The remanufactured engine uses Jasper-designed pistons that have improvements including increased strength and durability
Jasper, Ind.—Jasper Engines & Transmissions has announced the availability of its RAM 6.4L HEMI engine. This engine is available for the following applications.
- 2014-2017 RAM 3500-5500 (Cab/Chassis)
- 2014-2017 RAM 3500-5500 (Pickup)
“Our remanufactured 6.4L HEMI engine uses Jasper-designed pistons that have many improvements, increasing both strength and durability,” said Jasper New Product Development Group Leader Brad Boeglin. “These pistons are forged with a better engineered design, including a thicker and anodized crown, with a 10% increase in the skirt thrust area. The skirt is coated with an abradable material, giving the piston the best possible cylinder-to-wall clearance.
“The 6.4L HEMI engine is also prone to lifter roller failures. To help alleviate this issue, Jasper installs a new, improved roller bearing assembly in every lifter. Also, since Jasper uses forged pistons in this engine, which run cooler in-cylinder temperatures, the piston jets are rerouted to spray additional lubrication in the lifter cam area.”
