well it looks like i'm going to put a 302 in my truck and i just got a good deal on 38" tsl sx's. i'm a little worried about breaking the axle. the motor will be between 250 and 300 horse and i'm not scared of the skinny pedal. thats why i'm here, is any one running some thing close to what i will be? have you had any problems? my axle has 4.88 gears and a powertrax locker. i would like to stick with the toy but, i'm thinking about going to a 14 bolt or a 60. if i stay with the toy i will buy a full spool and a solid pinion spacer but, i'm not convinced it will hold the power and the big tires. any info would be great. thanks oke:

They sell chromoly axles for the toyota rear. I think you can get them from marlincrawler. What are you doing with your front axle? That's where the trouble usually is.

the frunt is a waggy dana 44. i'm going to keep open until i can get chromo shafts for it.

Just my $.02, but I'd rather have a Toy front with longs than a Waggy D44 with chromo shafts.

thats great it really is but, thats not the axle in question so, you can keep your change.

It wasn't meant to be a bash, he was just saying that a toyota axle with longfields is stronger than the 44 with chromos. You have what you have and are going to do what you're going to do. However, I think the best thing you can do with a toyota rear is to run chromo shafts. I don't remember seeing specs. I would look at pirate4x4 to see what they are running in formula toys or similar rigs, I just wouldn't post there.

I'm running 4.88s and a 86 rear diff behind a 7mgte turbo out of a supra in my 92 4runner.. at 12psi of boost its about 250hp at the wheels... I am far from gental to her... she hasn't let me down ever.

Chromo axles and your golden... the stock Toyota 8" is the next best thing to a $2k 9"

After having long discussions with many folks, most people don't even run the chrome moly rear shafts, until they really start breaking shafts. The stock toy rear shafts are quite strong. The alloy shafts only gain about 10% in strength over the stock pieces.

Toyota rear axle shafts are the same diameter as a ford 9. You shoudnt really have problems. If you end up breaking a shaft then get chromly shafts. If you break a ring and pinion buy a new set and send them out to be hardened.

They are very strong axles to begin with and you can make them even stronger with just a few things.

I ran 38's for the longest time and never broke one. Now i am running 37's that are 30 pounds heavier then the 38's and still havnt broke one. Now ive got about a 400hp 350 in it with a 700r4. That combo and 5.29's is pretty low and i still have a stock 8in rear end except gears (that are bad-need to be redone) and dont really plan on breaking it. Going to go though and do it later.
Youll be good with that set up. My .02 cents and experince.
