S400/S300 Triple Turbo Kit for 2001-2016 Duramax uses two S300 and a S400 framed Turbo chargers in a compound application; two atmosphere 300's and one high pressure S400. Used more often than not in full on competition or race use applications this combination is a little slower spooling than the S300 Triple setup but is still street able with proper driving techniques. With proper engine and fuel upgrades this combination can exceed 1400 RWHP. Kits are available without turbo chargers but we will need your turbos sent in for the build process if not purchasing turbo's thru us.
This kit is for Off-Road Competition use only!
This Kit Requires Custom Tuning for proper operation and performance.
We recommend kits to be installed by a qualified diesel performance shop or mechanic.
