Last Wednesday, we talked about Curb Weight, GVWR, GCWR, GAWR, payload capacity and how “tonnage” slang terminology is not reality. Now, let’s put all of that great knowledge to use by deciphering the name’s of Ford, Chevy, and GMC trucks. The automotive slang is in quotes for your reference. To determine which truck you have, just look at the 5th digit of the VIN number. This is the digit of the VIN that tells you the series of the vehicle. For Chevy and GMC full size trucks built after 1980, it will be C, K, R or V. Oooooh, a secret code? Read on….
Chevy C/K Trucks
C-Series Truck = 2 Wheel Drive (1960-2002)
K-Series Truck = 4 Wheel Drive (1960-2000)
C10 = “½ Ton” 2wd (1960-1987)
C20 = “3/4 ton” 2wd (1960-1988)
C30 = “1 Ton” 2wd (1960-1988)
K10 = “½ Ton” 4wd (1960-1987)
K20 = “3/4 ton” 4wd (1960-1988)
K30 = “1 Ton” 4wd (1960-1988)
C1500 = “1/2 Ton” (1988-1999)
C2500 = “3/4 Ton” (1988-2000)
C3500 = “1 Ton” (1988-2002)
K1500 = “1/2 Ton” (1988-1999)
K2500 = “3/4 Ton” (1988-2000)
K3500 = “1 Ton” (1988-2000)
Chevy R/V Trucks
R-Series Truck = 2 Wheel Drive (1987-1991)
V-Series Truck = 4 Wheel Drive (1987-1991)
R10 = “½ Ton” 2wd (1987-1988)
R20 = “3/4 ton” 2wd (1987-1988)
R30 = “1 Ton” 2wd (1987-1988)
V10 = “½ Ton” 4wd (1987-1988)
V20 = “3/4 ton” 4wd (1987-1988)
V30 = “1 Ton” 4wd (1987-1988)
R1500 = “1/2 Ton” ( Didn’t Exist!?)
R2500 = “3/4 Ton” (1989)
R3500 = “1 Ton” (1989-1991)
V1500 = “1/2 Ton” (Didn’t Exist!?)
V2500 = “3/4 Ton” (1989)
V3500 = “1 Ton” (1988-1991)
Let’s see examples!
Imagine you have a truck with VIN #:
1GCDC14H3G……. = 1986 Chevy C10 (2wd, 1/2 ton)
2GCEK19K0J……. = 1988 Chevy K1500 (4wd, 1/2 ton)
1GCHR33N7J……. = 1988 Chevy R3500 (2wd, 1 ton)
Fun Stuff Right?










I can’t wait for when you do 1980s Toyotas…
Toyota Pickup= 1/4 ton
Toyota Pickup= 1/2 ton
Toyota Pickup= 3/4 ton
Toyota Pickup= 1 ton
Yeah, Toyota trucks will be a bit less complicated. Sadly, the majority of them have already disintegrated back into the earth again. EEEK!
