8.25 suregrip

Definitely a sure grip but what ratio is it for? Theres two different ones. One for highway type gears and then another for lower gears like you'd see in a street car. Such as 3.55's. I think 2.71 and higher ratios used a different sure grip. Im no expert in Mopar differentials though so maybe one of the residential forum gurus can chime in on the different sure grips.
