This Converter Hits Harder Than Your Opponent Ever Will

If you’re building a Duramax for one thing, winning, then the SunCoast GM-10531-3D Billet Triple Disc Torque Converter is the weapon you want backing up your power. Built specifically for max-effort applications, this converter is designed to deliver violent launches and unmatched torque transfer off the line. With a 3000–3400 RPM stall range, it’s made for trucks running large single turbos, compounds, or even triples. This isn’t for your tow rig or your daily, this is for the truck that’s built to dominate at the track or in competition. When you drop the hammer, the triple disc clutch locks in like a vise and sends every bit of torque straight to the wheels. It’s been known to break necks and hurt feelings, and that’s exactly the point. If you want real-world performance with no compromises, this converter doesn’t just play the game, it sets the rules.

Precision Calibrated For Peak Stall And Brutal Launch Power

The SunCoast GM-10531-3D Triple Disc Torque Converter is engineered for extreme power delivery in 2001–2016 GM Silverado and Sierra 2500HD/3500HD trucks running the Allison transmission. Designed to support high-performance builds using large turbos or compound setups, this high-stall converter delivers aggressive 3000–3400 RPM engagement that’s ideal for drag racing and competition-only vehicles. Internally, the converter features a billet stator designed to resist damage under high brake stall conditions, especially those exceeding 5 seconds. The triple disc lock-up clutch system provides increased surface area for torque transfer, improving lock-up consistency under full-throttle, high-RPM conditions. CNC-machined billet components throughout ensure structural strength and precise operation during peak loads. This converter is not suitable for towing applications and is recommended only for setups where violent torque application is expected and controlled. Every element is built to withstand the abuse of competitive use while maximizing power output and throttle response. It's the kind of upgrade that doesn't just support performance, it unleashes it.
