I made mine cause I went with a 9" and 63" Chevy springs so it was just easier that way for me but with 40s you might have wrap issues running blocks

 

also does any one know if the dana 60 will bolt up to the jeeps u joints on the drive shaft with a adaptor u joint from the auto parts store?

 

That I'm not sure of I know there are 1310/1330s but not sure those are 50s right?

 

idk about all this numbers but if i block the hell out of it I'm gone make a custom set of ladder bars and also the front is all set up with hiem joints already with long arms that i made about a week ago and i was thinking about making bigger spring perches for the front also and then it would b the perfect height

 

I'm sure with ladder bars it will be better I'm just not a fan of blocks lol so don't let me talk you out of it also what will help with lift and wrap is an overload leaf from a pick up

 

ya what u put on ur jeep in that pic? itt looked like it was cut shorter

 

You'll need a bastard joint, most likely 1310/1350 and you'll also need to have your drive shaft shortened. I had a bit over 2" cut out of mine and I have a almost a 3" stretch.

 

ok so 1310/1350 the part I'm gone need to fit it?

 

Bout a 90% chance. Some used a 1330 but those are rare compaired to the 1350 size.

 

I'll go on and say it: Blocks on a XJ are a bad idea! I have seen two XJ's flip on the road due to lift blocks.

As you apply the brakes hard the axle will roll rearward and will pull the drive shaft off of the output shaft then the drive shaft digs into the pavement and over you go. I witnessed this first hand on one of those occasions and it happened in front of me. A group of XJ's were convoying home from a trail ride when it happened.

It sucked to have to pull three young men out of a rolled XJ and start administering first aid after just having good fun on the trails. A deer ran out in front of the XJ, he braked hard and I watched the rear lift then roll over to the pass side then the Jeep went into a barrel roll.

I highly recommend a traction bar and a SYE with a long slip drive shaft if you do go with blocks over an inch tall.

Just trying to save you the trauma of an event like that, not preaching.

 

Ya deff gona have trac bars becuase of that reson and it is way stronger with them keeping the rear axles steady under power

 

I would hope with the lift needed for 40" tires a SYE would be installed and the drive shaft popping out wouldn't be an issue. If not carry lots of spare u-joints.

 

X2^^^^^

 

Im starting to lean towards 38s because there gona be easyier to find on cr so should be alittle easayier on the drivetrain

 

I would def make sure you have a sye still cause even 38s are hard on it
