Notes:
Non-Knurled ball joints recommended for replacing non-knurled ball joints
Due to these ball joints being tight tolerance, metal on metal ball joints, proper fitment is critical. Using the wrong style of ball joints can cause significant steering issues. We always recommend installing non-knurled ball joints until non-knurled ball joints are no longer a press fit into the axle end forging bores. If your axle end forging bores have been enlarged to the point that non-knurled ball joints are no longer a press fit, knurled ball joints are required.
Use of the improper ball joint style for the axle housing voids our lifetime warranty. It is up to the installer to verify the proper ball joint style is being used.
Compatible with RCV axle shafts

Limited Lifetime Warranty:
For the original purchaser, this warranty covers defects in materials or workmanship of the ball joint for the lifetime of the joint. Ball Joints are wear items and normal wear of the ball joint is not subject to this Limited Lifetime Warranty. The wear items of the ball joint will periodically need to be replaced once the adjustment in the joint is used up and are available separately as a ball joint rebuild kit. Length of time between rebuilds is subject to the use and build of the vehicle.

2003-2013.5 Dodge Ram 3500 4WD

Durable but to hard to chew to make squeak.
Size: 2.5" (Small Dog), Color: Pink+Red+Yellow
Nice and squeaky but a little too hard for my 25# Cockers to chew on...may be the spikes.

Used for tense muscles
Size: 3.5" (Medium/Large Dog), Color: Set of 6
I don’t use these as dog toys. I use them as therapy balls. You place it on an area of tension and lean on it. Works like a charm to take pain away!

An absolute must have in our house
Size: 2.5" (Small Dog), Color: Blue+Orange+Green
We have a couple of miniature Aussies. One is more of a snuggler, but the other is addicted to playing fetch and these balls are her favorite! Perfect amount of bounce and squeak. Perfect size for her mouth and a great value. Very durable too.

loud but in a good way
Size: 4.5"
Love these crazy loud squeeky balls. I bought two a bit too big but the dogs still love them. Yes, they will drive you insane but the dogs love them so much it's worth it watching the pups enjoy the balls. They are strong and safe as long as they aren't too small for your dogs mouth.
