Anyone make lower gears for R-cut Dana 60s?

I am trying to find out if anyone makes lower gears (higher numerically) than 5.13s for reverse-cut Dana 60s. So far the only info I have is from Reider Racing, and that's as low as they go. Any leads on lower gear ratios would be much appreciated!

Thanks,

I wouldn't swear to it but I think you can get RC 5.38's for the 60. Call R&P at 503-557-8911 and talk to Rich Imholt. We just put in 4.88's and I think the paperwork had a listing of the newest ratios available. Be aware that these gears were for the late model with a crush sleeve(collapsible spacer) but no reason a good machinist couldn't make a solid spacer to work with shims like a standard early model 60 like they do with 8 3/4" Chryslers and 9" Fords. Good luck. Nickmil.
