In my 85 Mustang Stocker, I use street gears in the 8.8 rearend, as I am unaware of any Pro gear availability for this rearend. I tore up most of the pinion teeth of my 5.13`s in about 150 passes, although my current clutch is a bit too aggresive, and has a steel flywheel. Higher ratios with more pinion teeth seem to hold up a fair bit better.
By comparision, my Fairmont bracket car has a Dana 60 with Pro gears, after 8 seasons running low 10`s @132mph (1.29 60 foot best), the old gears still look great, and were changed only for a ratio change. The Fairmont also has a Jerico , with a Soft Lok and aluminum flywheel.
