Kingpin 400/400 Twin Upgrade

Kingpin 400/400 Twin Upgrade

Proposition 65

WARNING: Cancer - https://www.p65warnings.ca.gov/

Ready to step up to the 'Kingpin' kit and take your 2G single swap to the next level!  This was created out of need for those who weren't able to step right into a twin kit, but have our single swap and are now ready to make the next move.

This kit will make the most of your current SD 2G single swap parts and convert to a twin set up, by saving you money & utilizing most of your current parts. *This kit works with 'most' aftermarket manifolds - please inquire if not using our manifold.  This kit will require the manifold charger to have a v-band outlet cover.

Parts list for 400/400 kit:

  • Twin air intake pipe  ( 5.9 ) year defined.
  • New air filter
  • Turbo boot ( 5.00" or 5.00" -5.50")
  • Oil Feed line
  • Twin oil drain line kit
  • Full set of turbo gaskets (oil drain, turbine inlet for both turbos)
  • Twin turbo bracket
  • Twin down pipe & v-band clamp
  • Cold pipe with O-ring & v-band clamp
  • Boot for 'Cold pipe to Turbo' (3.50" - 5.00" reducer OR 3.50" to 5.50") & t-bolt clamps
  • Hot pipe (welded & wrapped) & v-band clamp (4.62)
  • Optional cold-pipe v-band to compressor cover available (call for details)


*This kit is assuming you are going from a Stainless Diesel S400 2G Single Swap kit already & just need the parts to turn what you have into a 400/400 Knuckle Sandwich Twin Kit* 

SPECIAL NOTES:  v-band cover needed
