The Slate SUV kit turns the two-seat truck into a five-seat SUV by adding a roll cage, rear seats, roof, and glass. Since Slate's store restructure, the configurator sells these as complete body styles rather than as a separately priced kit: $29,950 for the Squareback SUV and $31,950 for the Fastback SUV, against $24,950 for The Blank Slate truck — a $5,000 to $7,000 difference. Standalone kit pricing is not currently listed.
How much does the Slate SUV kit cost?
| Body style | Complete vehicle price | Over the truck |
|---|---|---|
| The Blank Slate (truck) | $24,950 | — |
| Squareback SUV | $29,950 | +$5,000 |
| Fastback SUV | $31,950 | +$7,000 |
All plus Slate's $1,450 destination charge. Prices read from the Slate configurator and verified August 10, 2026 — see the accessory price database for the full capture and change log.
What the configurator actually shows now
This is the part that has changed, and it changes how you should read every SUV-kit price quoted elsewhere. Slate's Build & Shop no longer presents the SUV as a priced accessory kit. It presents three body styles — The Blank Slate, the Squareback SUV, and the Fastback SUV — each with a complete-vehicle price. There is no line item on the configurator that reads "SUV kit: $X."
So there are two honest ways to answer "what does the SUV kit cost," and they are not the same question:
- The buy-as-SUV price. Order the Squareback at $29,950 or the Fastback at $31,950 and the conversion is included in the vehicle. This is the only route Slate currently prices.
- The difference-from-truck price. $5,000 for the Squareback, $7,000 for the Fastback. This is the number most people mean by "kit cost," and it is a sound way to think about the value — but it is a subtraction we are doing, not a price Slate publishes.
What Slate does not currently publish is a standalone kit price for converting a truck you
already own, after delivery. That was plausible under the original flat-pack framing, and it may still
be offered — but it is not on the configurator as of August 10, 2026, and we are not going to print a number
for it. [VERIFY standalone kit availability and pricing against slate.auto]
What the SUV kit actually is
The Slate is a truck first. The SUV isn't a separate model — it's the same truck platform with a flat-pack kit that encloses the bed and rear, adding seating for a total of five. Slate offers two rooflines: the squared-off Squareback SUV and the sloped Fastback SUV [VERIFY seating count and roofline details against slate.auto].
Crucially, the kit changes the body only. Battery, motor, range, and capability are the truck's — one 205-mile LFP powertrain underneath every version. If you are weighing the weight cost, the enclosed body eats into the same 1,550 lb budget covered in dimensions and weight.
What's in the kit
The conversion adds the structure and enclosure needed to turn an open bed into a passenger cabin: a roll cage / structural frame, a rear seat, roof panels, and rear side and tailgate glass [VERIFY exact kit contents against slate.auto]. It's shipped flat and assembled onto the truck rather than requiring a welded body conversion.
One practical tell that the SUV bodies are real product lines rather than a paper option: the configurator carries a set of body-style-specific accessories that only exist because those bodies do. If you are budgeting an SUV build, these are the parts that never appear on a truck build sheet.
| SUV-only accessory | Price | Install |
|---|---|---|
| Squareback Roof T-Rail | $124.99 | — |
| Fastback Roof T-Rail | $124.99 | — |
| Squareback Roof Rack | $649.99 | — |
| Fastback Roof Rack | $649.99 | — |
| Squareback Cab Rack Extension | $349.99 | — |
| Fastback Cab Rack Extension | $349.99 | — |
| SUV Rear Armrest | $99.99 | — |
| SUV Rear Bolster Insert | $104.99 | — |
Slate also lists SUV-specific cargo liners and back-seat mats, some of which are still "Price coming soon" — the price database tracks which.
The Open Air Kit is a different thing
Worth separating, because it sits one row away in the same Style category and gets confused with the SUV conversion. The Open Air Kit is Slate's other body kit, listed at $3,950 and rated an Advanced install. It is not a conversion to an enclosed SUV — it's its own body configuration, and it was carried as "Price coming soon" in our July 6 2026 capture before Slate posted a price by August 10.
If you want the enclosed five-seat cabin, that's the Squareback or Fastback. If you want the open-body configuration, that's the Open Air Kit — full detail on the Open Air Kit page.
DIY vs. having it installed
The whole point of a flat-pack is that it's owner-installable — hand tools and a driveway, not a body shop [VERIFY install time and required tools against slate.auto]. Two practical implications:
- It's reversible. Because the kit bolts on, an SUV can generally return to truck form (and back), which is unusual for a body change.
- It affects your build order. If you plan to convert, factor the added enclosed weight into your 1,550 lb payload budget before loading up on other accessories.
Truck or SUV: which to order
Order the truck if you want the open bed, the lowest price, and the accessory-first bed design for racks and storage systems. Order the Squareback or Fastback if enclosed five-seat space is the priority and you're willing to spend $5,000–$7,000 and some payload for it.
The one thing that has genuinely tightened since Slate's store restructure: because the configurator now sells body styles rather than a bolt-on kit, "buy the truck now and convert later" is no longer a documented path with a published price. If converting later matters to your decision, confirm it with Slate before you order rather than assuming the flat-pack framing still means what it meant at reveal.
