American Plains Mudding: Dirtbikes Update Start Time, Countdown
American Plains Mudding runs on a near-weekly update rhythm, and the newest drop is live in the game right now — a big customization release headlined by vehicle interiors. The off-road roleplay world, built around mudding, towing, farming and deep vehicle building, regularly draws about 24,000 players at once, with more than about 7,800,000 favorites and well past about 690,000,000 visits all-time — putting it among the more heavily played driving experiences on Roblox.
The update that went live September 12, 2026 is the biggest customization pass in a while: interior customization for every vehicle built this year, a set of new garage tools, more than a dozen replacement sheds, and a painting quality-of-life change. Behind it, the standout on the calendar is a dirtbikes update opening September 19 — a new vehicle type rather than a general drop, and the one drawing the most sign-ups of any release right now. A further update is already scheduled for September 26. Exact start and end times for every update, past and upcoming, are in the schedule below.
We update this page as the schedule changes. Last updated September 13, 2026.

Current and upcoming events
This week’s update (live now)
This week’s update went live on September 12, 2026, at 9:45 AM ET (6:45 AM PT, 2:45 PM BST) and runs through the morning of September 19, with about 5 days left before the next one opens. It’s a customization-heavy drop: interior customization unlocked for every vehicle made this year, a four-post lift, hydraulic service ramps and an impact wrench added to the garage tools, 13 new sheds replacing the older ones, a painting tweak that highlights the relevant section of a vehicle as you hover the dropdowns, and bug fixes. Around about 36,000 players signed up to be notified before it landed.
The dirtbikes update (next up)
The next release is the dirtbikes update, opening September 19, 2026 in the usual mid-morning window at 9:45 AM ET (6:45 AM PT, 2:45 PM BST) and running through September 26. Built around a new vehicle type rather than a general update, it stands apart from the routine weekly drops — and it has drawn the most interest of anything on the calendar, with about 46,000 players signed up to be notified so far. It becomes the live update the moment this week’s wraps.
The following update
The developer has already scheduled the next drop after that for September 26, 2026, opening in the same 9:45 AM ET slot and running through October 3. Its contents haven’t been announced yet — it’s a placeholder for the following week’s update. Sign-ups are still light this far out, at about 7,700, which is typical for a release more than a week away.
Recent updates (just ended)
The update just before this week’s ran September 5 through September 12, 2026. It opened at 9:55 AM ET and closed with about 33,000 sign-ups. Ahead of that, the August 29 to September 5 update pulled the biggest recent turnout at about 43,000 sign-ups; it opened later in the day than usual, at 1:00 PM ET.
The cadence has held steady: a new update roughly every seven days, each running a full week that ends right as the following one begins, wrapping around 7:00 AM ET on changeover day. Most open in a mid-morning window around 9:45 to 9:55 AM ET, though the late-August update opened later, at 1:00 PM ET. Sign-ups have run in the tens of thousands per update, with the dirtbikes release currently pulling the largest crowd.
