WHAT GM SHOULD HAVE BUILT
torque based on similar builds they have done. To further dress up the engine they installed a powder coated HSP Diesel thermostat housing and a PPE Diesel lower oil pan.
The Duramax engine is backed by a 2007 Allison transmission that was given a performance rebuild with Suncoast internals and upgrades by the Linco Diesel Performance team. A billet Suncoast
2,200 rpm stall torque converter provides the critical link between the Duramax engine and the Allison transmission. The transmission case was powder coated gloss black while the cast aluminum PPE deep sump trans pan was powder coated candy blue. A Derale Performance transmission cooler keeps the fluid temperature in check while a gated Winters Sidewinder shifter controls gear selection. Before rebuilding the NP261XHD transfer case they had the case halves powder coated candy blue then reassembled it and bolted it in behind the Allison trans. Custom drive shafts were fabricated by Inland Truck Parts in St. Charles, MO to send the power to the front and rear axles.
