I had to sell my last sure grip with my Charger and now need one for the Challenger. I have a 2.76 open (489) for now, but i need the sure grip. I have never seen a 2.76 sure grip in this case/pinion size, only 741. Did they not make them or did they just all get gear-swapped for better gears..??? Also, were there ever any aftermarket gear sets with higher gears for the 8 3/4"...??? I mean 2.5's or ???

Sorry Doc,,, my edumacachun learnd me that a 2.41 is a tall gear as in hi speed on the highway a 3.91 is a low gear,, good drag gear for quick acceleration .. in other words a 2.41 is a horrible drag race gear but is great for cruising a 3.91 is a good drag race gear but not highway friendly.. I am truckless..

You are the only one that I have ever heard refer to gears this way. Short, low, digger, deep gears = 3.91 and numerically higher. Tall, long, highway, freeway gears = 2.76, 2.93 etc.

Not that this will change the Doc's mind. I think he just does it to As to the OP, my 66 New Yorker came with a 2.76 SG but it was a 741 case. Kevin

Its not that I want to call it one way or the other,its the right way to describe it. Tought to me by mechanics,racers,shop teacher,and others. Guess we are all wrong,you are the first person I have ever seen describe them that way. 87 D100 225 4 speed.

WHICH # is more numerically bigger, larger .... aka taller ? Now if you want to "corrupt" that reasoning to mean the opposite .... lite-up another I know what you are trying to say ... I have been dealing with this MORE TIMES than just here .... BUT THIS is just like what they do to us in the voting-booth sometimes ... they have us voting YES on a ballot ... if we don't want it to pass. ...
