Gear Vendors or swap to better tranny?

i know three guys running the GV OD units and they love them.. turns their 3.55 gears into a 2.76 ish gear. two guys with challengers it went right in no issues. the one challenger owner has to have 50,000 miles on that thing and its been flawless. the third guy has a dart and only needed to dimple the floor in one spot. not cutting of anything.

hell it seemed like most of the cars in drag week were running them also..

only thing i wish is that they would make an option for a better OD ratio.
