The ZZPerformance Turbine Shaft is available in a 4340 and 300M. The 300m is rated up to 1000HP and the 4340 up to 600HP. The 4340 shaft is more than adequate for all M90 applications and most others as well. Final grinding on both shafts is done after hardening to prevent inconsistencies.

Improvements Include:

Radius'd o-ring groove
Shaft thickness has been increased in areas of weakness
Gear play on both sides of the shaft has been reduced
Center ring groove has been improved
Brand new diverter tube
No core charge
4340 is more than double the strength of stock and will handle more HP than can be achieved with a supercharged car
300M shaft is over 3 times the strength of stock and recommend for turbo builds over 500WHP

ZZP input shafts are guaranteed against defects in material and workmanship. They are not guaranteed against breakage because we cannot control their use in your vehicle.

So far so good.

Machine and finish quality is as good as a OEM part. Significantly thicker than stock. I just finished building the transmission and just got it back in my car so I've been gentle with break in but have started getting a little heavier on the throttle last couple days. (2006 impala SS v8) 370 whp, twists stock input shafts like nothing on the 1-2 shift. So I hope this holds up.

Racing turbine shaft upgrade

Wow, this is a heavy duty shaft. It is machined just like the oem shaft and fits just fine. I can run much more horse power now . I like it and would buy again. Also was a low price .

4340 input shaft

Great price and quality looks excellent. Fitment is perfect also. I haven't put any serious power to it yet, but I'm confident I won't have any problems at all.
