2007.5-2010 GM 6.6L DURAMAX LMM BILLET COMPRESSOR WHEEL FOR POWERMAX TURBO
GT3788VA 848212-5001S / GT3794VA 773540-5001S
Upgrade your 2007.5–2010 GM 6.6L Duramax LMM with a high-performance billet compressor wheel engineered for the PowerMax turbocharger. Designed to fit GT3788VA and GT3794VA models, this 6+6 blade billet aluminum wheel improves turbo response, increases airflow, and reduces turbo lag, offering more efficient boost and improved durability over cast wheels. Billet Wheels improve power and performance by roughly 5-7 PSI (boost power), allow for faster spool-up, reduces visible emissions, and eliminates compressor surge.
Billet wheels are CNC-machined from forged aluminum, delivering superior balance, strength, and performance under extreme driving conditions. Whether you're towing heavy loads or seeking more responsive throttle behavior, this wheel is a must-have upgrade.
