Fleece 63 mm FMW Duramax VNT Cheetah Turbocharger | 2011‑2016 LML Silverado/Sierra 2500‑3500
Upgrade your LML with the 63 mm FMW VNT Cheetah-a 100 % stock‑appearing, drop‑in turbo that pairs a forged‑milled‑wheel billet compressor with a high‑flow turbine to deliver lightning spool‑up and 650 RWHP potential while safely running 40‑45 psi of boost. All factory VGT functions stay intact, so you keep the exhaust brake and quick warm‑up but gain the top‑end airflow your dual‑purpose truck demands.
