RE: [Chrysler300] 300 F axle ratios.

["'John Grady' jkg@xxxxxxxxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Hi Noel, thank you,

 

Mystery grows a bit as it  appears 3.23 was used on G , per JY (to comp tire size change? ) ,( and was on an independent  list of widespread use of 8 3/4 gear ratios, nothing to do with 300’s) and here we have from Noel 3.15,as opposed to 3.18. Going to count our gear teeth,  but it is stamped 3.18 on the gear , and outside. That 3rd party list had neither  a 3;15 or 3;18 , but may not be all inclusive..although presented as if it was.

 

Also found out early 57-late 60’s dana clutch type bolted together sure grip is the best one, later one  with cones,  more for snow traction, not “racing”. Same place claims all this interchanges into center section with its own set of carrier bearings, for each type of sure grip. . At this point , adding sure grip probably not high on any list, but they mention Auburn gear as a dana type bolt together sure grip for 8 ¾ , also serviceable, but 30% more torque. All by way of trivial pursuit?  Pinion bearing , stem and U joint got bigger over the years, too. 

 

Thinking of putting what we have back in. But I had 3.54 in a dodge in 1960 new, liked that. 0-100 matters more than 135 mph? Gas impact probably minimal….

Good Morning,

My research for Macungie came up with 4 F axle ratios - 2.93; 3.15; 3.54, and 3.73 - on addition to the most common 3.31.

JY and i got into pumpkin on F convert we are doing , it has 3.18 ratio ? I believe they were factory 3:31 ? I know earlier 300's had many optional ratios , but not sure of F ? 
We are awaiting data plate decode from Gil , have not heard from him in a while . Hope all is ok with him down there ? 
In the interim -- Anyone know about axle ratio options ? 3:18 seems too close to 3:31 to be worth doing ? A replacement ?
Also sure grip was stand alone option ?
