Teraflex did me a solid
I dusted a stock output on my dana 300 and wiped out 3 of the 5 4:1 gears at the same time. Had the gears a long time and just about everything about my rig voids any warranty, and they have been beat on. I called teraflex customer service looking to purchase new gears but instead got the 3 shipped to my door for free within 3 days no questions asked. Hard to beat that kind of service.
