Was not impressed. Grease fittings doesn’t fit any of my grease guns…. Maybe because we’ve all been using Chinese products so long and these say made in USA. so had to buy those to grease it. Ball joints Litterally feel like they are seized up and now after installing my steering wonders back and forth on the road.

I really Like that These ball joints are American made and that the people making them take pride in their work! I've not installed them yet, but I can tell they are very well made.I will definitely be buying more Kryptonite products!Their warranty is also awesome!

Fit great, aligned easily after installation. Fixed my memory steering issues. Before installing, I could turn the wheel on an on ramp and it would keep steering through the ramp after I took my hands off the wheel. I think the previous owner replaced the bank joints and over torqued them. I installed these and torqued them properly, bottom to 35 lbs and then torque the top to 69 lbs and then re-torque the bottom to 150 lbs. Good to go.

The upper and lower ball joints worked great. The upper does not press in far enough to install the snap ring but neither did the OEM Ford upper ball joints. Used the lower ball joint grease zerk to fill the upper ball joint and then installed the plug. Installed the zerks on the bottom ball joints. Re used the wheel bearings and inspected the u joints while they were out.The ride seems a lot smoother but it's still a 3/4 ton truck so not like a half ton. Turning is a lot easier and no wandering. Got rid of the popping and the ball joints that I removed were Moog and rusty and worn out terribly. Hoping that I don't have to use the warranty within the next 2 years!!!

Installed on my son's 1999 Ford F250 SD when rebuilding the front end of the truck. Very well made and heavy duty. Came with grease fittings as the OEMs did not have grease fittings but they did last 26 years!

These were very high quality, its similar to comparing vandium steel tools to impact rated tools. Can tell the quality over oem; worked perfect on my 2008 f250.

Bought for 2012 F250. Truck has 150k miles w/ 37/13.50/20’s. These parts are very labor intensive to change out. So far I’m satisfied with the quality and the warranty backing this product. Time will tell.
