I need to replace the ball joint boots on a Chinese MII front axle. When I jack up the front end the joints go to the end of it's travel enough to tear the boots on the upper (Chrysler) BJ's. I need stronger, longer (?) boots, any ideas where to buy them?

The Pep Boys by me has a good Energy Suspension line. I just take my broken boots and match them up. Just about every tie rod and ball joint made overseas has split on me, even before the car was running and driving.

The rubber used in parts coming out of India and China is garbage quality,there are cases of motor mounts cracking and splitting in less than a year so buyer beware. If you buy online most vendors won't know the country of origin or even post it.

Roger that quality sucks.. many hours I think my problem is the extended length of the shock is too long allowing the control arms to kick out the ball stud. Some shocks have an extension buffer from what I've read that limit travel on a properly sized shock. Found info that says jacked up with the wheel touching the ground measure the distance from the tower to the lower control arm, subtract 1/2" for the buffer and find one with that total extended length. Now I'm pouring over cataloges looking.

Many years ago, I installed a no-name set of ball joints from JC Whitney (remember them?) on a Chevy pickup. The boots cracked in less than a year, and as a bonus one of the lowers ball joints creaked!

A few years later I bought a pair of CPP upper control arms with brand new ball joints for a 55 Chevy. Both had cracked boots right out of the box. Since the boots were not replaceable, CPP sent me another pair of ball joints, and even one of those boots had a small hole in it.

If Chinese manufacturers can't use the proper boot material, I can only imagine the quality of the ball joint itself. Scary stuff!

It's been Moog for me ever since, and I've NEVER had problem with them.

Run rubber boots with leather covers. The rubber can crack and the leather will contain the grease.

Double stitch the side to make a "cone" then fold in the ends before double stitching the ends. Then simply use metal zip ties to hold the metal.

Every couple of years grab your junk shop vac and suck the old condensated grease(it happens anywhere there is air) out replacing it with new.

If the rubber boot cracks let it crack. The outer boot will keep the grease in.

Eventually you will need to replace the boots if they continue to crack due to being pulled or such because they are to short. But if you install the proper sized boots no matter the quality and then install leather covers that will greatly contain the grease within the boot area.

I will note that the homemade leather covers I talk about making above are not intended to be submerged. But for general street driving they keep your ride looking good. Being able to be made in a variety of colors (if the boots are highly visible) is also a nice perk.

Interesting factoids: https://www.suspension.com/blog/where-are-moog-parts-made/ These days you never know where things come from all we can do is hope they have decent standards regarding quality control.
