03-07 Dodge 5.9L Cummins BD Iron Horn S369SXE/76 1.0 AR Turbo Kit

If you are looking for an easy, economical turbo upgrade, or need to replace your tired turbo and aging, shrunken exhaust manifold, then BD's Iron Horn series for your 3rd generation 5.9L Cummins offers a clean, drop-in installation.
The BD Iron Horn S369SXE/80 with 1.0AR Exhaust housing turbo kit offers responsiveness and much greater power potential over stock without breaking the bank! This is more of a performance oriented turbo kit, not recommended for towing heavily unless you can keep your cruising RPM's above approx 1900RPM.

Featuring BorgWarner SX-E cartridges and 2-piece pulse exhaust manifold, BD's Iron Horn turbocharger kits are engineered to give optimal performance while reducing EGT's and high drive pressures. The Iron Horn is available in a number of configurations to match your performance level without compromising drivability.
