JASPER Driveline Division Prepares for 2015 Racing Season

A new year of racing is upon us. The Driveline Division of Jasper Engines & Transmissions looks to build upon an impressive 2014 NASCAR Sprint Cup Series season. Five of the top 10 drivers in the 2014 final points standings drove cars equipped with JASPER products: Denny Hamlin finished third, Joey Logano was fourth, Brad Keselowski was fifth, Matt Kenseth was seventh and Kyle Busch was tenth.

Sprint Cup Series cars equipped with JASPER products accounted for 16 wins in 2014, 72 top-five finishes, 125 top-ten finishes, and earned 15 pole position starts. “Everyone was very satisfied with our products in 2014,” says Terry DeKemper, JASPER Driveline Division Manager. “We’re definitely looking forward to 2015."

Preparing for the 2015 racing season has left the division little time to reflect on previous success. Joe Gibbs Racing drivers Denny Hamlin, Kyle Busch, Carl Edwards and Matt Kenseth will have their cars equipped with the JASPER traditional three-rail 4-Speed Transmission. Michael Waltrip Racing drivers Clint Boyer and Brian Vickers, along with Furniture Row Racing driver Martin Truex, will use JASPER’s single-rail version of the 4-Speed that allows a single external rail to rotate and move two internal forks to engage the four forward gears. Penske Racing teammates Brad Keselowski, Joey Logano and Ryan Blaney, will have their Sprint Cup Series cars equipped with a JASPER Differential for 2015.

“These race teams choose JASPER for our quality, durability and longevity with no component issues,” said DeKemper. “That’s huge when you try and run for a Championship… You can’t afford to fall out of one race.”

The JASPER Driveline Division has worked with race teams in response to NASCAR’s implementation of tapered spacers on Sprint Cup Series engines for 2015. The spacers reduce engine horsepower and DeKemper anticipates a busy year ahead as transmission gearing is expected to dramatically change at each event. “The engines will make about 150 horsepower less than last year, and it will be vital for drivers to maintain high engine RPM during the race,” he said. “We’re expecting drivers to do a lot more on-track shifting, even at tracks where they do not normally shift gears.”
