To be clear, a u-joint style double cardan drive shaft is what JEEP sells as an upgrade to their factory rzeppa joint shaft. See proof below:
Funny, I never knew that my u-joint style double cardan drive shaft had any problems with the angle it sits at. If anything, the factory rzeppa CV boots have a problem with them failing on lifted Jeeps due to the fact that they sit at a constant state of pinch. We have been seeing this since they first came out back in 2006. But hey, what would I know about any of this stuff.
I talked to mopar performance last month.they changed the vender making their lifts this year and no longer supply the front shaft with the kits they listed in the catalogue.it was still a good kit but i was disapointed they removed it from the set up.you have to purchase seperately now.
this is the listing
‘07-’14 WRANGLER 3" LIFT KIT WITH FOX
RACING SHOX
Utilize an exterior reservoir version of the FOX 2.0
Performance Series shock for greater heat dissipation.
The shocks, in combination with the Mopar®/TeraFlex
SpeedBump System (used on the front axle), provide
exceptional performance at speed. Additionally, this
system includes all four rear axle-to-frame link arms and
front lower link arms for ideal driveline geometry and
front end alignment (no realignment required). Includes
four tuned coil springs, brake line, track bar brackets,
Double Cardin front drive shaft (3.6L engine).
so be warned if you buy this kit it does not have the good front shaft.
altho i do believe they have updated the listing on line.
