4-Speed Transmission
The Jasper 4-Speed transmission has slowly evolved into the best performing transmission on the NASCAR circuit. While there are many racing series around the globe that could benefit from this durable transmission, we first want to tackle the bulk of the NASCAR teams in all three major series.

The Most Reliable Transmission
Since its inception in 2006, the Jasper Transmission, manufactured and designed by Harrah Enterprise, has transitioned from a 3-rail shifting mechanism to a smooth single rail that has proven to be not only the most reliable transmission but also the most aerodynamic. In 2018, it has won nearly every single race in competition this year annihilating its competition. While we know we have the best transmission in NASCAR, we are constantly innovating this piece of machinery and have some cool innovations in the works for the 2020 season.
In the 2018 season, Harrah Enterprise has helped propelled their clients into the Round of 8 in the race for the cup. Six of the final Eight teams are running the Jasper Transmission serviced and manufactured by Harrah Enterprise.​
Championships
This transmission helped Kyle Busch win his 1st championship in 2015 on the way to helping Martin Truex Jr win his championship in 2017. While winning 2 out of the past 3 championships has been an honor, we are hungry for many more championships down the line.
In 2020, this transmission won 25 races and was featured in the car of each of the final four Title Contenders at Miami Speedway. Kyle Busch, Kevin Harvick, Denny Hamlin and Martin Truex Jr shifted this transmission in the final race of the year. Kyle prevailed to win his second championship.
