Re: Anybody got a set of gears for an 8.8?
Hmm, if u have the mazda 5 spd, your OD would be .8, mine is .71, so u might have the 273s. If you had the zf it would have granny 1st adn reverse.
Use 4th (direct) gear, and check rpms, this will make it constant insted of havig different OD ratios.
If your truck came with 235s stock, at 2K with 273s in 4th gear it shoud go about 62
If it has 308s @ 2k it should run about 55
