Re: [Chrysler300] Speedometer pinion gear for 300G

["2HsandaHeritage@xxxxxxxxxxx [Chrysler300]" <Chrysler300-noreply@xxxxxxxxxxxxxxx>]

Hi Bob,

I am going thru the same problems with both of my 62's.

My Sport Conv has 235/75R15's and a 323. The speedometer and odometer were reading much higher than actual by about 10%.

I replaced the 19 tooth gear with a 20 tooth gear and cut the error down to about 5%. I need a 21 tooth gear but have not been able to find one.

My 300H also has 235/75R15's and a 323 and has the same problem as your G. It has a 19 tooth gear and I have an 18 tooth gear that I haven't installed yet.

I use two different aps on my cell phone to check the accuracy and also use mile post markers on the freeway to confirm what the aps tell me.

Jeff Carter has the gears - if you are off 10% you may need to drop by 2 teeth - one for every 5%.

Hope this helps,

Doug Warrener

Subject: [Chrysler300] Speedometer pinion gear for 300G

 

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
