RPM range expected with 4.88 Gears?
Ok, so I searched and searched some more trying to figure out what would be the RPM range with 4.88 gears while doing 65 mph, bu tno luck. The gearing charts I found seems tobe way off or don't really apply to our trucks.

I own a 1997 4Runner SR5 2WD, I just installed new 33x12.5x15 tires on it and still running factory 4.10 gears. Right now with factory gears, the RPM @ 65mph, ranges between 1950 & 2050 RPM. How much higher will the RPM be with 4.88 gears while doing 65mph? Thanks!

Well... i dont know if this will help. but I have a 3.0 with 33s and 4.88s and i run at around 3100 RPMs. itll be different with yours though.

Use this one, it has our Toyota transmissions programed into it (just select your tranny) and it will be right on. http://www.ttora.com/forum/showthread.php?t=56784
