’t stop at one jig. They want:
- Consistent tab placement
- Repeatability across the chassis
- Fewer setup changes mid-build
This is where bundles make a lot of sense.

Off-Road, UTV, and Fabrication Builds
Off-road and custom builds tend to use larger or mixed tubing sizes. One project might be simple, the next might not.
A lot of these builders start with one jig and quickly realize:
“Yeah… I probably need another size.”
Custom Fab Shops
If you’re doing different projects week to week, a one-size approach just doesn’t hold up.
Custom shops usually end up with:
- A small range of common sizes
- Multiple jigs ready to go
- Less time swapping tools and re-measuring
Efficiency matters when time is money.

DIY and Home Builders
Most home builders start with one jig, and that’s totally fine.
But once you get into:
- A second build
- A different tubing size
- Multiple tabs on one project
…that second jig starts looking real helpful.
Why Most Builders End Up Owning More Than One Jig
This isn’t a coincidence. We see the same pattern over and over.
You start with one size, realize it works great, and now wish you had another size on the bench.
Owning multiple jigs means:
- Faster workflow
- Less repositioning
- Consistent alignment across the whole build
And no, it’s not overkill — it’s just practical.

Bundles Are the Smart Option
Bundles aren’t about buying more stuff. They’re about buying what you’ll end up needing anyway.
Builders who grab bundles usually do it because:
- They already use multiple tube sizes
- They want everything set up at once
- They don’t want to stop mid-build and wait on another order
We hear it all the time:
“I should’ve just bought the bundle the first time.”
Buy for How You Build
The right jig size isn’t about one job, but rather about your workflow. Think about what you build now, what you’re likely to build next, and how much you value speed and repeatability (and we’re betting it’s a lot!). The right setup makes everything downstream easier.
