SC/TURBO axle & spool kit GTS

[WeirPerformance]

Another first brought to you by Weir Performance. We often get asked by customers for a stronger axle shaft for the GTS. We decided to answer the call with our new “SC/TURBO” axle & spool kit. Designed to handle the added power of a super charger or turbo, these axles are 30mm dia. at the spline compared to a kouki axle, which is 25mm. These axles are even larger than the ’79-’81 supra, which are 28mm at the spline. The SC/TURBO axles in combination with our special heavy-duty spool can easily handle up to 350HP! The best part, NO HOUSING MODS REQUIRED and accepts factory brakes!

The axles come fully assembled with new Koyo bearings, new axle retainers, extended wheel studs and axle seals. You will have to install the spool into your third member, then simply replace your O.E.M. shafts with our SC/TURBO axles and re-install your brakes. Keep in mind, this kit is designed for serious racing use only, not intended for daily drivers!

But what with differential? Great idea, but obviousely you have to change the whole unit

[Ivan141]

The spool he is referring to is that black thing in the middle. It is the professional equivalent of a welded diff. (much lighter though).

Is there a possibility of using a LSD with this?

[Project D]

If you can do side gear for TRD, Tomei, Kaaz, etc.. LSD it can be realy cool

[WeirPerformance]

We are working on doing this same upgrade for LSD's. TRD will be the first LSD we will make this fit, Kaaz, Tomei will be next. We will post when it's ready. Thanks,

AWESOME!! Its great o finally see that their is someone out there willing to manufacture upgrades for the relatively "weak-link" in the AE86 running gear. however, the main problem we find on drift cars be it 4ag powered or sr20, s2k etc is not drive shaft problems but Crown wheel and pinion problems?? the pinion bearings cannot handle the power and fail.

I for example cudnt keep gearboxes in my 4ag powered AE86 so now i have upgraded to a W Series supra 5 speed box which is brilliant because i can safely say it will never break within reason. but now i have just pushed the problem further back and its only a matter of time before i start getting final drive issues....ohh and for the record, i have NEVER broken a shaft in my life.

Well, you are right that the AE86 does have a problem within the differential. However, the problem is not the pinion bearings, the problem is the weak factory crush sleeve. We have been replacing the factory crush sleeve for quite some time now, replacing it with our solid spacer and have eliminated this problem completly. We have not a single customer who has failed a ring and pinion since.

One thing to keep in mind, The pinion shaft itself is larger in diameter than the o.e.m. axle shafts, zenki or kouki. The ring and pinion gears multiply the torque being applied by the pinion shaft and send this torque to the axle shafts through the differential or spool. Lets say you have 100 ft. lbs. of torque applied to the pinion gear, multiply this by the gear ratio, say 4.778. You then have 478 ft. lbs. of torque being applied to the axle shaft itself. Way more torque than the pinion shaft, and the axle is smaller in diameter then the pinion shaft. So, you should be breaking axles before ring and pinion gears, period.

Check here for more info on the solid spacer, it sounds like you need one installed in your rear. Keep in mind it does have to be installed correctly in order to work correctly!

I almost forgot to add this. The differential bearings of the 6.7" toyota are the same as the 7.5" chrysler. Also, the GM 8.2" shares all of the same bearings as well, except for the inner pinion which is slightly larger than the 6.7" toyota. Now, here is the shocker, the 9" ford inner pinion bearing is smaller than the inner of the 6.7" toyota, the outer 9" bearing is slightly larger than the 6.7" toyota only because the 9" uses the same bearing inner and outer and the 6.7" has slightly smaller outer. Interesting info I thought people should know.

Excellent idea, but the problem is, that my 5,375 r+p is even weaker than the axle shafts, so i guess i have to cheange to another axle...
