After 2003, the Express and Savana had updated front-end sheetmetal similar to the GMT800 light trucks and SUVs, and at the same time, fitted with the LS engines. The remainder of the body was not modified. In 2004 Stability Control (Stabilitrak) was added to all passenger vans. In 2008 the interior was updated and side impact roof airbags were standard on all passenger models. They also offer the E85 Flexfuel Vortec 5.3L V8 engine in both the 2008 Express 1500 Work Van and Passenger Van. The 6.6L Duramax Diesel V8 was added as an option for 2006.
