MYSTERY SOVLVED!!!

2500HD and 3500 torsion key lift mystery solved. GM has 4 different torsion keys. they all have the same casting number:

15530030

each of the keys is indexed differently, have their own part number, and a color code (small paint mark on the bottom of the key). the mark can be seen by looking under the truck, it is on the bottom of the key.

part numbers are:

15592573 GREEN

15592574 WHITE

15603963 ORANGE

15045171 PURPLE

I have a 2500HD with the PURPLE 15045171 keys. Today I looked at a 1500 and it had the GREEN mark. I talked to the part guy and he had one in stock. GREEN mark, part number 15592573.

I had my stock key with me and compared it to the GREEN key.

Guess What!!

The green key was indexed more than the purple, there for if it was installed on a 2500HD, it would provide a lift just like the Hill and Victoria keys. I knew the Victoria key was a GM product with the numbers ground off. The GREEN 1500 key was indexed exactly the same as the Victoria key I had.

Therefore:

Stock 1500 GREEN keys=torsion lift keys for 2500HD and 3500

There might be others that work for the the 1500's so people don't have to buy the fords anymore :thumb: :thumb: :thumb:

good luck

to clarify some things i did some more research:

victoria sells key for both the 1500 (the ford keys) and the 2500, 2500HD, 3500. they keys they sell for the 2500, 2500HD, and 3500 are the gm 1500 keys with the green mark.

I have a 2500HD my keys have the purple mark on them.

I don't know which keys are indexed the most. i was only able to compare the purple keys to the green keys. the green key was the only one the dealer had.

both of my keys are purple. i looked at a 1500 z71 it had green keys both sides. i looked at a 1500 4x4 it had green keys on both sides. i also looked at a new tahoe, it had green keys on both sides.

i am willing to bet the orange and white keys are for the 88-99 old body style 1500 and 2500 trucks.

i hope this clarifies some things
