Had it out over the weekend to test the shock revalve.
I went to a 15 stack with a flutter and it doesn't bottom out any more but it rides too rough in the chop.going to drop down to a 12 stack no flutter or a 12/15 combo and see how that goes. I was able to take the woops in second flored and it handled great!

I really practiced my take offs and the car doesn't start to move till the very last bit of the pedal and it's still very touchy!

Had a great time but broke a stud off of the heim joint on passenger lower spindle. Had to use a few ratchet straps to limp back to the trailer!

could you post a pic of your spindles or just one of them?

i  ask, as i`m wondering if king sand cars continued using the same spindles as short sand cars did. the spindles king has used as long as i've seen their rails. if so, and if your going to continue running them, then there are good and bad studded heims. of course, a more widely used design with double shear ends on the spindle uprights is, imo, the better way to go. this is why i asked, if you replace those studded heims with ones that are steel on steel ( especially the low carbon steel ones) or with the ones with the white nylon liners this issue will happen again and must faster. those are weak and the white nylon lined ones will lose the liner, the stud will separate, then your spindles separates from the a arm and well you can imagine the rest! only use chromolloy with kevlar teflon lined, i speak from experience.

+1! (I use QA-1)

fabr can you post a link?

also on those studded heims, it's important to pull you limit strap, drop the arms and find the point where they bind. you want to stay atleast 1 to 2" above this point and remember ....even the best limit strap stretch's 1" per foot!

http://www.qa1.net/rod-ends-and-related/rod-ends/endura-series/xm-series-chromoly-steel    The X series is what I use exclusively. Never had a failure yet but you know I don't undersize anything either.    Lots of places to buy with varying pricing but much less than FK or Aurora.   

Here's just one example.  https://www.racerpartswholesale.com/product/11560/QA1_High_Strength_Alloy_Rod_Ends

 Jegs/Summit and I think Speedway as well.
