6 Speed

2500 rpm at 85mph... we have some roads here in Texas with 85mph speed limits. This ain't Oregon. I'm still debating if I run 3.54 gearing 3.73, or 3.90.

Depending on your 6th. speed ratio and rear tire size it looks like a 3:91 would be spot on. Here's a link to the handy calculator. Transmission Ratio RPM Calculator | Spicer Parts
