allrigth i broke my axle .

i took it apart today and is the left side axle

the punking and other axle looks good, is there a company that makes them ?



also im gonna post some pics tomorow, im not sure what year rear is it

im thinking gsl-se

is there any other model that came disc brake and posi ?

about the splines are they all the same

 

My 82 has disc brake and posi. Not sure about tthe posi/LSD years. Rear dscs started in 81, and were offered through 85, if I'm not mistaken. I'm not certain which model mine is, GSL I believe, from the options on the car.,,,,BB

 

anybody knows whats the patter for the gsl se ? and the gsl i trying to find out what kind the rear is

 

AFAIK, all '84-85s had the same axle size and splines. Your difference will be the bolt pattern. GSLs had LSD and disc brakes, but came with the 4x110 bolt pattern. GSL-SEs had LSD and discs, but were the only first gen RX-7s with 4x114.3 bolt pattern. The easy way to tell them apart: GSL-SEs have lug nuts, GSLs have lug bolts. I don't think you can get a new axle for a reasonable price from anywhere, however, used axles are easy to find.



If this is a regular occurance for you, consider upgrading to a modded 8.8" out of a Mustang. You'll have to relocate the mounting brackets, and you'll probably want some c-clip eliminators.

 

someone makes axles for those, some domestic company, i forget

 

I can vouch for the 8.8's toughness. I have a few performance mods on my 98 F150 4.6, so it's about 260HP at the flywheel. I have had no problems whatsoever.,,,,HD





A little pricey, but if you keep breaking axles like this it may be a viable option...

 

Well the axles are the weak link of the system, that is for sure. I really hate putting that heavy 8.8" in there.



I have heard quite a few conflicting comments on what the stock rear can take. Some people say that 350rwhp is the limit others say 500. Some people say the break them on a car that runs low 14's other say that it will carry you into the 10's.



All I know is that I have seen people with v8 swaps putting out over 400rwhp and launching on slicks at 2800RPM. I know that this does not really compare to a 6k drop. But I also keep thinking over and over that at the same hp the V8 produces boat loads more torque. And since that is what breaks rear-end components I try and focus on that.



Does anyone know what material the Stock axles are made of. Are there any HD aftermarket options?



Thanks

There is a company that sells a full-floating conversion kit, but I don't remember who. I do know that it's expensive as hell.

 

HAHAHA, yeah "expensive as hell" does not really work with me

 

Call around and find a powertrain company, we have one in my town that will fabricate axles for anything.
