At what lift height do you need to start worrying about the angle and length of your driveshaft? Ive looked at a 6" ZONE lift and it says that it MIGHT be required and as for other 6" and 8" lifts I haven't seen it say anything reguarding this topic. I have a 07 4x4 Supercab

 

I can't say for sure but I can tell you I don't have an extension on my 6" bds with AAL. My back should come out to be taller than yours with the zone so I wouldn't see why it would be needed.

 

A spacer for the rear driveshaft will be included with the lift. For a 6" that's all you need. I guess you don't need anything more for an 8"

 

What he said^. But since every truck is just a little bit different than the other some may need it some may not. You won't really know until you have it installed.

 

I never used one for mine? Makes me wonder now.

 

If you don't have driveline vibration then you don't need it, you'd know after going a mile down the road if you needed it or not.

 

Thanks.. Nope I don't have vibration. Is the spacer something that comes with the kits or should I have bought it separate? Not that it matters now but mine didn't come with one. I used everything I got.

 

If it comes with the kit then you need to use it, if it doesn't it's either optional or not required.
