Product Description
The ATS 314-008-2104 Billet Direct Piston is a high-performance upgrade for 47RE and 48RE transmissions found in 1996-2007 5.9L Cummins-powered Dodge Ram trucks. Designed to replace the factory cast piston, this billet unit delivers superior strength, durability, and resistance to failure under high line pressure and increased horsepower applications.
The factory direct piston is a known weak point in performance and heavy-duty builds, especially under elevated torque loads. ATS addresses this issue with a precision-machined billet aluminum piston that maintains consistent clutch apply pressure while reducing the risk of cracking or failure.
This upgrade is essential for performance transmissions, towing builds, and any application where increased line pressure and clutch holding capacity are required. Whether you're rebuilding your transmission or upgrading for reliability, this billet piston ensures long-term performance and confidence.
