HD UCA's

[LWM]

Thought I would give you a bump on these and see how many you have left for sale! Maybe the Arizona guys want to pick some up and do a wrenching party to install them all in one day.

Jon, thanks for the bump. At this moment three sets have been sold. Two sets in the US and one set in Australia. I expect 3 more sets in the coming two weeks. Depending on sales there will be more after that.

These UCA's are designed with the same (standard) hardware that is used for the UCA's on Tacoma's and simulair pick-up trucks used in desert racing. They are very strong and have indeed more travel than a ball joint in all directions.

I highly recommend these. They held up to some serious abuse on the trails when I trail tested the prototypes. Doc is correct...I chose the design to have a heim joint so there would end up being more travel than a ball joint and being an expert at ripping apart ball joints, I never wanted to deal with that again on a trail ride.

When you had yours did they make all kinds of squeeking noises? I heard a few members with them had that problem.

I am on the fence also,
couple of questions;
Where can you get spare helm joints?
Did you have any problems with getting an alignment?

These HD UCA's don't have heim joints. Heim Joints are spherical bearings with an integrated rod end. That's why heim joints are regularly also called "rod ends" . The bearings used are plain spherical bearings with a PTFE liner. This means that there is a teflon coated fabric in between the housing and the ball. No lubrication is required for this bearing and they are very easy to replace. These bearings are for sale all over the internet at several offroad racing stores. I have located a manufacturer and thru their distrubutor I can get the bearings and missalignments bushings. Also the poly spacers, bushings and pins can be replaced. I can get these from HM Engineering at any time. In short, all parts can be replaced and I can get those at any time.

I still have to install the UCA's on my XK but what I know from other members who has them, the alignment is not an issue. Best is to install the UCA's together with a lift so you do the alignment at one time. Since most of the members already have the lift installed you'll might have to get an extra alignment performed. This you also have to do if you install other upgrade UCA's.

Tom, did you do a new alignment on your XK once you had installed these?

So basically both units are totally rebuildable, the only difference is one uses a normal spicer ball joint and one uses a uni-ball.
