i was thinking about putting a rancho sport 4in kit. my question is do i need to change drive shafts with this kit. i know alot of people say when you go over 3in you need to but i was thinking maybe it was different with this kit because of drop brackets. thanks

 

Run the stockers till they go bad.

 

those brackets just drop the arms down instead of using extended arms. it is the axle being lower than the transfer case by an amount outside of the driveshafts ability that causes the failures. I think those brackets are a smart idea. Keeps the kit cheap and ez... plus I bet keeping the arms more parallel to the ground really gives a nice ride. I would much rather have those drop brackets than a kit with fixed arms or no arms.

Like Joe said... run them till they crap out. I lost my front boot real fast on the trail. If you have an auto you will lose yours the first time on the trail too with 3+" lift.

 

I bought this kit and have been very happy with it. Keeps a lot of factory geometry so ride is good. and seems to be well built Upgrade to the 9000 XL shocks though, pretty nice to be able to dial in the ride you like.

 

Did you change your drive shaft, if not have you had any problems.
How do you know when drive shaft is going bad?

 

We do not require to replace the driveshaft. The angles at full droop and compression are well within the working angles of CV driveshafts. Don't get me wrong, the OE driveshaft is not the strongest but if you have a failure with our kit on, it would've most likely failed with stock suspension.

 

this kit is what I have, I'm very happy with it, at first i thought I was going to upgrade to a long arm eventually, but I don't see the need to do that at all, I've had it for 10,000 miles with often wheeling, my driveshafts are fine so far. those brackets for the arms are great, they give you a lot of flex

 

here's a picture of mine

 

At full droop the front driveshaft boot does not hit the skid plate on the auto? What limits it from hitting the skid plate?

 

Hm.. Curious. Do you drop the transfer case somehow to correct the angles?
