As previously mentioned......the upper balll arm pivot is (somewhat) adjustable in increments of 1/2", by spindle or with extended upper ball joints. By doing so I can tune the angle of the UCA. The angle of the LCA is set....based on ride height. What good is changing the tie rod angle if you cannot adjust the LCA angle?. If the K builder does not have the FIXED LCA pivot point in the right place.....you can chase your tail all day raising and lowering the tie rod end attempting to adjust it, but it will do no good.
Any suspension with upper and lower arms at unequal lengths will have some bump steer at the ends up the travel, geometry makes those rules.....the goal is to get it a a minimum .....all while still using the factory UCA pivot points and frame rail location.
As I have mentioned in previous threads....the biggest disadvantage I found in utilizing a heim joint is limited travel.....especially at the narrow track width exclusive to the HDK.
BTW....ride height change of more than 1" on the HDK is done primarily by changing shocks (longer /shorter). ....by excessively cranking up the preload, you effectively stiffen up the ride
I have read where others claim their aftermarket front has longer travel......my thought is...at what track width?
I can move the HDK out 2" and get increased travel, but the price is the wheels no longer tuck in nicely.
In my experience, I could never get much travel out of a heim end, not to mention the difficulty to easily keep them clean and lubed.
