Ram 3500 Turbo Kit - Wehrli - Twin Turbo Kit S400/Stock - Gun Metal - 03-07 is a compound setup for 2003-2007 5.9L Cummins trucks. Pairing an S400 with the stock Holset, it delivers quick spool, strong EGT control, and room to grow.

Match the top charger to your build: S475/stock for fast response and up to about 750 RWHP with supporting fuel; S480/stock for stronger top-end; S480 with 63/64 or 67 upgraded drop-in primaries for 900-1000+ RWHP potential with proper mods (67 not advised for tow rigs and best on manual-trans trucks). This kit is designed for the OEM exhaust manifold; if using an OEM-replacement manifold (Steed Speed, ATS, BD, etc.), it must be sent to WCFab for custom fitment and lead time begins upon its arrival. Turbochargers are sold separately.
