RCV offers a true full float rear axle shaft for the FZJ80 that is made of 4340 and has the standard 30 spline count andd 100% USA made according to RCV.
Just the other day I saw that Nitro is offering the same sort of two piece full floating rear axle shaft in 32 spline but it’s made of 4140 and in where/who makes it I don’t know.
Search results have numerous sources concurring on the superiority of 4340 ultimate strength in a shaft application. But we also praise spline count and in order to run the Nitro shafts a swap to the 100 or 200 series third member set up is required and that design also offers enhancements of its own besides the increased spine count.
My question here has only to do with which shaft should be viewed as superior: 32 spline 4140 or 30 spline 4340 assuming all else equal.
