gears/tires speedo correction

I'm on 33s, with factory 4.10s, getting ready to bump up to 4.88s ... What do I do to correct the speedo?

I would say programmer as you can correct tire size, I think you can compensate for gears as well.

shouldnt it be pretty accurate since now youve bumped both the gears and tires?

if you do get the gears let me know about your 410's

You don't want the old ring/pinion... its toasted from when it ran dry. Been humming and whining since then, doubt you want wore out gears...

I'm still trying to figure out if its going to offset tires vs gears, or make it worse...

tires and gears wont correct. Youll need a correction device if you truly want to be on.

most likely closer. 4.56s will be the closest to stock speedo, but its not gonna be real noticeable difference from 4.10s t 4.88s. bviously it will be faster versus slower, but still.


Im not gonna do the math, but you can calculate the "difference" pretty easily. Im just lazy.

theres a gear to tires calculator machine runnin around somewhere on the net as well...

for me to get back to exactly stock gearing, I need 4.83 which rounds to 88s pretty closely. I think I'll just gear it and see what happens. Thanks for the input...

heres another quote from this thread
" I replaced my pinion seal 12k miles ago.. with an impact, without a new crush sleeve, and its yet to whine, break, snap, wear, leak, etc."



anyway back on track

4.88's with 33's should get the speedo pretty close , with the 33's your speedo is probley 5-7 MPH slow, 4.88's "should" correct it, it may however make it fast by 1 or 2 MPH. somewhere on a site was a gear/speedo/tire chart.

Hahaha, whine snap or break any worse than the gears were. It has had a howl, since it went dry on a limp home trip 8 months ago, I'm just ready to regear. Still drives fine...
