Installing a 6 Speed Allison behind a 12v Cummins

Looks like GPZ material to me as well, not Alto G3. But the GPZ material is very good, as far as I know you can't get the solid c3/c4 frictions direct from Raybestos? Used to be Suncoast only. I'd change out the slotted frictions in the c3 pack too if you're going solid in the c4.

They are Alto G3B (c2) and G3C (c3/c4)

Can anyone confirm what brand of clutches these are? They came in Alto boxes labeled G3. This is a photo of the C2 and C4 clutches. The C3 are the slotted GPZs, and the C1 are G3s

Can you post a pic of the C1?

I agree, from the image it looks like they're all new style Alto's for C2/C3/C4.
