I plan to mod my SJ what does any one think of ad a leaf compared to new leafs. Also how high can you go before you need new track bars & drives shafts. I have also have a WJ anus that after a 2" lift needs an adjustable pan hard rod & new double cardan prop shaft does the SJ have such issues. What are the biggest tyres you can get on stock & with a 2" lift. I know a loft of q's but i have only had my SJ a couple of weeks, I plan to offroad it this Sunday stock & see how it copes.

Firstly take it out stock! you'll be amazed what it will do with just some decent tyres :doublethumbs:

You can go about 2-3" easily without modifications to the propshafts and steering etc but extended brakelines would be advised with a 2"+ lift (or lower the flexy mounts) above 3" and all you really need is a prop spacer and a drop pitman arm for the steering.

I would also advise the use of longer shocks with any amount of lift.

Personally I don't like add-a-leafs as they tend to be stiffer than the rest of the spring pack so the original leafs can bend around the ends of the add-a-leaf when the suspension is compressed.

Lift springs are better but 90% of the time both add-a-leafs and lift springs make the suspension stiffer and more bouncy on road.

I would recommend fitting some bedford rascal/suzuki carry rear springs on the rear and then fitting the rear springs up front by making some adapters, this also pushes the front axle forwards a bit so you have more clearance on the bulkhead for larger tyres. you should be able to fit 31x10.50s with this set up

Standard I think the biggest you can run without cutting is around 28/29". Once you get into 30"+ tyres you really need to think about lowering the gear ratios with a rocklobster transfer box etc. as well or you'll be struggling on those steep climbs and have no engine braking on steep decents.

Or if you can weld :weld: my personal favorite is a virtual lift, cutting the arches and bulkhead out and running no lift at all!

Just to point out, if you batter them enough off road, add-a-leafs and lift springs get softer in the end!
Speaking from experience ;)

But that usually takes at least a year :lol:
