ZH1129CT-75MM these show 29 each and H1129CT-75MM show 44 each wtf? There is a thread that has the H1129CT-75MM and they wrkd on ls2 rods... are the ZH1129CT-75MM only pressed? wth does the z stand for in the part #? anyone know help me out... looking to put together an ls2 with oversized pistons on a tight budget... thanks

 

Have no Idea what the Z stands for. Did you look on there website? Email or call them and ask direct. I had to do this to get the correct part number on bearings.

 

called them and they said it was a pressed pin application so it wouldnt work then on summit it also says for vin code N which was floating pin... they dont have a clue what it fits lmao

 

So the Z designation Is for a pressed pin???

 

guess its part of summits part number

 

Since no one builds budget stuff anymore and i have limited money... For all of you that read this if your looking for a piston that works with the ls2 floating rod on a 6.0 with stock crank... part number h1129ct works standard bore, 50mm(4.020), 75mm(4.03) and 100mm(4.04) are all available through summit racing at 29 or so a pop... these are flat top sealed power Hypereutectic pistons with coated skirts...
