2005 Chevy Silverado 2500HD LT 4×4 Duramax Crewcab. I have updated this truck extensivly over the past 2 years. Raptor Summit white paint 1 year old. I removed the box for paint and at that time installed a new fuel pump. power washed the frame and painted. rebuilt front end. control arms ,lower ball joints, tie rod ends,steering stabilizer, bushings, shocks, all 4 slotted rotors and pads, new steering box, tires are less than a year old, new caps, removed front and rear bumpers and grill for paint, refurbished factory 6 disc CD player, am/fm stereo, new intrument dash panel, all gauges work and are bright lite original color, A/C and heater work as they should, replaced both thermostats, alternator, belt and belt tentioner. flushed both the cooling system and the allison 5 speed transmission, NO leaks, drives very good . I am aware that some Duramax lovers have issues with the LLY but this truck is an exception to the rule , does NOT heat up even under hard pulls with my 20 ‘ V nose car hauler trailer loade. NO issues with this engine what-so-ever. come drive it and if you are seriously looking for a great truck you will buy it. it has served me well but I have no use for it anymore.. NO deff!!! Tim
