2006 Duramax 4x4 LBZ / 6 speed Allison

I have been looking to buy a diesel for a couple months... was planning on buying a Cummins / 6 speed manual truck. I was having trouble finding this combo in 4 wheel drive with a quad cab. I ran across a great year, 100% stock (06 - 360hp / 650ft tq LBZ 6 speed Allison) Duramax at a good price and couldn't pass it up!

Didn't have it very long before the modding started ;-) So far this is what I have done to the truck:

  • Trans Go Jr. performance shift kit for the Allison
  • 4" Custom Exhaust / single 5" Black MBRP stack (no muffler)
  • Self tuned with HP Tuners (approx 100rwhp high rev / low tq increase tune... trans and TC tweaking)
  • Edelbrock 1792 custom lift pump setup (Essex)
  • BD Fuel filter setup ~ 2 micron (factory filter/housing/wif sensor delete)
  • Homebuilt 3.5" Downpipe
  • Homebuilt Intercooler pipes (both sides, EGR delete, Grid delete, 3" hot side)
  • Homebuilt CAI (battery relocation) short piping, custom MAF flange, heat shield, scoop into fenderwell (AMSOIL filter)
  • Black Moto Metal 951's (16x8)
  • Edge Evo  w/ EGT (only using for gauges)
  • Autometer Ultra light oil temp
  • Autometer Ultra light (carbon fiber) EGT
  • ISSpro blue 30psi Boost Gauge
  • PPE Stainless Tie Rod Sleeves
  • Homebuilt Traction bars
  • Extended shackles 6" to drop back 3" (to match front)
  • Blacked out grill / emblems 
  • PCV mod (vent to atmosphere)
  • Switched to 5w30 Mobile1 synthetic in the T-Case
  • Harman/Kardon Drive + Play
  • Garmin Nuvi 765t (widescreen, traffic, etc.)
  • Cobra CB / short ant.
  • Uniroyal LT265/75/16's (sad when that's larger than the stock tires)
  • AMSOIL synthetic engine oil / AMSOIL Torque-Drive Trans fluid / Mobile1 Synthetic diff fluids / AMSOIL diesel librication additive
  • VIDEOS
