High-quality turbocharger, hot-pipe and charge-air plumbing, oil feed/return lines, brackets, clamps, couplers, and hardware specific to your application. Components are designed to fit with factory accessories and packaging in the 6.7L engine bay.
Designed for 6.7L Cummins Ram 2500/3500 model years 2007.5 and newer. Works with the factory VGT and emissions equipment when installed as directed. Check individual product pages for year-specific notes.
Owners who tow, daily drive, or want dependable power increases with controlled EGTs. If your goal is usable torque and reliability rather than peak dyno numbers, a compound over stock kit is the right path.
Yes. These systems are engineered to stack an S475 or S480 over the factory turbo and route air efficiently so emissions hardware remains installed and functional when the kit is installed as directed.
Some trucks operate well on stock calibration, but many benefit from a calibration update to optimize fueling, vane control, and shift strategy under higher airflow. Use a reputable tuner that understands compound 6.7L setups.
Gains vary by turbo selection, altitude, and fuel system health. The goal of compounds is strong, safe torque with cooler EGTs. Expect a noticeable improvement in pull and sustained grade performance rather than a peaky top-end only increase.
The S475 favors faster response and excellent towing manners. The S480 offers more airflow headroom for higher fuel demand. Choose based on intended use and fueling.
Experienced DIY owners can complete installation with quality tools and time. Professional installation is recommended if you are new to plumbing oil lines, clocking turbos, or aligning charge-air piping.
