WARNING: This page is about a different car, the 2017 RAM 2500 HD. However, it is still accessible from the selected car via links, so may be relevant.
The piston is constructed of aluminum and is gravity cast, free floating design. The piston incorporates a centrally located high swirl combustion bowl, and utilizes a "keystone" style top compression ring, and a "Tapered Face" intermediate ring, for superior cylinder wall scraping. Piston cooling nozzles cool the piston and pin with engine oil supplied by the crankshaft main journals. All pistons are gallery cooled and utilize J-jet piston cooling nozzles. Pistons are directional in order to provide clearance to piston cooling nozzles.
