Here are some actual hard facts as to what model vehicles and specific changes.

The GM Gen V 5.3L GDI JASPER engine is available for the following Chevrolet and GMC applications:

• 2014-2018 Silverado, Sierra

• 2015-2018 Tahoe, Suburban, Yukon

• 2016-2018 Silverado, Sierra (Hybrid)

JASPER’s pistons have been redesigned with a larger 4.00 mm oil ring, compared to the OEM 3.00 mm oil ring, for improved oil control and they have added five times more oil drain back through the pistons that will help return oil to the crankcase, reducing the chance of ring sticking.

The fuel pump lifter is located in the valley of the engine and will be supplied with each JASPER remanufactured unit. GM also relocated the PCV from the valve cover to the LOMA board with a ‘shaker valve’ which will also be supplied on the JASPER engine.

The GM Gen V 5.3L GDI engine is covered by JASPER’s 3-Year/100,000 mile nationwide transferable parts and labor warranty.
