Ball Joint talk

What I wanted to discuss is regarding the screw in MOPAR style ball joint that is very popular with the tubular control arms for the venerable Mustang II suspension.

These two ball joints are very different in how they are supposed to be used

The ball joint pictured at the right is the commonly used K772 MOPAR screw in ball joint used on tubular control arms throughout the industry. If you look up that number you will see it is meant for MOPAR Upper Mid-Sized cars. It is not intended for use as a lower ball joint where it will see tension loads.

The ball joint on the Left is a K719. It has the same threaded body of the K772 but if you notice one very different difference in that body, it encloses much more of the ball stud. This is a true lower ball joint meant for the Mid-Size and larger passenger cars. While it will directly replace your K772 ball joint in the control arm, the stem is larger. This larger stem requires you to machine your spindle to accept it.

While many thousands of cars and trucks are on the road using the K772 as a lower ball joint without failure, we have seen a few. Granted, this is a very robust ball joint, and if you are using a quality joint like the MOOG Problem Solver line, you may never experience a failure. We have, on the other-hand, solved some driveability issues associated with the Mustang II suspension, mainly the nervousness out on the highway but replacing the ball joints with a true lower ball joint. Now don’t take this as the end all-cure all solution to your Mustang II suspension, it’s just something we have experienced. Because the K772 is not meant to be loaded in tension, it can be “sticky” and not let your steering wheel return to center properly.

All of our Mustang II based control arms feature the K719 on the lower, and we machine the spindles to fit. If this seems like an upgrade you would like to make, give us a call and we can take care of you.

Quick hits from around the shop

New product in the store!

As promised earlier, we have the 57-60 F100 and 55-59 GM truck Dakota IFS kits available in the store. These are for the stock arm Dakota suspension systems. If you want air bag systems, any of the kits that would fit any of the Dakota two wheel drive systems should work in our kit. However, we are getting hit pretty hard to do a dedicated IFS kit with tubular control arms and air bags. So we are going to do our best to get them drawn up and in production before Christmas!

Also in the works are engine mounts for the Dakota IFS kits. I think we have the Chevy engine mount systems ready to go and will be in the store in a few weeks. The Ford Windsor style mounts are still in need of some work to make them what we want. And if we can, the LIMA series (429-460) engine mounts also. These of course are going to require a rear sump oil pan to clear the rack and pinion like any other IFS kit on the market.

2015-11-13 13.38.32Keep an eye peeled for our new line of rear suspension kits too! There will be three kits ranging from near stock to work with your nearly stock Dakota IFS and a lowered kit as well as a hammered kit with a 5 plus inch C-notch built into the boxing system. These kits will be an un-parallel and unequal length four bar with a panhard rod. A moderately low roll center that works with pickups and all come with 100% anti-squat at ride height and minimal changes in pinion angle to curb any driveline vibration. Heavy duty construction with greasable polyurethane bushings and RideTECH shocks.

We are also working on the ’32 Ford chassis components, The front and rear bolt in crossmembers should be in production by mid-January. We are also considering a full bolt in X-member similar to our ’32 system for the 33-34 Ford frames. Let us know in the comment section what you think and what you would like to see in that kit.

New information regarding springs and brakes

I do my best to keep up with information on all of our products. I was recently informed that the earlier 1973-1982 Dodge D series rotors for the 3000 pound front axle take a different bearing and are not compatible with the Dakota spindles. I made a quick note on the D-series caliper bracket selection about this change and will soon update all of the information to reflect the correct interchanges.

This morning however, was a question about springs for the Dakota IFS kits with 302 Fords. This is a work in progress and as I gather more information about the spring selections I will add it to the list to help you guys get the most out of your front end. This new information about the spring selection is in the Dakota Tech section.
