Interstate Batteries signed a multiyear agreement with FloSports to become the title sponsor of the elite 410 winged sprint car series, which will be rebranded as Interstate Batteries High Limit Racing. Announced Feb. 11, 2026, the partnership launches at the season-opening SugarBee Blackjack Bash, March 12–14 at Las Vegas Motor Speedway Dirt Track, and replaces Kubota Tractors as the series’ naming rights partner. Interstate executives framed the deal as a strategic way to boost brand visibility and connect with local dealers and customers; company leaders noted its existing motorsports ties, including past driver sponsorships and a primary partnership with Christopher Bell’s No. 20 Toyota Camry XSE for the March 15 NASCAR Cup race.

The agreement represents a commercial and media upgrade for the series and expands High Limit’s distribution for the 2026 season. Every High Limit event will air on FloRacing, six events will be simulcast on FS1, and the series will receive additional linear and streaming exposure via NASCAR’s FAST channel and FloRacing’s FAST/24/7 FAST channels. FloSports and Interstate also said select races and content will be available across broader streaming platforms, including YouTube, Prime Video and Fubo, increasing the series’ reach beyond its core streaming home.

Organizers and stakeholders emphasized the timing and scale of the partnership: High Limit — created by Kyle Larson and Brad Sweet and launched in 2023 — is preparing a 2026 slate of 66 nights at 33 U.S. tracks after producing a similar 2025 calendar and roughly 60 million video views last year. Series co-founders Larson and Sweet welcomed the new title-sponsor relationship, FloSports described the move as validation of the series’ momentum, and Interstate said the sponsorship aligns with its dealer network footprint and will enable local engagement, hospitality and grassroots activation.
