Solution found for weak link which breaks the torque tubes.
Through our years of testing we have found the the factory torque tube rubber bushing can only take so much before she fails. The constant abuse she takes causes it to break apart which then breaks the driveshaft in two. We have since designed a high grade aluminum bushing to withstand the the power being brought to it.
A must when drag or road racing.

Just curious, but by adding a solid aluminum piece, instead of that rubber one Chevy uses, wouldn't it cause some sort of vibration or clatter?

Re: Solution found for weak link which breaks the torque tubes. (Gus)
You would only replace the rear one and keep the front in rubber. By having both ends of the driveshaft with rubber bushings you lose the strength and stability of the shaft under load. By removing and installing our aluminum bushing one the rear end the strength is increased. Almost all the world challange racers use them.

Ernie, why not make em out of Urethane? Or repalce the remaining end with Urethane?
I bet MellowYellow will be call you soon..... :D

I not bashing you, but I know the engineers used rubber for a reason. It may have just been to absorb vibration, but but it might reduce shock loads on other parts. Have your engineers looked at this aspect of changing this part? I guess if the world challenge racers havent had any other parts fail its probably okay. :cheers:

Re: Solution found for weak link which breaks the torque tubes. (rrobert22)
the deal is, though.... if you are running a lot of power and are breaking drive shafts... then you do need to vary from what the original engineers came up with.
Apparently this is already race proven as others have been using the aluminum bushing.
A straignt shaft has a lot of torsional strength. But change its axis of rotation any, even a minute amount... and it's strength decreases exponentially.
I am curious though if any other material was experimented with and what their failures may have been?

You would need to remove the torque tube by removing the rearend. Once the torque tube is out it would take about 2 hours to remove and replace the bushing.

You still use the front one to absorb vibration.
