3.73 is standard on that truck, I believe. Eazy to find out which yours came with.. Check your axle code
I'm not a mechanic, does this require me crawling under the truck and finding a stamp? I can do it but I posted here hoping not to. Thanks.
There will be an RPO code on the "service parts identification" label on the door posr or glove box. The F, G, or H codes identify the axle.
GQ1 -- AXLE REAR, STD RATIO GT4 -- AXLE REAR, 3.73 RATIO GT5 -- AXLE REAR, 4.10 RATIO GU4 -- AXLE REAR, 3.08 RATIO GU5 -- AXLE REAR, 3.23 RATIO GU6 -- AXLE REAR, 3.42 RATIO G80 -- AXLE REAR, LIMITED SLIP (POSITRACTION)
HC4 -- AXLE REAR, 4.56 RATIO
That code list tells you what colour, what wheels, what GVW, all the different options on your vehicle.
Thanks. The glove box had a bunch of groups of 3 numbers and letters, mostly faded, but one did show GT4.
