Finally decided to upgrade axles and driveshaft before I snap another one. Undecided on which one.What are the pros and cons to having a cv joint on the driveshaft.? ..Im at 494/478 launching on 18" Nitto 555R

I presume you’re talking high speed, Rzeppa CV type joints for the ‘driveshaft.’ Typically, these are better suited for lower angle/RPM applications. You do see them in lower angle, rear wheel drive drivelines (like a Jeep JK) but they seem to have a finite life on the main driveline. If spec’d properly for axle shafts, they’re awesome, due mainly to the lower rpm nature of an axle.

In a stock Camaro, there is very little driveline angle but the higher rpm and torque make it better suited for the OE flex disks or cardan style u-joints than a 6-ball CV. So I don’t really see any adavatages for a CV at all in a Camaro given the relative low angles. CV’s were developed to eliminate the tortional vibrations associated with single u joints through an angle. It’s why the OE flex disks work well - low angles.

For higher HP cars, some shops have made aluminum shafts in 1350 series with single cardan style u-joints with good success. I’m told though that given the need for flex disk adapters on each end, (to mount standard flange yokes to the existing trans and diff disk flange) there is no significant weight advantage to this style shaft when all is said and done. But it is beefier and can handle upwards of 700-800 HP fairly easily.

My car is at 430rwhp with heavy Hurst Stunners and lowered 2" so I'm putting a lot of torsional and angular stress on the 1200hp G-force axles without issue. The stock axles would snap as soon as you tried to launch it.

Stronger axles are essential with modded 5th Gens. It seems like the order of failures is axles, differential then, well, never heard of a stock driveshaft breaking. But, then again, I think folks swap it out with the other changes (axles and diff).

Whether Geforce or DSS, both are quality, and both back there products.

5k plus launch, mod's in sig, hop breaks axles...
