I was doing some searching to find out if my 1500 keys will level my buddies GMT800 2500 non HD and found the indexing degree by the color.
Fullsize trucks use 1.75" hex and S trucks use 1.5" hex so the keys are not interchangeable
15045171...4 degrees...Purple (stock 2500HD)
15657374...9 degrees...Blue (FK2 S10)
15603963...12 degrees...Orange (also S10)
15592573...14 degrees...Green (stock 1500)
15592574...18 degrees....White (Z85 suspension S10)
There is also a yellow key for the S trucks but I do not know the degree of index
I will update this and compare OBS 1500 keys to NBS 1500 and 2500 non HD keys all side by side and if I find anymore info about the different keys. If anyone else has anymore info feel free to add.
