Default Would like some advice

4x4parts.com has sets of hardbody ball joint spacers. One specifies for stock or after market a-arms, its .5" of lift. The other specifies for stock a-arms only and its 1" of lift. I have a rough country 2" lift on the truck. If I were to put the 1" spacers that say for stock a arms only on the rough country set up would it be a big deal??

Don't know if it's a fitment issue on why the one part says for stock arms and the other says for aftermarket, or possibly because the aftermarket arms are already angled down further to provide more lift than the stock arms.

They may have made the stock arm spacer 1" to more lift when using the stock arms I don't know.

Running the 1" spacer on the aftermarket arm may make the upper arm sit to high and effect the angle of the upper ball joint. You should contact 4x4parts and ask them, they may have a better answer.

The original Aftermarket arms were stock arms with a ball joint spacer welded in they were also boxed on the bottom. I had those on my former 87 years ago.

the driveline/cv joint angle and the brake lines are about the only three things that are affected with a big lift. as long as the lift is done correctly and those items are in spec for suspension travel, you should be fine.

Spacers do not add lift. The lift they are referring to is how much you have cranked up your torsion bars.

The spacers are intended to correct the ball joint angle when you crank up the front suspension. But here's the skinny on that: Your suspension will still travel through its full stroke at times, if you take it off road. If you add a spacer that improves the ball joint angles when the suspension is low in its stroke, it may bind when it is high in the stroke (bottomed out on a bump, for example)

Rule of thumb is to keep at least 1/2" of bump stop to prevent your suspension from drooping too far. Any more down travel than that will bind your ball joints AND your CVs.

Your aftermarket arms should be fine as they are, without spacers. If you are seeing binding, lower it a bit, and use a thicker bump stop.

I second Res. After talking with several of the experienced 4x4 guys here I decided against balljoint spacers and feel I made the right choice.

You really don't want them for the exact reason res just said, instead of the control arm bottoming out, the cv will bind, and break, and leave you stranded
