Introduced in 1990 as a performance package for the C1500 shortbed regular cab pickup, the 454 SS borrowed many of the design elements from the available Sport Equipment Package and added the 7.4L big block V8 from the heavy duty trucks (along with a few other additions). Only available for 4 years, true examples they are relatively rare, but they are often copied. All true 454 SS trucks will be regular cab, shortbed, fleet side trucks with the RPO code B4U.

CUCV II : GMT400 joins the Military
A rarely seen model is the 1987-2001 CUCV II, the militarized version of the civilian GMT400 platform. Only purchased in small numbers by the US military (Only number I have found in my research is around 800 units), with over 3,000 ordered by other governments across the world.
The CUCV II was a modernization of the more well know “squarebody” CUCV. Based almost directly on the civilian version, only specific changes were made for military use. CUCV II’s were not inherently more heavy duty than what was available to everyone else from their local GM dealership.
