I appreciate the feedback. I think the best approach is for me to first identify what is in there now, and then find the next higher pinion size, 1-2 tooth higher, and try that. I have two electronic speed readout signs that I regularly cruise by to use as a reference.

The standard 18 tooth red gear had the speedo reading high, I was actually going 55 and speedo showed 62. Put in the black, 19 tooth gear and all is well, I only show 2mph higher than actual now. Good luck finding these gears, CI torqueflight specific and they are scarce.

My RAM Charger is on it's third speedometer and reads about 10 mph slow at 55. I'm sure that somewhere I got the wrong cable or gear or something, but for pushing snow it works.

 I'm trying to determine the proper speedometer pinion gear for my 300G. My speedo reads lower than it should and I'd like to see if I can improve its accuracy, at 40 mph I'm actually doing about 45. I'm running 235/75R15 tires and a 2.93 rear axle. Any suggestions on the proper gear? I know they come in different colors to differentiate different ratios.  Thanks!  Bob J  __._,_.___ Posted by: "Bob Jasinski" <rpjasin@xxxxxxxxxxx> To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to bob@xxxxxxxxxxxxx or go to https://groups.yahoo.com/neo/groups/all/manage/edit For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/search.htm#querylang __,_._,___ |
