Beshore began his career in NASCAR working for smaller teams, eventually joining
Brewco Motorsports as a jack-of-all trades, working as the car chief, engineer, and rear-tire changer for the #66 car in the
NASCAR Busch Series. After moving over to
Roush Fenway Racing in 2007 as a race engineer, he joined
Joe Gibbs Racing in 2014, serving as the race engineer for
Kyle Busch in the
NASCAR Cup Series from 2015 to 2018. He served as the interim crew chief on Busch's car for three races in 2017 when regular crew chief
Adam Stevens was suspended after a wheel came off the car following a pit stop at
Dover International Speedway. Beshore himself was later suspended one race for lug nut infractions suffered at
Sonoma Raceway, leading to Busch's third crew chief in five races. Beshore was named a crew chief for Joe Gibbs Racing in the
NASCAR Xfinity Series in 2019, where he worked with multiple drivers in the program's No. 18 car. He moved over to the No. 20 car for the 2020 season, working with
Harrison Burton. The duo won four races in 2020 as Burton won the series' Rookie of the Year award despite Beshore having missed a race due to possible exposure to
COVID-19. Beshore was promoted to the
NASCAR Cup Series before the 2021 season to work with Busch once again, this time as his crew chief. The duo won their first race of the season, the exhibition
Busch Clash at the
Daytona International Speedway in a shocking last-lap pass as Busch passed drivers
Ryan Blaney and
Chase Elliott who wrecked coming out of the last turn. Beshore earned his first career points-paying Cup Series race in May when Busch won at
Kansas Speedway on his 36th birthday, also extending a record-tying streak of 17 consecutive seasons with a win for the driver. On October 10, 2021, NASCAR announced that Beshore would be suspended for the
Texas race after the No. 18 had two loose lug nuts following the
race at the Charlotte Roval. On October 18, 2022, Beshore was suspended for four races for a loose wheel violation at
Las Vegas. On December 8, 2022, it was announced that Beshore would move back to the Xfinity Series for the 2023 season, this time as crew chief for
John Hunter Nemechek in the No. 20 car. After nearly a decade with Joe Gibbs Racing, it was announced on November 13, 2023, that Beshore would return to the Cup Series with
Legacy Motor Club's No. 42 car with Nemechek in 2024. Upon the departure of Dave Elenz from LMC on October 8, 2024, it was announced that Beshore would move over to the 43 team to partner with
Erik Jones for the remainder of the
2024 NASCAR Cup Series season. On November 19, 2024, LMC announced that Beshore would crew chief the 43 team with Jones during the
2025 season. ==References==
