get up to highway speeds???

[Combat Chuck]

The original factory tires were likely something like 28" to 29". Going to 35" tires only adds 4" to 3.5" lift respectively.

Thanks for the info. that's why i love this forum, learn something new every time I log on.

Another tid-bit...

According to Stacy David, for each inch you go up in diameter you take .10th out of the gear ratio.

That leaves you with your theoretical gear ratio.

Now it way get more scientific than that, or I might not have the right term for the gear you have, or you might want to argue about it all day...

But you'll be arguing alone. I just use that b/c it's the quickest way "off the cuff" to find out what rubber ratio you really have.

.10th per 1"

Or you could do it like this.
4.10 (factory ratio) / 28.5 (factory tire) = .14
4.10/35 = .11
While 5.29/35 = .15 (More power!)
Or 4.88/35 = .139 rounds to .14

So, using a 4.88 diff ratio with a 35" tire will allow you to hold a accurate speedo and have a small loss of power due to difference in tire weight.
While using 5.29 diffs will allow a small increase in 'power' and compensate for teh difference in tire weight.

just my .02
