Hi-

Quick look through CMP parts book shows only one ratio for all.

Manual specs show the C30 and C60 series as being 7.16 to 1 while the parts book lists them as 6:43 ratio (same thing).

Though your point is well taken if you could find a pair of ring and pinion gear sets from the heavy civi chevy truck, that used the same differential carrier, you could go to 6:39. This would give you better road speed while slowing down the drive train which would be a good thing for the road. But this option would only work if you were also up engineing as the 216 engine just doesn't have power.

All in all the tire size, gear ratios, and engine size for the CMPs are probably a very good balance for conditions they were design for. The off road performance of CMPs is down right impressive. After 30 years of club trail rides people are still amazed that my HUP will climb anything a Jeep or M151 can climb. CMPs just do it slower.
