Derek,
I try to keep records, but I can't be 100% sure I didn't miss noting a gear change. The last one I have noted was at the start of the 2010 season. I can't swear that I hadn't changed them since then, but even if I did, I'm sure it wasn't more than once. I easily do over 100 runs per season and I have gone at least 2-3 seasons without a problem. Last set was changed due to wear rather than cracks. I need to check the current set before next season. Most runs are 1/8 mile, IHRA allows the Mopar aluminum centers and I run Amsoil synthetic lube. Car weighs 3,530+ or 3,700+, 1.47 - 1.52 60' times footbraking with a 360. 11.20's to 11.50's. But even with OEM centers and untreated gears, I've gotten at least couple of seasons out of them. Have you tried anyone else for gear set-ups? Your car is probably heavier, which doesn't help. But I honestly can't remember if or when I may have wiped the whole gear. A while back I had a howling rear and found 3 teeth gone and 3-4 chipped and/or cracked. That was before I started getting them treated.
