They guarantee their work for life, so I went with them.

I keep hearing that the new gears bring you back to stock but everyone goes for 4.56 gears. When I run the numbers through various calculators out the if you have 3.73 with 35 inch tires figuring the original was 31 inch tires. The new gears should be 4.21 to bring one back to stock. So there is nothing between 4.56 and 4.21? No 4.30 or 4.33, available? Just curious beacuase I am also considering gears for my truck in about 6 months.
I think 4.56 is perfect, only because it gave my truck a little more torque than stock and kept my mpg's stock. I do mostly highway driving, and I only run about 2200 rpms at 75mph.

You can get 4.30 for the rear differential, but they don't offer that ratio for the reverse rotation 8.8 diff in the front. So if you are 4x2 you can use 4.30, but if you are 4x4 I believe you have to go with 4.11 or 4.56 ratios.
