Is the a real difference in diameter? I understand more splines is more surface area. And if they have added splines doesn't that make the star thinner? I also know some axles taper so that the axle is smaller than the spline area. Is this the case with 35 spline?

I'm trying to decide if I need the bigger set up. My car is 3200# maybe 800 wheel and 35.5 tire, midboard hub

Thanks Jeff
 
are you currently having axle or CV issues w/ the 33 splines?

35 is supposed to be stronger... had a friend that was going through CV's w/ 33 splines, he has swapped to 35 spline and so far so good after about 1 season. But this is through a 2 seat TRX w/ close to 2k HP and someone who runs it very hard.

Its a new build . Thanks for the input
 
Yes, 35 spline is a slightly larger pitch diameter and OD. Yes, cv star gets ever so slightly thinner (have yet to see or hear this being an issue).

If its a new build go 35 spline and be done.

The biggest downside is spares. It is easier to find a 33 spline 934 cv when you are in glamis.

Yep. CV is natively 33spl. A 35spl 934 is machined to accommodate a 35spl axle, and not all manufacturers are equal when it comes to approach.

For new build definitely go 35 spline up front. Just make sure to carry a spare CV and maybe 1 axle as they are harder to find when you’re in a pinch for time. Hopefully you’ll never need the spares but nice to have.
 
It all depends on what you are breaking, 35 spline make the axle stronger but the star weaker,

Info on said build?
Start a thread....we all love reading about sandcar builds.

Yeah I agree Jeff. Get some pics up on how that build is going. Been a minute since seeing it in your garage.
