The 2024-2026 L5P / L5D Stealth STR Turbo by Duramaxtuner.com is specifically designed for the 2024, 2025, and 2026 Chevy Silverado and GMC Sierra 2500, 3500, 4500, 5500, and 6500 models as well as 2024+ International CV (Medium Duty) models.
Don't Just Replace Your Stock L5P/L5D Turbo!
There's no better feeling than getting to upgrade your parts instead of just replacing them. That's exactly why Calibrated Power made the Stealth STR for 2024, 2025, and 2026 6.6L L5P Duramax's. Designed to improve turbo performance and reliability while still coming in around the cost of a stock turbo replacement.
The STR has also been designed with easy tuneability in mind. Unlike other "drop-in" upgrades that require much more than just dropping in a turbo to get up and running. The STR requires no custom tuning to get up and running and has been designed to be as simple to tune for as possible. Say goodbye to lengthy tuning and multiple tune revisions!
