Lightning Fast Spool-Up. Diesel Power Source, Stocker Twin / Compound Turbo Kit, performs excellent when Racing, Towing, or Sled Pulling, but is so very driveable.

EGT's are typically reduced by 250-400 degrees. 

Horsepower, and torque are increased throughout the entire RPM band, and significantly increased in mid and upper range. Typically increases horsepower by 22%-26%. A 400 HP truck will typically gain appx. 95-105 HP.

Specifically designed to operate awesome from stock horsepower all the way up to 600 horsepower. (If going beyond 600 HP we recommend using the S480 turbo, additional fee will apply.  S480 is good to 700 HP with this kit.)

This Twin/Compound Turbo Kit was designed on cutting edge CAD/CAM Software, using CFD (Computational Fluid Dynamics) Testing.  You will not find a more advanced kit on the market today.  Everything fits like it was built from the factory.

Please note, we HIGHLY recommend you get the AC relocation kit. This requires you to replace the air conditioning lines between the firewall an the front of the truck.. but it makes everything a MUCH cleaner install. Without this kit you need to bend your hard lines and this is less than optimal. 

Kit includes:

  • Air Filter
  • Hot Pipe
  • 2-Piece Downpipe
  • Support Bracket for S400 Turbo
  • New Air Intake tubing
  • Low-Pressure Charge Pipe
  • 1-S475 Turbo (large turbo 75mm compressor wheel/ 96m turbine wheel, 1.32 A/R Housing)
  • Steel Braided High Temp Oil Supply Lines
  • New water line for turbo
  • Stainless steel exhaust tubing, tig welded.
  • Flex Oil Drain Line
  • All necessary gaskets, fittings, bolts, nuts & clamps
  • Heat shield
  • Heat wrap
  • Complete Installation Instructions….and the absolute best customer support on the planet.

 *With this kit you use your stock HE351VE turbocharger*
