Take a look at this, Big Chief with Final Touches on “Caddy Jack”: Anti-Squat, Instant Centers & Pre-Test Setup for Street/Strip Performance!
🔧 What the Video Is About
The video — titled “anti squat? intersect points? Chief’s doing the last couple things on Caddy Jack before we test it!” — takes you behind the scenes as “Chief” works on final suspension adjustments on the car nicknamed Caddy Jack. The goal: dial in the rear suspension geometry (anti-squat, instant center/ intersect points) before the first real test.
In other words: before putting down big power, you’ve got to get the suspension right. And that’s exactly what they’re doing.
🧠 What Are “Anti-Squat” and “Instant Center / Intersect Points”?
-
Anti-squat refers to the suspension geometry’s ability to resist the rear end “squatting” under acceleration. A high anti-squat setup helps keep the rear geometry stable as the car launches, making the rear tires maintain better grip and reducing unwanted squat.
-
The “instant center” (or “intersect points / IC”) is a key part of defining the suspension’s geometry — you draw imaginary lines through the suspension’s control arms and find where they intersect. That intersection point helps define how torque, load, and force transfers under acceleration or braking.
In simpler terms: where the suspension links meet (the IC) + how they’re angled + where the car’s center of gravity sits = how the car reacts when you hit the gas.
🚗 Why It Matters for “Caddy Jack”
Since “Caddy Jack” is clearly being built for heavy acceleration — likely drag-strip or street/strip work — getting anti-squat and IC geometry right is critical.
-
Too little anti-squat → the rear can squat too much under launch, causing weight shift, poor traction, wheel hop or spin.
-
Improper instantaneous center / link angles → may lead to unstable launches, harsh torque steer, inconsistent 60-ft times, or unpredictable behavior.
By adjusting link angles, ride height, and suspension setup now — before any serious passes — Chief gives “Caddy Jack” its best shot at clean, controlled launches once power is turned up.
🛠️ What They’re Doing Right Now on Camera
According to the video:
-
Final check and adjustment of rear suspension links — aligning them to get the correct intersect points.
-
Dialing in ride height and preload, to match the build’s expected power output and tire size.
-
Verifying that the geometry supports adequate anti-squat — meaning once the car launches, the rear end stays stable, maximizing traction off the line.
Basically: no more guesswork. They’re setting up the chassis geometry to be reliable before the real testing begins.
🏁 What This Means — For Fans and Future Runs
Once Chief finishes — and assuming all goes well — “Caddy Jack” should be ready to hit the track with:
-
Better rear grip and cleaner launches
-
Reduced wheel hop or unexpected suspension movement
-
More consistent 60-ft and quarter-mile performance once power’s turned up
For fans of street/strip and Pro-Street style builds, this setup video is gold: it shows the kind of behind-the-scenes suspension work that often makes or breaks a build — especially once you start adding serious power.
✅ Final Thoughts
Suspension geometry — instant centers, anti-squat, link angles — is just as important as horsepower when it comes to a build like “Caddy Jack.” Doing this right before the first test shows respect for the craft, and improves the chances the build will behave once the throttle gets mashed.
“Caddy Jack” might just end up being a serious contender — but only if every component is dialed in.
