it would take a 225/40-17 to achieve a 24.1" diameter vs the OE 25.9" dia.

Just did a quick search and didn't turn up anything so....

Is there any way to recalibrate the speedometer for use with a different final drive?

I dont think the speedo should be off, I believe the 8's VSS is in the tranny, not the diff.

Someone correct me if im wrong.

I know there are boxes that you put in line with your speedometer that let you recalibrate it. I read threads about them here quite a while ago. Don't remember what they are called.

no what is in ur wheels is the wheel speed sensors which are for abs as well as for traction control............the vss which is the vehicle speed sensor is calibrated through a sensor usually on imports n domestics is on the back of the transmission not on the rear end.............just thought id put my $ 0.02 in............but how much did it cost for rear end gear swap n lsd conversion........thats my next mod in mind.........i have rb intake rb exhaust B&B midpipe upgraded plug wires, flywheel clutch rims rb raceflash n a hooked up system......i want somethin with a little more of a gain in the accleration which i can give up 10-20 mph top speed to break in 13's...... so can u give me an idea how much it ran u for parts, i got a guy at my work whos our shop mechanic that can do the install.......i just gotta get a price n location where to go

I ordered the gear from JonDemand for around 700, maybe a little less. Paul at Mazmart is having the new diff built for 300 plus a 500 core swap deposit. Not sure if these prices are still good or not since I ordered mine back in January. Hopefully will have it installed by mid May.

so did you need anything else other than the gear set itself in order to get the gears installed?

You'll need a new bearing for the pinion (it's pressed on).
I think you can reuse most everything else if its all in good shape.

correct . Changing the final drive will not alter speedo readings .
Only way you can stuff up your speedo is with different sized wheels.

Hmm, you are getting similar MPG for before and after, thanks for the updates! Additionaly, your after MPG is better than my current MPG (~ 17) with stock. If this is case, that MPG isn't significantly affected, then I too may consider this.

Thanks again, and please do continue to update your MPG at your leisure.

Goodbye!
