    \"K-10\" Blazer Question

    Continuing the questions from the "Carfax" Post....

    Today I received a copy of the "79 Blazer" Sales brochure. It is a 8 page color, with several cool pics.

    There is a picture of the "Blazer Convertible" with a soft top that either rolls-up ("Safari" Position) or rolls down to be completely open.

    Anyway, the specs list a "C10-2 Wheel Drive" or a "K10-4 Wheel Drive". It notes this vehcile is also the sames as the GMC Jimmy Series C1500 and K1500.

    So, what really is a "K5", and what is a "K10".


    PS: I'll scan the brochure if anyone wants to see it
    Thanks,

    We hashed this one out last year- I believe the general concensus was that the K stands for 4x4 and the ten stands for half ton, therefore the K10 describes the chassis. How GM came up with the K5 term is still a mystery....... Maybe some engineer's sense of humor?

    Maybe it is the gross weight capacity of the vehicle. Like most 1/2 tons are 10,000 and maybe the K5 is 5,000. Just a thought.

    The model designation for the 1st gen. Blazer was KA105. I believe that the "105" stood for the wheelbase (104.5"). I think K/5 (this is how it was written on the 1st gen. Blazers, with a slash), is an abbreviation for KA105. These model designations are used by the automaker during product development when the marketing name has not been chosen or finalized. For instance, the new full size GM trucks are GMT800, you do not hear anyone use "Silverado", or "Sierra" in an auto plant.

    I believe the "5" was used to simply distinguish between the 1/2 ton pickups (K10) and the Blazers...kindof how in the later years the Blazers were V1500's and the pickups were K1500's.

    Concerning the "10" representing a GVW of 10,000 lbs, I don't think so in an 1/2 ton truck. You have to get a 1 ton dually to get that high of a GVW rating.
