Upper link bar angle

Cycled 10 inches up

You will have ~some~ pinion change because your upper and lower link arms are not the same length. If they were the same length, the pinion angle shouldn't change at all.

Just optimize the pinion angle for whatever ride height you will run the most. Other heights will be a compromise (good thing you made it adjustable *big*grin*)

I was just cycling it and I jacked he frame up 10 inches. Not planning on going that high. It's not notched so I can only cycle it one way to check for binds. I am gonna put a gusset up the upper tabs it's not ideal but should work. I don't really know what else to do there. That's where the bars fall.... I should shorten the lowers bars huh? Cuz I was told longer the better and I didn't cut any of them. I read the top bars should be 70% of the lowers

I assume you are going to go a lot further down than the 10 inches you went up. Since your upper links are tacked in you already know where your holes are. I would cut up some construction paper and play with the shape a bit until you find something you like. I think a tab that has a 90 degree angle cut into the bottom that spans the upper and side of your cross member would look good. You will need to cut them and drill them yourself. If that doesnt make sense let me know and I will use my crappy paint skills to draw something.

Longer is better to a point. The 70% thing isnt really correct and I would say that your upper bars should be AT LEAST that long. You can make them longer (or lower bars shorter).

When designing a short-long-arm "double wishbone" suspension for front suspension, a 70% upper arm is a reasonable ball park (but there is a lot more to it than that).

On a rear suspension, upper arms are only short because there is usually a back seat there.

Redid my upper bars. Found my instant center. Now my upper bars would intersect with the lowers in front of the bumper. If they kept going obviously
.. also I decided to back half it bc there was a lot of pitting on the rear rails.

[Garagely5150]

Back half removed

[Garagely5150]

Reworked upper bar tabs. Back half cut off

Bars and tabs look a lot better.
