I'm looking too lift my 06 sport, I got 4 inch lift spindles for the front, and 2 inch rear shackles, is there anything else I will need too replace suspension wise or no? Also picked up some 305/40 R 22's I'll be putting underneath, lift spindles call for 16 inch wheels or bigger 4 1/2 inch back spacing or less, but the ones I have are 22 inch with 5 1/2 inch backspacing, not sure if I will run into a issue with that aswell.

I think that backspacing will be a problem. The wheel and tire are going to hit stuff in the wheel wells. But wait until someone chimes in that has more experience with that vehicle.

I just had a thought, If I put on 1 inch wheel spacers, they should then fit no? That takes them a inch further away from the truck.

So yes, a 1” or bigger wheel spacer should resolve the backspace difference and bring it in spec with the spindle…

Some wheel spacers are better than others, so don’t buy cheap. Also, when you use wheel spacers it can put more leverage on the wheel bearings, ball joints, and tie rod ends, so you will have to keep a closer watch on those things.

Also, what is your current gear ratio? You’re going to need at least 4.10 gears for those and you may want 4.56/4.88/5.13 gears.

Since you have an 09, you will also need to get into the computer and adjust the tire size. This is an absolute must with the automatic transmission. I would also highly recommend a bigger transmission cooler and a shift kit to help keep the transmission happy.
 
Also, is this truck 4x4 or 2wd?

It's 2x4 it's a sport, also it's a 06 not 09, and these came factory with 4.10 gearing, I'm more less just concerned if there is anything else suspension wise I need too change while doing the lift spindles and rear shackles, I've already had the 22s on the truck stock height and not much difference between the factory 15's slightly less torque and had too cut some of the inner edges out for fitment.
 
Torque doesn't directly care what diameter wheels you have. The combined weight comes into play, but mostly it matters what diameter tires you have on them. 305/40R22 is 31-32".

Did you check for rub at steering lock, or only going mostly straight?

Sorry, I’ll call that a typo on the 09/06, I hadn’t yet poured some coffee in my eyes when I posted that, lol.

A 2x4 is a board, you have a 4x2.

Not all Ranger Sports had 4.10 gears. I’d verify your gearing, but either way, you’re going to probably want deeper gears. But 4.10 is workable.

You are going to want longer rear shocks. Front shouldn’t matter since it’s a spindle.

You may need more than a 2” shackle in the rear. That can be achieved by adding a heavier spring pack, extra leaf or two, or a lift block if you don’t have one. I prefer no lift block.

Changing the tire size in the computer is absolutely needed with an automatic, it adjusts the computer controlled shift points among other things. You either need an advanced scan tool, access to someone with one, or a laptop with Forscan and a cable.

I've been running them all summer, they will not rub anywhere even at full lock, there 11 wides. This isn't what I'm looking for help with, I'm asking if there is any other suspension components that need too be changed out after installing the lift spindles and shackles. Thanks in advance.

Just crawled underneath, it's stamped as a 4.10 ratio, which is good in my case I guess, I will look into getting the shift points changed in the computer aswell, thankyou kindly!
 
So at this point I’m going to go ahead and move this over to the proper suspension forum, you may get a little more input there…
