What does this mean?

Discussion in '1973-1991 K5 Blazer | Truck | Suburban' started by **DONOTDELETE**, Apr 2, 2002.

    In the slip that's attached to the inside of your glove box that says what options your truck has one of the options on mine is the "Heavy Duty Chassis" but my truck is a K20 not a K30 so what does this mean? Thanks foryour help.

    I don't know. But if I could buy that slip and put it in my Blazer I'd feel better!

    The HD-option includes stiffer rear spring, a higher GVWR, 8-bolt axls, higher axle ratio, more efficient brakes, cooler for transmission and engine and I think, but not surly, a stronger frame…
