Cadillac Celestiq Seat Belt Extender
Buckle Up Comfortably in Your Cadillac Celestiq
A hand-built four-seat electric flagship with a lounge in the back and a console running the full length of the cabin. Every Celestiq is commissioned individually, which makes buying any accessory for one a question of confirming rather than assuming. Read the two notes below before you order anything.
The Problem
Space is not the issue in a car five and a half metres long. Geometry is. A full-length centre console runs between all four individual seats, so both front and rear buckles sit down in a narrow channel against it. In the rear, a reclining lounge seat settles a passenger further back and lower than a normal bench would, moving the latch out of natural reach. Add an overcoat and there is nowhere your hand can go to find it without turning round to look.
The Solution
A certified extender lifts the connection point up out of the console channel to where your hand already falls. One click into the car's buckle, one click with your factory belt tongue. Nothing is cut, drilled, or permanently attached, and the car returns to standard the moment you unclip it.
Why safety-first matters here

UK Registered Factory

Exceeds Break-Strength
Built to surpass international break-strength tests for three-point belts.
No two Celestiqs are the same, so we confirm before we ship
The Celestiq is hand-assembled at GM's Global Technical Center in Warren, Michigan, at fewer than two cars a day, with every interior specified one-to-one through Cadillac's Artisan Center. Cadillac itself says no two are expected to be alike. Trim, leather, thread and finish are chosen car by car.
On a car like that, a generic fitment claim is worthless and a wrong-coloured part is worse than none. Send us your VIN, the seat you are fitting, and a photo of your latch plate and interior trim. We will confirm the fit and talk through which finish sits closest to your specification before anything is dispatched.
Four seats, and no center rear position
The Celestiq is a strict four-seater. Two individual rear seats sit either side of a rear console carrying its own touchscreen, so there is no middle rear position and no centre rear belt to extend.
If any listing offers you a centre rear extender for a Celestiq, that listing is wrong. Order by side instead: front left, front right, rear left, or rear right.
Choose the style that fits how you travel
Three styles across our full extender range. Which one you want depends on whether the belt falls short or the buckle is out of reach.
| Style | Best for |
|---|---|
| Rigid | A solid section in 3, 5 or 7 inch that stands upright and holds the buckle above the console line. Usually the right answer in this car, front or rear, because the console is what blocks your hand rather than the belt being short. |
| Regular | Woven webbing in 7 inch or 10 inch adding flexible reach between your belt tongue and the receptacle. The choice when you can find the latch by feel and only the length falls short. |
| Adjustable | Woven webbing with a sliding adjuster covering 9 to 26 inches. Worth considering for a rear seat carrying a different passenger on every journey. |

How it works
Nothing is cut, drilled, or modified. The whole thing takes about five seconds and lifts straight back out whenever you want it gone.
Click the extender's tongue into your seat belt receptacle.
Buckle your seat belt into the extender. Takes about five seconds, no tools needed.
To remove it, press the release button just like a normal belt.
Pick the shortest length that works
We recommend adding only the minimum length you need to buckle comfortably. More webbing is not safer, it just adds slack.
1.Pick the seat by side
Front left, front right, rear left, or rear right. All four are individual seats, so each is ordered separately.
2.Measure to the console top
In this car the useful measure is usually the height needed to bring the buckle clear of the console, not the reach across your lap.
3.Send the VIN
With a photo of the buckle and your interior trim, so we can confirm both the fit and the closest finish.
