Default Normal driving or Hard driving??

StreetSnake For what you save in weight is not worth the safety in time. ERA has a steel shaft and in 12 years no problem with 95% racing. I have seen aluminum ones shatter. GM only uses them on some truck where they can have a 5-6" diameter shaft fit. The most important thing is, have the correct angles between the trans and the rearend. You need this to off set each other to remove vibration in the drive train line. I think NASCAR uses them and then throughs them out after a couple of races. I think welding steel to steel is a stronger connection than tig welding aluminum to aluminum. If you have room, have 2 drive shaft loops installed in the car for added safety. Have a 1" clearance from top to shaft and 1" side to side. ERA has used steel shafts for over 30 years. I think if the aluminum was 100% safe they would switch or give a choice. Rick L
