I have a 2002 s10 with 24" lift. it has the 4.3L vortec and an auto 4L60 trans. im runnin 39.5's with 5.29 gears on toyota axles. ive noticed the truck doesnt like goin 60. should i waste my time and try 5.71 gears instead? any help would be nice. thanks

 

Take about 20" of lift off.

 

V6 chunks, Longfields and 5:71's FWIW....


I have a 1984 toy truck, I was running a 350 .60 over sbc last year and the front end held togather. Now going with a 400sbc. The motor builder says 600hp. How long will the front end hold up? Will longfields hold up? Will the rear hold up to?

 

That does not look like a toyota. I agree take some lift.

 

kinda hard for him to take out lift with that link setup he's got.

 

i wouldnt suggest 5.71s. I had a set on an old toy i had on 44s and i couldnt keep a pinion in it because theres only one tooth at a time on the pinion grabbing the ring gear which makes it really weak.

 

What diff did you have? IFS, 4 or V6?

 

You don't have Toyota trans gearing, but have a 200hp V6, and it doesn't like 60?

"Power output of the new LU3/LG3 engines is 180 hp (130 kW) to 200 hp (150 kW) and 245 lb·ft (332 N·m) to 260 lb·ft (353 N·m)."


Is it over revving? Revs too low?

 

couldn't ya run some different coil-overs? to lose a little lift i mean...not suggesting it...just asking

i've heard that 5.71's aren't any weaker than 5.29's...

 

Well you've already wasted tons of money. Might as well give the 5.71's a try.

 

I was joking. That big of a lift makes those tires look small.

 

5.71's are weak and youll break them if you wheel it. the pinion gear is just too small.

 

do your research...lots of people wheel on 5.71's.


if you're not sure, then have them chryo'd

 

ARE 571 GEARS REALLY THAT WEAK?



Again, for what diff? The 7.5... The 4cyl, or the V6...?

 

^^ zuk is the master..

@87yota, if you break the pinion and not the ring, more than likely something is setup wrong. the ring gear has the smaller/weaker teeth. a proper setup up is where you get your durability.

 

or not knowing how to use the skinny pedal correctly.

 

meh, thats helps too. although a good install and quality gears will take hundreds of revlimiter clutch dumps with no probs. ask me how i know

 

yes they are that weak, you only have one tooth on the oinion engaging the ring gear at a time compared 2-3 from the 4.10, so even though the teeth are a little beefier, it doesnt matter if it can only grab one at a time, ive seen plenty break my buddies broke 3 sets then went back to 5.29 and stopped breaking them.

 

D60 with 5.13's

 

You know that was a link, don't you?



IIRC, the lowest a set of 60's can get is @ 7:?? something

That's Portal axle low, w/o the portal though...
