Did you buy it new? How do you know it came stock w/ the smaller tires?
Don't trust that page...I myself have found discrepancies with it when verifying gear ratios for friends of mine.
Well, then you're the first for me. Did you buy your 4Runner new? How do you know it came w/ the 225s...just curious?
Sorry, but not a single '01 or '02 4Runner came with 4.30s...4.10 was the tallest ratio offered for these 2 years.
P nut's right. Don't believe the door jam sticker. ScottyC on YT recently purchased a '00 4Runner and the door jam sticker said he had 4.56s! It was not until he pulled the gearing (to install a set of 5.29s) did he discover he really only had 4.30s.
The best way to know EXACTLY what gearing you have is to pull the gears and count the teeth. However, I've never heard of anyone pull their gears just to find out what gearing they have then reinstall them. The next best solution is the tire/driveshaft rotation method:
Jack up your vehicle so 1 rear tire is off the ground. Put your vehicle in neutral. Mark the drivshaft universal with a felt pen or anything really. Put a mark on the lifted wheel at 12 oclock. Rotate the wheel so the driveshaft turns. Count how many revolutions the driveshaft makes by turning the wheel 1 revolution. If you mark your driveshaft so the mark is at 12 oclock and also the tire marked at 12 oclock. You should be able to determine your gear ratio fairly acurately. Example...If your driveshaft rotates just over 4 revolutions per 1 revolution of the wheel. Its 4.10/1.
