New JASPER Option for Medium-Duty On-Road Trucks

Cummins 6.7L

At Mr Diesel & Auto Repair we offer only the best products to our Cheyenne drivers, that’s why we’re excited to announce the expanded availability of the Cummins 6.7L ISB/QSB Rear Gear Running Complete engine from our partner Jasper Engines & Transmissions. JASPER is the nation’s leader in remanufactured engines and drivetrain products.

If you are experiencing issues with the current engine on your 2013-2018 medium-duty on-road trucks, agriculture, construction, and industrial applications you now have an affordable option for an engine replacement. This engine is available with and without head studs and is completely remanufactured using a standard set of new parts. At Mr Diesel & Auto Repair, we love JASPER products because we know that our customers can depend on the quality of the product while having peace of mind because of the warranty this great company offers.

In addition, JASPER uses dynamometer testing to ensure reliable performance. JASPER tests these engines under varying loads to simulate how they would respond during vehicle operation. The conclusion of the test consists of a final engine run-in and inspection to assure peak performance and operating efficiency.

We know that our Cheyenne drivers will love this new offering from our partner JASPER because it is also covered by a two-year warranty. Components of the engine are covered by a one-year warranty and full warranty disclosures are available upon request.
