Walpole, NH — In a joint announcement today, Granite State Pro Stock Series President Mike Parks and Lee USA Speedway General Manager John Esburnett revealed that the Keen Parts 150 will now be sanctioned and promoted by the Granite State Pro Stock Series (GSPSS). The event is scheduled for Friday, September 19, 2025, at Lee USA Speedway in Lee, New Hampshire.
“With the recent cancellation of our event at Riverside Speedway in Groveton, we felt it was important to add another race to our 2025 schedule,” said Parks. “Given the continued success of our partnership with Lee USA Speedway and the strong working relationship with track owner Ben Bosowski and General Manager John Esburnett, this was a natural fit.”
The Keen Parts 150 will be a marquee event for the series, offering an impressive $10,000 to win, thanks to the generous support of event sponsor Keen Parts. The race is expected to draw top-tier Pro Stock talent from across the region.
“This is another big step forward for the Granite State Pro Stock Series, and we’re thrilled to return to Lee for such an exciting event,” Parks added.
Further details on race day schedule, format, and additional divisions will be announced in the coming weeks.
Mark your calendars: Friday, September 19th — the Granite State Pro Stock Series returns to Lee USA Speedway for the $10,000-to-win Keen Parts 150.
