🔥 Performance & Reliability
Unlike conventional pulleys, this 2-piece system reduces rotating mass while increasing stability under boost. The result? Faster revs, cleaner belt tracking, and more consistent performance when the turbos are pushing their hardest.
The Nachi high-speed bearings ensure whisper-quiet operation and reduced parasitic drag, while the precision balancing eliminates vibration — even at redline. The hard anodized finish resists heat cycling from the M157’s extreme operating environment, ensuring long-lasting performance and appearance.
🛠️ Installation Made Simple
This pulley set aligns directly with OEM brackets and belts for a hassle-free install. Whether you're upgrading at home or in a performance shop, the 2 Piece Billet Pulley Set installs in under an hour and immediately sharpens throttle response and drivetrain smoothness.
