Strength You Can Trust for Big Torque Builds

When you start pushing serious power through your 2008–2026 Dodge Ram 2500 or 3500 with a 6.7L Cummins and 68RFE transmission, the stock input shaft quickly becomes a weak link. The SunCoast 68-BIS Billet Input Shaft is designed to eliminate that risk by giving you the strength and durability you need to handle high horsepower and heavy towing demands. Made from billet 300M steel alloy, this shaft offers exceptional yield strength that far exceeds the factory component. It’s heat treated and precision ground for a perfect fit, making it a direct replacement that’s ready for serious work or play without any guesswork.

Engineered for Durability and Long-Term Reliability

SunCoast takes things a step further by gun drilling the shaft all the way through. This process helps reduce internal stress risers that can lead to premature failure, a common problem with conventional drilling methods. Whether you’re hauling heavy loads, running performance tuning, or building a truck that sees both street and strip duty, this input shaft is built to hold up under pressure. It’s a smart investment if you want peace of mind knowing your transmission is ready to handle the power you’re putting down. With this upgrade in place, you can push your truck harder without worrying about snapping a factory shaft when it matters most.
