Default For all you high HP guy's

I am building my car right now and am contemplating replacing my stock rear axle/hub with an aftermarket "high horsepower" Rear Axle/Hub. My question is should i do it, how many people have done it, and at what HP are people braking the CV joints or axles. Is it worth it for me to do now or wait till something happens to do anything about it

Thanks guy's

The CV Joint and Rear Hub are the LAST of your increased HP/TQ issues.

If you address the diff short shaft problem, OEM clutch and thorw out bearing issues,, you will be HEAD and SHOULDERS above the HP curve....

Up grade your CLUTCH ,,Torque Tube bushings and Differential output shafts add a clutch bleed system and you will be bullet proof to 700 HP.

Tust me.

Thanks for the reply I guess I should say I have and RPM 6 speed tranny and a DTE stage 4 rear end with a DTE Differential Strut Kit as well as a carbon fIber drive shaft and a twin disc clutch good for 1000hp but my goal for the car is around 800-900hp. What does the bleed do and any suggestions on the shot shafts.

If your clutch fluid is contaminated with sub par clutch fluid,,,,,,,,,,,,,,,, your shifts will always be compromised.. Change /bleed out all the old fluid and see if the shifts improve.

Also,,,insure that your clutch is fully disengaging. Put the tranny in first and Rev the engine to 5000 rpm. If the car moves, the clutch is NOT fully disengaged and that will effect normal shifting.

I'm still running stock Z06 Rear Axle/Hub, and it's holding up fine. I'd save the money till you break one, which will be pretty hard to do. I imagine it will require a pretty violent launch and really big sticky tire such as 28" slick. The kinda launch tirecraft is very familiar with, putting down some big torque with N2O.

The remote bleeder helps keep your clutch hydraulics in good working order. On mine, I just upgraded the driver side diff output shaft to hardened from DTE since I see people breaking those alot. So far mine is held up, but when my diff let go last year, the hardened shaft showed stress, with the splines layed over and some twisting.
