what engine and tranny do you have?ddriggers2 said:Guys, I got a link to here from this board to try and pick out what gears I need. I don't wheel much, but I do want the stock power back after putting on 33's. I have a 98 pre-runner with non-TRD axle.
I am not very mechanically inclined when it comes to taking apart a rearend, so I will likely have a shop do the work.
My question is, which gears do I need to reclaim my lost power, and do I need the master rebuild kit as well? There are 2 different sets of each ratio listed...what is the difference and which would you all recommend?
Also, when I change the gears, will my RPM's go up or down when on the highway? I run close to 3200 right now @70MPH, and I would like it to be less for some better MPG's.
Thanks,
Danny

what do you mean different part #s? you either have TRD e-locker rearend or you don't. that will be the only difference. don't bother ordering off their site, call and speek to Alex.ddriggers2 said:
what tranny do you have? If you have the AT you could go with 4.88s and be fine as long as you don't plan on crusing at 80 mph all day long
with the manual I wouldn't bother with 4.88s for 33" tires on the v6. your rpms will be too high at hwy speed and your gas mileage will actually go down.
Nevermind, I actually took more than a minute to try and figure it out. One set is for the front diff, and the other is for the rear.hytenor said:what do you mean different part #s? you either have TRD e-locker rearend or you don't. that will be the only difference. don't bother ordering off their site, call and speek to Alex.

4.56's I guess it will be.
Thanks for all the help.

with your prerunner that will be the best gearing for your 33sddriggers2 said:
you'll wind up with a little better power than stock with 31s and better gas mileage.
If you want to get right back to as close to stock as possible you can go with 4.30s which will give you an 'adjusted' ratio of 4.04:1 with 33s. I would still go with 4.56s for a 4.28 ratio for slightly better power to pull the larger tires. Gas mileage with the 4.56s should be a lettle better than stock with 31s even with your 5-sp.boogyman said:
for example: your rpms now, running 4.10s/31, should be about 2800 at 75. With 4.56s/33s the same speed should give you just over 2900. (figures assuming actual tire diameter). this will give you better off the line power as well as making it easier the engine to maintain speed on hills in the higher gears. this will also make your clutch happier
with the 5-sp and 4.10s you can 'survive', however, w/o regearing. you'll notice a power and mileage drop but it won't be that bad.
stick with the 4.56s for your setup. even if you go to 35s you will be set with that SCBajaRnr12 said:
4.88s/33s and the v6 5-sp is just too low-geared IMO, especially for hwy driving. If all you did was wheel it would be different but I doubt you plan on trailering your Taco
Awesome, thanks. Hey do I really need the install kit or can I just swap the r&p and leave all the original gaskets and seals and crap? And is it really that tough to install? I'm pretty mechanically inclined but if it's gonna be a bitch or if I'm gonna destroy my truck then ya I'll definitely have a shop do it.hytenor said:stick with the 4.56s for your setup. even if you go to 35s you will be set with that SC
