Titan Turbos TTS Gen2 66/67 Turbo for Duramax LLY-LMM

The Titan Turbo Service TTS Gen2 66/67 is a built-to-order turbo for the Duramax LLY-LMM Chevy and GMC heavy-duty trucks. It pairs a 66mm dual-plane billet compressor wheel with a 67mm high-flow turbine (9 or 10 blade) and a 360-degree thrust bearing.

It's a bigger step for more power and sound. Titan adds a non-magnetic stainless unison ring and high-flow vanes, plus a new Garrett VGT solenoid and vane position sensor, and it drops in with no other changes.

Why we like it

• Big power step
• High-flow vanes
• VGT solenoid and vane position sensor included
• Warranty: 1 year / unlimited miles against manufacturer defects
