I’m rebuilding a 4.2 XK engine from a S1 XJ6 that suffered from a very poor rebuild and only ran for a short time before failure (PO’s many, many mistakes). Because of this, most of it is in good shape including the standard size pistons that I intend to re-use.
The pistons I have are AE 21380 (low comp) short skirts. Obviously I need new rings and AE rings don’t seem to be readily available in the US.
The only ones that I’ve found that actually say in the spec sheet that they fit AE 21380 pistons are Deves 1256-B. I will probably wind up with these unless someone can suggest an alternative. The reason I’d like an alternative is because they would apparently have to be ordered and with the way things are going now who knows how long it will take.
Hastings lists Jag rings but there are 3 different part no’s and the fact that the Hastings spec sheet says the bore-diameter for some of them is 3.622 (instead of 3.625) doesn’t fill me with confidence.
So I guess I’m asking if someone can please give me the part number for a non-Deves piston ring set that they’ve successfully used with AE 21379/21380 short skirt pistons?
