Hand holding a racing flag in the air

Here at Repair Masters Automotive LLC, we take pride in our work and that’s why we choose only the best of products for our customers. We already have faith in Jasper Engines and Transmissions because of the products they provide and the warranty that backs them up, but this latest news justifies our choice even more. There are thirty NASCAR® team/driver combinations in 2021 that are using the JASPER 4-Speed Transmission. Of those thirty team/driver combinations, eighteen are being used for the NASCAR® Cup Series and twelve are being used for the NASCAR® Xfinity Series.

According to a Jasper Engines and Transmissions Press Release, “The following NASCAR® Cup Series teams are using the JASPER 4-Speed Transmission in 2021: Stewart-Haas Racing, with drivers Kevin Harvick, Aric Almirola, Chase Briscoe, and Cole Custer. Joe Gibbs Racing, with drivers Denny Hamlin, Kyle Busch, Martin Truex, Jr., and Christopher Bell. Richard Childress Racing, with drivers Austin Dillon and Tyler Reddick. MBM Motorsports, with drivers Timmy Hill and Chad Finchum. Richard Petty Motorsports, with driver Erik Jones. 23XI Racing, with driver Bubba Wallace. Trackhouse Racing Team, with driver Daniel Suarez. Kaulig Racing, with driver Kaz Grala. Live Fast Motorsports, with driver BJ McLeod, and Gaunt Brothers Racing, with driver Ty Dillon.”

The Jasper Engines and Transmissions Press Release also stated that, “The following NASCAR® Xfinity Series teams are using JASPER 4-Speed Transmissions in 2021: Joe Gibbs Racing, with drivers Daniel Hemric, Brandon Jones, Harrison Burton and a fourth driver on a rotating basis. Stewart-Haas Racing, with driver Riley Herbst. Kaulig Racing, with drivers Jeb Burton, Justin Haley, and AJ Allmendinger.

In 2020, JASPER products account for nineteen wins, eighty-nine top-five finished and 163 top-ten finished in the NASCAR® Cup Series. In the NASCAR® Xfinity Series, they accounted for twenty-one of the 2020 wins.
