Midnight
Restraint, rendered in shadow.
A black crown marks the death of a king — and the birth of a legend. We don't accessorize trucks. We resolve the distance between what a vehicle is and what it should have been — until it carries more presence, and more worth, than the day it arrived.
Tap what you want done and the estimate builds itself — the drive out is already in every number.
Labor only — the drive out is already in the number. Parts are quoted separately to your exact year, make and model, or bring your own and we fit them at the same rate. Add 7.5% tax at invoice. 50% books the slot and orders the parts. Not equipped for gooseneck or fifth-wheel.
Every quote already includes the trip out to you inside 30 miles. Two or more installs at the same visit is still one drive — so everything after the first comes in $95 under its own price.
Year, make, model, cab and bed and a written number comes back the same day. Nothing is firm until fitment is confirmed. 50% books the slot and orders parts, balance on completion.
Not quoted on day one. Dealers and fleets start at standard and earn the partner rate after ten units.

From a quiet darkening to a commanding street presence — a commission for every owner, each built to leave the vehicle worth more than it arrived.

Restraint, rendered in shadow.

No chrome. All presence.

Yours alone — built to your hand.

Presence that enters the room first.
Starting points shown — every commission is shaped in consultation, tiers blend, details are chosen, and no two crowns are alike.
Right now we’re a fully mobile upfitter — we roll out to your lot or driveway with select parts and finish on site. A dedicated shop is in development; the builds that need a bay join the menu the day it opens.
Our reputation isn't ours to write — it's our customers'. Every review lives on Google, unedited and in their own words. Read them straight from the source.
"A black crown signifies the death of a king. Not an ending — a passing of power."
Black Crown Diesel was named for that exact idea. Every truck that comes to us arrives as it left the lot — ordinary, expected, uncrowned. We end that life and begin another.
Blacked-out badges. Murdered chrome. Lighting, stance, presence. When the build is done, the old truck is gone and a new one takes the throne. That is the coronation we perform — in darkness, by hand, on your terms.

A vehicle is read before it is understood — at ten feet, from across a lot, in the space of a glance. We call that the Ten-Foot Verdict, and it is the standard every commission must pass: the machine has to carry more presence, and more worth, than the day it arrived. Seven years across dealerships and specialty shops taught us exactly where that line sits — in panel gaps, in stance, in finishes that hold. Nothing leaves until it clears it.
01
Every element sits as though the factory intended it — gaps true, lines unbroken, torque to spec. Nothing reads as added; everything reads as designed.
02
Lighting and electronics integrated to OEM discipline — loomed, fused, sealed, invisible. The result looks engineered, never installed.
03
Every commission is scoped and documented in writing — considered, transparent, accountable. The only surprise is how finished it looks when it's done.
We come to you — driveway, ranch, or dealership lot. Pricing is confirmed before a hand is laid on the vehicle, and a simple commission deposit secures your place on the calendar.
Serving Seffner and the surrounding region — typically within a 30-mile radius.
When a vehicle needs to look — and sell — like more than it cost, dealers call Black Crown Diesel. I add the presence that lifts perceived value and moves units faster: scoped, installed, and delivered end to end, with your name protected at every step.
Owner-Operator · On Every Job
I'm not a call center or a rotating crew. I'm the person who quotes your vehicle, builds it, and stands behind it. Bring me into your process and I'll run your accessory work like it's my own name on the line — because it is. Give me a deadline and I'll beat it; put me in front of your customer and the vehicle will speak for itself.
Let's make your inventory impossible to ignore.
Anyone can promise a discount on the first call. This one is priced on a track record — yours and mine.
No minimums, no contract, no volume you have to commit to up front. You try one vehicle and judge the work on the work.
Delivered on time, to standard, invoice by invoice. Ten is the point where we both know how the other one operates.
A standing discount on every install and Net-15 invoicing, held for as long as the work keeps coming. Earned once, kept for good.
Ask for the dealer rate card and you will get the standard column with the partner column printed beside it — so you can see exactly what the tenth unit is worth.
Tell us about the vehicle and what you have in mind. We respond quickly — with details, pricing, and a time that suits you.
