AMS Performance Race X Billet Flywheel Nissan GT-R 2009-2021 | ALP.07.03.0011-1

Product Fitment:

2009-2021 Nissan GT-R

Engineered for strength, precision, and championship-level durability, the AMS Performance R35 GT-R Billet Flywheel is a true upgrade over the factory unit. Featuring a one-piece billet 4140 chromoly steel design with an integrated flywheel sensor ring, this innovative solution eliminates the need to reuse the OEM two-piece flywheel and separate reluctor ring.

Developed through extensive real-world racing experience, this flywheel is built to withstand extreme power levels without cracking—an issue commonly seen with the factory component. By altering rotational harmonics, it also helps prevent fretting between the flywheel and crankshaft mating surfaces, protecting your engine from long-term damage.

🔧 Key Features

• One-Piece 4140 Chromoly Steel Billet Construction

• Proprietary Heat Treatment Process for Added Strength

• Integrated Flywheel Sensor Ring (No OEM Ring Reuse Required)

• Completely Replaces OEM Two-Piece Flywheel & Reluctor Ring

• Superior Crack Resistance vs. Factory Unit

• Reduces Fretting Between Flywheel & Crankshaft

🏁 Engineered to Win

Designed and refined by the AMS SnailWorks® Engineering Team, this billet flywheel represents countless hours of R&D focused on performance, reliability, and ease of installation.

Unlike the OEM two-piece setup, this first-of-its-kind integrated design incorporates the reluctor wheel directly into the flywheel. The billet 4140 chromoly steel construction offers dramatically improved durability and corrosion resistance compared to the factory unit, which is known to crack or “spider” from the crank hub under high load conditions.

By modifying the harmonics of the rotating assembly, this flywheel helps minimize surface movement between the crankshaft and flywheel—reducing the risk of fretting and ensuring long-term reliability in high-horsepower applications.
