Default Piston identification
Piston identification, can anyone help me identify the make of this LS2 piston please.


Can anyone identify the make of this LS2 piston please?

Only other markings on it are no1 and .50 stamped on it.

Looks like an aftermarket 0.020" piston which is 0.50mm over or close.

Pull it out of the block. That might be a UEM Silvolite.

It’s out the block and this is the only marking on it, I can’t relate it to any manufacturer

Can you post a picture of what the out side of the piston looks like. I would like to see the coating and the ring lands.

Each manufacturer does it differently and it may help Identify it.

Well it's not a Silvolite, Speed pro, or Moresa.

The Skirt looks like an EngineTech P5041

Piston broke away on side by top ring. Trying to identify it. It measures 4.011”( in the correct place with calibrated equipment) but the bore measures 4.017. Neither makes sense!

So piston is very small for the listed size and the bore has way too much clearance for a OE replacement piston. Curious what the engine combo was?
