Sven Made Driveshafts

[angstorms]

I found this over on Facebook this is some very nice engineering and machining on this drive shaft. Our friends in Europe have nice path forward for lifted truck. Hopefully we get Tom Wood looking athletic grenadier soon here in the states. https://4xshaft.com/?gad_source=1&g..._iAnaVmgIBQmyANZqfq2rZTHHmo8LTzQaAvczEALw_wcB.

"direct bolt on double UJ propshaft , accept any lift without vibs .
40 degrees of articulation ( 22 for original )
Fell free to contact me by DM or sventhenat@gmail.com"

Very nicely made without adapters! I would expect Tom Woods or similar to make one soon but with adapters.

@Sven is on the forum as well

It good to recognize all the great creators helping to make this truck even better.

This shaft combined with the new Metalcloak adjustable front upper control arms and you could actually increase caster to 3° or more.

It is only a matter of time before an equivalent prop shaft is available from a US supplier.

Sorry guys , i already have a little vibe on this shaft , i try to change the design

What was your lift height?

How is development going? Very Interested.

Looks Sven had some breakthrough,

"New specific transmission shaft Grenadier, planned for a 2.5-3 inches increase, double UJ box side and CV joint in addition 15 degrees, no harmonic vibration, mounting with specific tulip bridge side."

I have been suggesting for some time that this style of shaft would be ideal . A CV at the pinion and a double cardan at the transfer case. Glad to see that Sven finally made it happen. Others have suggested that the double cardan did not have the operating range to accommodate the angle. Sounds like this may not be correct.

Keep in mind that those are 1310 u-joints. They might not be strong enough but maybe they workout.

An abusive driver with a heavy throttle foot and running large tires could definitely have an issue with 1310 joints. But generally speaking 1310 joints are within spec for the engine output of the Grenadier if running tires up to around 35". In the Jeep world 1350 joints are typically used if running 37" and larger tires and when pushing big power often combined with Dana 60 full float axles. The upside of the 1310 joint is that it has a considerably higher operating angle. It is all about trade offs when trying to solve this particular problem on the Grenny.

1310's will be way plenty strong on the Grenadier. This is the design I was shooting for including the joint size.

I would run this shaft without concern. But I am going to wait to see if my Terra boot ever fails. If it last 20k miles I will just replace the Rzeppa when the time comes.

Are you running a lift and if so how much?

Yes, 2".
