Ram Cummins 6.7L - Aluminum Coolant Y-Pipe (2013-2019)
Ram Cummins 6.7L - Aluminum Coolant Y-Pipe (2013-2019)
Prevent coolant leaks before they happen with this upgraded Aluminum Coolant Y-Pipe for your dual-radiator 6.7L Cummins. The factory plastic Y-pipe is a known weak point—it becomes brittle over time, cracks under pressure, and can lead to catastrophic coolant loss and overheating. This billet aluminum replacement is built to eliminate that risk permanently, with smoother internal flow and reinforced strength where it matters most.
Key Features:
- Billet Aluminum Construction: Replaces the fragile factory plastic Y-pipe with high-strength aluminum that won’t crack or warp under heat and pressure.
- Smooth Internal Flow: Engineered for optimized coolant circulation to help maintain stable engine temperatures.
- Heavy-Duty T-Bolt Clamps: Replaces the factory one-time-use clamps with robust, reusable clamps that ensure a secure, leak-free fit.
- Direct Fit Upgrade: Designed to install easily in place of the OEM unit with no modifications required.
Stop Leaks Before They Start
The factory Y-pipe might seem harmless—until it fails. When it cracks, it dumps coolant fast, leading to potential overheating and engine damage. This Black Bandit Aluminum Coolant Y-Pipe eliminates that failure point entirely, giving you peace of mind whether you're hauling, daily driving, or running a tuned setup.
