Hi, the Lentech VB is a nice system, it is sold as a complete VB assy, in 3 different calibrations, there is a fair amount of work to installing a Lentech system, the OD delete button must be installed ( where ever the driver wants) ( and is sold seperatly, about 50$ if I recall) and the trans case itself has to drilled and tapped for the wiring to go through, and I do agree with the last post, " holding second gear " is a nice feature. The Transgo kit is just that,a kit, it not just a seperator plate, you will have some time installing a Transgo HD kit and if you know how to read instructions and a oil schematic you can do alot with this kit, as far as a shop ordering a Lentech VB? I don't know if they would or not, you might ask, you could always order it yourself? PZ
