S300 Turbo Kit

The Smeding Diesel S300 Turbo Kit offers a robust solution for 2007-2018 Dodge Ram 2500 and 3500 6.7L Cummins trucks, specifically addressing the common failures associated with the factory HE300V and HE351VE variable geometry turbos. Its fixed-geometry design eliminates the issues caused by soot, carbon buildup, corrosion, and electronic actuator problems that often immobilize the vanes. This kit provides a significant upgrade in performance, delivering quicker throttle response, increased horsepower, and faster spooling compared to the stock VGT turbo. It is constructed for durability to withstand both extreme applications and daily driving. The kit includes the turbo, a T4 divided exhaust manifold, gaskets, mounting bolts, coolant plugs, an oil drain extension, and a turbo drain gasket. For simpler installation, it retains the factory air intake, downpipe, and intercooler piping. For those seeking maximum performance, the S300 kit is available with billet compressor wheels, CNC-machined from solid aluminum. These wheels are lighter, stronger, and spool faster, with the potential to unlock over 650 HP in suitable setups. Options range from cast wheels (62mm, 66mm) to various billet SXE wheels (63mm, 64.5mm, 66mm, 69mm, 72mm SXE-R, 63mm SXE-R). Note that the SXE-R models require a 360° thrust bearing upgrade. The S300 Turbo Kit is designed as a direct replacement for the HE300V/HE351VE turbos and fits 2007-2018 Dodge Ram 2500 and 3500 trucks. It contributes to reduced Exhaust Gas Temperatures (EGT) and drive pressure, helping to protect the engine.
