Re: Gear Ratio ???
For 81, The 6 cylinders got 2.73 as std axle ratio. GQ1
The 8's got 2.56 GQ1 Unless it's a california truck; In that case 6 cylinders got 3.08 as the std axle ratio code GQ1 and 8's got 2.73. i went thru this dilema yrs ago when i first got my truck. Also, if you bring your vin# to any decent gm dealer they can type it in and tell you exactly what gear ratio came with the truck originally. Last edited by C-10 simplex; 12-29-2010 at 06:34 PM. |
