Last weekend I installed a SPOA from LowRange including 1" drive shaft spacers, brakelines, and an Add-a-leaf. I got more lift than expected. My Samurai is now about 8" taller. I am definitely going to have to add a "Z-link".

My question is about my driveshaft. It feels and sounds like it is in a bind.

1.) Does 8" require changing the angle of the axles?

2.) If so, how tall can you go w/o a problem?

I think I'd rather drop down a few inches than get into all of that. Thank you in advance for your advice.

A basic SPOA lifts the frame 4.5" above stock. If that is all you did before adding the 'add-a-leafs' then those things added 3.5" to the mix.

Anything more than 2" requires tweaking.
I am betting that the add-a-leafs just turned your suspension into a glorified paint shaker, so you may want to swap them out for a decent set of aftermarket springs. Trail Tough sells Bonz-Eye springs that are made to take the abuse of a SPOA and will give you 2" of additional lift on top of the SPOA.

You will also need something better that a bent bar (Z-link) to keep the steering right. Look into a decent high-steer solution.

As for the axle angles, after 2" the angles are already an issue. If you go to aftermarket driveshafts with high angles you can fix most of it. At 6"-8" you can consider pointing the axles at the t-case and use CV driveshafts to fix the geometry.

It all depends how much money you want to commit to a clean, safe rig.

Thanks Bill. My Samurai is not even registered to drive on the street, and really never leaves my 350 acre hunting property, so I might pull the add-a-leaf's back out, throw on a Z-link, pump the u-joints full of grease and let it ride. I never drive her too hard and only run 7.00x15 Deep Lug tires.

From the looks of your profile you have some experiece.

Thank you for the help.

The best experiance is turning your own wrenches to see what works. Driving on your own land, at your own pace, instead of out on the street, lets you really get a feel for each change without endangering others. I'm jealous.
Wrench on.
:)

p.s. Invest in a simple roll cage. Petroworks makes an easy, bolt-in solution that can be insalled in an afternoon with simple hand tools. It makes some of the 'experiances' a little safer to learn.

Just a note...if you are having issues with drive shaft angles when on concrete it will get much worse when the suspension articulates and droops way beyond 8"....could bust a u-joint. Cutting the axle housings and "turning" them to reduce the angle is the best solution...also the most expensive.

And I agree...kill the add-a-leafs and replace with a quality spring. Add-a-leafs are about the worst thing you can do for the ride and articulation of the suspension.
