New Hampshire's Original Diesel Performance and Repair Specialists
General Motors Duramax
In 2001 GM came out with the LB7 Duramax, it was 6.6L of revolutionary technology for the diesel pickup industry. The LB7 was the replacement of the doggish 6.5L Detroit that GM had been using in various applications since the 80s. One major selling point is the Allision Transmission that is found in Duramaxs still today.
