[QUOTE="POR, post: 741923, member: 8169"] But as the gear ratio goes lower it gains more leverage to spin, which lowers the working stress on the pinion teeth. Most of the old SN Fab cars ran 6.17's and still do to this day. One of the guys in our group runs a pretty healthy motor on 6.17's and they've been holding up for years. Ive always felt heat more than anything killed the pinions. 5.13's and 5.38's are a very good all around working low gear. They still give ya ample wheel speed when needed. I'd run 5.13's if it were me lol [/QUOTE]
