im going from a 2.73 peg leg to a 3.23 limited slip, i know the speedo will be off, so how do i fix this?

 

the easiest way is to just post your rear tire size and I'll post what you need.

 

16 245 50

 

grey speedo gear?

edit: nevermind your talking 3.23 i think grey is for 3.73. dont listen to me.

 

You have 2 choices: (1) a gray 15 tooth drive gear, GM part number 8642620, and a blue 38 tooth driven gear, part number 25513045, or (2) a red 17 tooth drive gear, 8640517, with a purple 43 tooth driven gear, 25513050. You won't need to buy anything else to get the speedometer correct.

 

that was pretty fast atilla. is there a place to look because i have the same 3.72 stock but i went to 275/60 15 tires. i know 60 spedo is 65 actual but it would be good to have it right.

 

I'm working with a moderator on getting all this info I have, made into a sticky, on 700R-4 speedometer gears. But until then, What I need to know is rear tire size and rear axle ratio. In Tony's case, 3.72:1 gears don't exist, so he must have mis-typed.

 

whats the difference between them, is this stuff exspencive?

 

I believe he meant 3.27 as he typed in first thread.

 

They aren't that expensive. Few bucks, maybe 15-20 if I recall when I got mine. I ordered mine through NAPA so they are easy to get as well. Maybe check NAPAs website for prices.
